I use an integrated approach in my evaluation and treatment of individuals with a wide variety of problems. I’m also trained in family and child therapy, and see children and adolescents as well as adults.

Some Issues Addressed:

Patient Testimonials

…here is my update after taking Dr. Cass' Hemp CBD formula for my severe juniper allergy. Not sure how much you may know about the toxic wild juniper species that grows in abundance in the entire state of New Mexico.

I have made travel plans to leave every Spring and return home when the juniper season is over.
BUT this year the juniper season started extremely early, last week to be precise! We had expected for me to fly out first Saturday in March, the 7th.
My husband was ready to call 911 because I was having trouble breathing due to swelling in my throat, bronchial and upper chest. I took a full dropper under the tongue and held it 30 seconds and swallowed, within minutes, it was short of a miracle what happened next. The FIRE in my throat stopped, the muscle spasms in my throat, bronchial and upper chest stopped!! I could once again breath more freely. I waited 20 minutes and took another dropper full, the coughing and sneezing attacks stopped, the headache stopped, the body aches stopped. I slept better.
I know the literature says that Hemp CBD helps with allergies but this left us both speechless and amazed!
Thank you so much for your wonderful formula!

After recording an interview with Hannah Hepworth for her Anxiety Revolution Summit,  she tried my 500 mg hemp oil extract, and here’s what she wrote: "Your CBD/hemp oil was in the mail yesterday!  Oh the lemon flavor tastes sooooo good!  I immediately took half a dropper full and could feel the tension melt within 30 minutes.  My husband and I both took some last night and he had a headache and I haven't been sleeping well and we both slept solid until the alarm went off and he woke up without a headache.  I love it! xo Hannah"

Hannah Hepworth,

My son has been battling sometimes debilitating migraines (and the associated nausea and auras) since he was 5 years old. When they come on, sometimes the only thing that will resolve the pain for him is a long process of being in a darkened room, running a hot bath, and waiting out the hours until they pass. 10 years later, it appears we have finally found an easy, affordable, and consistent consistent remedy in Dr. Cass’ full spectrum hemp oil extract. We tried 2 droppers of the 500 mg bottle, and within 10 minutes, the migraine that had started to kick-in was completely gone. He couldn’t believe it, and neither could we. A week later another one started…same dosage, same results. Gone in 10 minutes. We joked about placebo, but then when the third migraine started and it worked again in the same amount of time, there was no question that we were seeing a cure, not a hope. This stuff works! He also said that each day he’s taken it he has woken up the following morning feeling more refreshed and not tired. That’s really something for a 15 year old kid! Great product, can’t recommend it enough. The light lemon flavor make it pleasant for him to take as well. We are amazed and can’t wait to see what other issues it might help with. Thank you for a great natural product Dr. Cass!

Shiloh Coleman,

In just 2 1/2 weeks I have seen an improvement in my parents’ cognitive abilities. Rather than cognitive decline there is improvement! At 92 and 95 I feel that is a success!

Doreen Rivera, Founder/Owner, The Bodyful Mind

I have been using Dr. Cass’ 500mg hemp oil since meeting her at a Functional Forum presentation she gave in October of 2018. I felt the benefits in the first week! I felt calmer, a soothing of frayed nerves. I have had trouble sleeping for a number of years and have been using cannabis and while I would sleep, the cannabis would dry out my mouth. I have stopped using cannabis and now I just use Dr Cass’ Hemp Oil and I have a more relaxing and restful sleep and no dry mouth! I have noted an improvement in my skin, with less inflammation and redness. On a recent visit to the dentist I needed to have two crowns and the trauma to my gums and mouth was great. When I was taking my daily doses of hemp oil I would swish the oil around my tender gums and doing this accelerated my healing! I have tried other hemp oils and find that Dr Cass’ Hemp oil is THE BEST! Made with full spectrum hemp extract, mct oil, a wonderful lemon taste, and great care, this is the ONLY Hemp oil I will use!

Susan Grace, The Bodyful Mind

Attending Dr. Hyla Cass’s presentation on the benefits of CBD was truly enlightening. I was struck by the wide-reaching benefits of CBD for so many physical and mental ailments. I immediately began using her 1500 mg Hemp Oil and have been noticing amazing and immediate results. I take 25mg in the morning and the same again at night. I feel calmer, more focused and more even-keeled throughout my day and have been sleeping deeply through the night. I have begun using the oil topically and notice skin blemishes or scratches healing even faster than usual. My father in New Hampshire heard about my results and wanted some for himself!

Darcy Halsey, The Bodyful Mind Director of Production

Dear Hyla, I have so been enjoying using your 500mg Hemp Oil. For quite a while, I’ve been struggling with anxiety and sleep. I had difficulty getting to sleep and sleeping through the night. Taking a dropper a few times a day, starting in the late afternoon, has assisted me greatly in sleeping. The oil helps to calm the “racing” feeling in my body, alleviating my feelings of anxiety. I was introduced to your Hemp Oil through your presentation at the Santa Monica Functional Practitioners’ Forum in October 2018, and since then have used it daily.

Traci Odom, Associate Producer, The Bodyful Mind

I have recently been using Dr. Cass’ Hemp oil and had an amazing experience of its effectiveness with my daughter who suffers from extreme bouts of anxiety. I had mentioned to her that after listening to a lecture from Dr. Cass, that the hemp oil might be helpful to her. Of course, she wasn’t interested. Then a few weeks later, she was in a full blown anxiety attack, canceling her birthday celebration, and asking me to send everyone away. I quickly grabbed the Hemp oil and begged her to trust me and try it, as I put it under her tongue. My daughter previously had never been able to pull herself out of an attack like this one. Not only did we create a different birthday celebration, but she was fully present and enjoyed that day. I saw with my own eyes a complete transformation with the use of only one dosage!! She now has her own reserve of Dr Cass’ Hemp oil and can use it whenever she needs it! Thank you so much!!!


My mother and father, 91 and 94 respectively, have been on their fair share of pharmaceuticals, none of which led to any healthful benefits. During a health scare, which involved my mother, my father abruptly stopped taking his high blood pressure medication, heart medication, his cholesterol medication and his pain medication for a condition called trigeminal neuralgia (chronic facial pain). During my mother’s hospital stay, my father began showing signs of distress so I began giving him Dr. Cass’ CBD, which helped tremendously in the process of his body eliminating all the drugs he had been taking for so long. My mother has dementia and my father has a pacemaker and had quintuple bypass surgery. Both of my parents had already been using CBD when I encountered Dr. Cass' CBD formula. I could see the marked difference in my parents responsiveness to Dr. Cass’ formula. There is such a difference in the morning prior to taking their first dose, after which they become much more relaxed, focused and connected to themselves and each other and the events around them. After he quit his strong pain medication for trigeminal neuralgia for 18 years, I was worried! I administered other brands of cbd oil without much effect until discovering Dr. Cass Hemp Oil. The good news is that within 2 months of using Dr. Cass’ CBD, all the symptoms were gone. I am grateful for the quality of Dr. Cass’ CBD and entrust my parent’s well-being to Dr. Cass’ Formula.

Doreen Rivera , Founder/Owner The Bodyful Mind

I am an avid user of pure CBD oil. While the taste of some other products was unfavorable, its use was proving to be of great value. Then I attended a Functional Practitioners' Forum in Santa Monica and listened intently and happily to Dr. Cass’ presentation. Her documented results of her patients and many other studies echoed my success in using CBD for trauma, anxiety and stress. At that meeting I purchased her Hemp Oil Full-Spectrum Extract 1500 mg. Wow... what an immediate difference I experienced in the taste, potency and delivery effects of her Hemp oil. Smooth, tasty and calming! I have since introduced my mother who has moderate Dementia to her oil with the same great results! Thank you so much Dr. Cass!

Neeyah Lynn Rose Stephens, Bodyful Mind Associate Director

Hello Everyone,
I am very excited to testify how my dependency on psychiatric medicines has been eliminated! In 2014, I had been on prescription medications for bipolar disorder for 25 years:
Lithium Carbonate (900 mg),
Clonazepam (0.25 mg), and
Prolixin (2 mg) (later changed toSaphris 5 mg)
My kidney lab tests were at the upper range of the normal. One more tick and I was in the danger zone.
I contacted Dr Cass: I wanted and got the best! After a very thorough interview, she phased in natural, low dose Lithium Orotate  and reduced the prescription Lithium Carbonate (to save my kidneys) and put me on Dr Cass' AM/PM Formula, Dr Cass' Calm,Dr Cass Probiotic, Natural Calm (magnesium),Borage Oil and Tango ArithriPhase (for Joint issues).
I slowly withdrew from the prescriptionLithium Carbonate (900-600-450-300-150 mg) during which I found Dr Cass' Calm to be especially helpful, even essential. Now,  4 years later, I am living a medication-free life, continuing to take a modified program of her supplements, and feeling great.

I would like you to know that my 84 year old mother has improved 100%, after we introduced the new vitamins and supplements you gave her on the last visit. You are a genius. My husband told me that has been more than 10 years that he haven't seen his mother this good! Her mind is very sharp. Yesterday we took her to eat and she told me that we used to go to that restaurant once a week.She reminded it. Before when she was under Rexulti, Lamotragine and Bupropion, she was so sedated that she wouldn't remember that we went to that restaurant the day before. She would need to ask us constantly what day it was, and she would lay in the couch sedated the whole day. After only two months with you, she recovered her short and long memory. Recovered her balance and stopped falling. Recovered her coordination. And haven't been depressed. All she had was to adjust from the old nasty medication to yours amazing holistic formulas. She is more alive, more motivated and back to normal. We would like to thank you immensely for what you have done!


I've been purchasing "Focus" capsules from Tango for years. In addition to the product being effective, I especially like buying it from a comparatively small and independently-owned company. It is nice to be able to call and speak directly to a patient, helpful person such as John recently. My son recommended the product and the seller many years ago and I'm very glad he did!

Dr Cass’s AM & PM Brain Recovery and Brain Cell Support gave me my brain back! We first heard about neuronutrition from our friend who had a very successful rehab and recovery center, and used it to treat drug withdrawal.  I purchased Dr. Cass’ Brain Recovery AM&PM and Brain Cell Support to help my  husband’s PTSD, which has similar symptoms to addiction withdrawal. Then I decided to see if these supplements  would help me with my own brain fog, memory slowness, and poor sleep: I had gone through a number of very stressful years:  caring for my mother during her last year, having stressful work challenges, while my husband’s health was down-sliding. I reasoned that my brain had perhaps suffered similar abuse to addicts, and it could use some help with the fog and memory loss I was experiencing. It worked! My sleep is much better and the fog and memory vastly improved. Once, when I had not reordered in time and had gone for a week without my supplements, I found I was back in the fog again. My chosen life continues to stress and stretch me as I’m now on the front battle lines of environmental work to protect our immediate locale and the planet. I look forward to less stress someday, but until then, have chosen to support my very necessary brain with these supplements. I am so greatful to have found this help! Thank you to Dr Cass for thinking outside the medical model box and creating these supportive, effective supplements. Getting my brain, my life back is priceless!

Heidi Dhivya Berthoud, LMT, CYT, RDH,

Your supplements help a LOT!!! You really changed my life!!! I can see how life can be like in a whole different way. I’m excited!For example, someone did something something negative to me the other day and instead of getting angry, I could just let it go. I never could do that before. I’m a better person, too. I can help my friends, and I see that I have good heart. You’ve been an angel in my life! You saved my mom too— she is also much improved on your supplements.

Jesse, age 27,

Hi Hyla, Your FOCUS formula continues to diminish my procrastination and helps me get more done. After taking it for less than two weeks, today I discovered the great effects of your Energy formula! I’ve been in heavy duty manual labor around the house and I would have pooped out long ago before I started taking this supplement, but I’m still going strong! So…just more feedback that your stuff works! Thank you so much!


I met you at the Cavallo Point Retreat with Dr. Brad Jacobs and I bought the FOCUS supplement for what I called Adult ADHD and it is working. I feel I have better attention and focus and not all scatter brained! Thank you — it was a pleasure meeting you.

V.R., Female, Age 52,

I am writing you to thank you for creating such a wonderful product — FOCUS. I wouldn’t have been able to get through planning a conference, presenting, running back and forth three months prior to the conference to feed my sick mother every day, without it. I began taking FOCUS along with my daily vitamins. I was excited to notice a change in a couple of days: my mental clarity and energy returned! Within a couple of weeks I began feeling like myself again: I was thinking clearly, and my concentration and energy levels kept increasing. Today I am still taking FOCUS and won’t be without it.”

Theresa, Clinical consultant to a supplement company

I just wanted to thank you for the FOCUS Formula. I think is the finest supplement I’ve ever encountered. I just deeply appreciate the thought, brilliance and training that went into creating it. I also want you to know that this is first time in my life that I’ve ever taken a supplement and felt a difference! I’ve been taking it for 3 days, one in the morning and one in the early afternoon.” “I can feel a palpable difference in my clarity and in my mood swings. I’m also sleeping much better and waking up feeling great! So I just want to thank you — and order more of it. It’s fortuitous and miraculous that I ran into you, literally, the night before I was going to start taking Ritalin! Thanks again!”

Daniel, 55,

ENERGY Boost Formula “helps me during those draggy times of the day. One or two capsules and I am wide awake, alert, and ready to work at my best!”

DS Oakland, CA,

I feel like I am undergoing some sort of metamorphosis! The CALM has calmed me enough to make me realize this epiphany even greater. I would very much like to continue with it. Thank you for everything.

A colleague’s psychotherapy client; as an adjunct to psychotherapy,

Dearest Dr. Cass, I would be dead if it were not for your Nightly CALM formula. Thank you ever so much for your research. My father was a scientist and he died for what he knew. Please make sure this does not happen with your field of knowledge I could not do this psychiatric orthomolecular type without you and your team at Tango nutrition -please give a shout out to Giovanni.

Esther H.,

Taking a CALM after work is like taking a drink only better! I feel relaxed, and the day’s worries seem to disappear. No hangover either!”

RW, Baltimore, MD,

Love it. Best I have experienced ever. Noticed cognition improvement in two days. In three weeks noticed increased sex drive. At age 72 both are huge to me.

Michael Grant White, Optimal Breathing Association

After months of sobriety from various stimulants, I was still sleeping poorly and felt exhausted. However, within a week of taking Dr. Cass’ Brain Recovery AM&PM formula, I was amazed to find that I was able to fall asleep easily and deeply. I woke up rested, and my energy and focus lasted all day. I noticed that I was dreaming, too, which I hadn’t for a long time. I felt as if my brain was restoring itself!”  

Charles R., age 45,

My doctor wanted to prescribe antidepressants but I was afraid of the side effects, and of being dependent on medication, so I tried Dr. Cass’ Brain Recovery Nutritional Program and in a month, I was back to the old me, and haven’t looked back since.”

Maria, age 33,

Your “magic medicine” Brain Recovery AM/PM Formula helped me through a wild summer last year! It was all related to my addiction to prescribed pain medication, oxycontin, for chronic arm pain. To make matters worse, as a side effect of the drug, I had horrendous sleep apnea (I stopped breathing 60 times every hour at night), to the point where I was falling asleep mid-conversation, or behind the wheel at a red light. I couldn’t watch a movie or a play without falling asleep, and my marriage was in serious jeopardy because half the time, my wife was chatting with a zombie. Then I stopped the oxycontin. Almost overnight I found I could stay awake all day no problem, and I’d sleep through the night wonderfully. It was like being reborn. And I haven’t had a problem since! 
 Also, for whatever reason, I used to get the hiccups three or four times per day. I haven’t had them since July of last year. So how did I get off the oxycontin? I went into forced codeine (oxycontin) withdrawal when I left my pain medication at home when I went out of town. After five days in New York with no sleep, wild sweats and horrors too brutal to even tell, it took a while to get my system working, even once I got home. Then I called you [a friend of the family], and you recommended Brain Recovery AM/PM Formula daily, along with CALM Natural Mind pills as needed. From the start, when I took the Brain Recovery packetsalong with the CALM pills, my head got clearer, my appetite normal, and I’d just feel human again. Eventually, by the time I started my new job in late August, I think I was about 90% recovered. I’d had no idea that the pills my doctor kept prescribing me were wreaking such havoc on my body. At home we called around and I was told I should get on methadone to help with withdrawal symptoms. Happily, I listened to you instead and was able to get through that difficult time without developing a new addiction or further damaging my insides.
 I hate to think of where I’d be now if not for you and your amazing supplements! I’m happy to say that I haven’t taken anything stronger than an Advil for pain since then.
 When my arms hurt, I’ve found other ways to deal with the pain. You’ve been a huge help with this, and I can’t thank you enough. I’ll forever be in your debt for helping to make last summer more manageable with the Brain Recovery and CALM! Thanks again.

Marty Schwartz,

I have come to depend on this excellent formula for my mental health. Before taking this multi I got off antipsychotic medications but did not have this formula to take and eventually my health deteriorated. Now I have it and I got the last bottle before you were out of stock and I trust it because it is working so well for me. I will probably buy two at a time now. Please please get back to me soon. Thank you,

Esther Hohenberger,

Since I was a teenager, I’ve had serious problems with anxiety and depression. For many years, I was maintained on drugs whose side effects were nearly as bad as the problems they addressed. Among other things, I had to give up a full scholarship and drop out of college because of my problems. When SSRIs became available, my life changed profoundly for the better. For one thing, I was eventually able to return to school and earn a doctorate in clinical psychology. I’ve been taking one or another antidepressant for many years, despite the expense and side effects, because I thought I had no choice if I wanted to maintain a reasonable quality of life. The lowered libido has been especially distressing, which is why I had discontinued the medication every couple of years to make sure I really still needed it. For some years now, the one I’ve liked best is Lexapro. Because it was not on my insurance formulary, I’ve had to go out of pocket. Each time I weaned myself off the drugs, I inevitably experienced return of my depression and anxiety within weeks. Several months ago, I decided to give 5-HTP a try, even though I was a little worried about how it might turn out if it didn’t work. I had heard Dr. Cass speak a few times and bought a couple of her books. Then I checked out her website and decided I trusted her. For one thing, she’s an actual psychiatrist…that means a lot to me because there are legions of unlicensed people out there who make expansive claims about alternative treatments. I would never have believed it! Six months in, no symptoms and absolutely NO side effects – libido or otherwise. And the same efficacy as I’ve had from the prescription drugs. 5-HTP has virtually changed my life. I give it my wholehearted recommendation.

P.O., Ph,D. Los Angeles, California,

As a speaker and writer, I have to keep my brain sharp. For the past year or so (I’m 60) and I noticed I was forgetting words, names, phone numbers, etc so I ordered your Brain Cell Support Plus formula. After a couple of weeks on it, 2 capsules twice a day, I found that I was remembering things far more easily, and my writing and speaking flowed more easily. I wasn’t forgetting words or names, either. I plan on continuing to take it, and I thank you so much for making it available.
Dennis, Age 60,

Good Morning Dr. Cass! I wanted to send you a quick note to say “thank you” for what you do and Brain Cell Support! Approx four months ago, my mother was an “over prescribed” dementia patient living w/ elder abuse in Palm Desert. We brought her home, detoxed her and met with Dr. Karen Josephson, MD who introduced us to you and your products. The best day! Today, my Mom’s appearance, behavior, and mental ability have utterly changed and she continues to improve. Now, her Namenda and blood pressure pills are supplements to your products! We are strong believers and want to thank you for leading the way!

Susan Burns, and my Mom, Norma Bonner,

My father has suffered from Alzheimer’s since 2008.  His doctor recently put him on Brain Cell Support Plus, and it has really made a positive difference in his cognition and awareness.  We are very happy with this product and would recommend it!

Rebecca Noblin,

I only really appreciated the efficacy of the Brain Support Plus formula after my patients were without it for a month. The families called me desperately wanting it and noticed the decline in their loved ones. No other supplements seemed to have the benefit of this formula. I unequivocally see the improvement in my patients and recommend it to all my patients with cognitive impairment.

Karen Josephson, MD, Internist and Geriatrician

I have found the ingredients in Brain Cell Support Plus to help tremendously after sustaining a concussion a year ago. I noticed a difference within the first week with increased concentration and memory capability and stopped it when my first year of grad school ended only to have the symptoms return when the next semester began. I re-started and the symptoms are much more manageable. Thank you!

I purchased Focus and Energy Boost for my son who is transitioning off of his ADD medication. He is not experiencing withdrawals since he started taking Focus and Energy Boost. Thank you Dr. Cass
