One of the nation’s foremost experts, authors and speakers in the field of integrative medicine and psychiatry for over 30 year, Dr. Cass has helped countless individuals take charge of their mental and physical health. Known as “the non-drug psychiatrist,” she is recognized for helping individuals to withdraw from both psychiatric medication and substances of abuse using natural means, including hemp oil/CBD and other professional grade supplements.

Dr. Cass appears often as a guest on podcasts, summits, radio, television and in national print media. She is also the author of a number of popular books including: Natural Highs, 8 Weeks to Vibrant Health, Supplement your Prescription: What Your Doctor Doesn’t Know About Nutrition, The Addicted Brain and How to Break Free, and Your Amazing Itty Bitty Guide to Cannabis.

A native of Toronto, she graduated from the University of Toronto School of Medicine, interned at Los Angeles County-USC Medical Center, and completed a psychiatric residency at Cedars-Sinai Medical Center/UCLA School of Medicine. She is a Diplomate of the American Board of Psychiatry and Neurology (ABPN), and of the American Board of Integrative Holistic Medicine (ABIHM). Based in southern California, she has a limited virtual practice.


The concept of doctor as authority figure is rapidly being replaced with a more progressive view of doctor as health partner. Dr. Cass follows the following principles:

  • Treat the whole person – mind, body, spirit, and environment.
  • Determine the deepest root causes of symptoms, using scientific lab testing if needed.
  • Apply a continuum of treatments, always beginning with the safest and most natural possible.

In this way, we have the opportunity to help heal our health care system, our communities, our planet, and ultimately, ourselves.
