Dr. Joseph Cohen Cannabinoid Medicine

Dr. Joseph Cohen,
Physician and Medical Director of Holos Health

After completing his residency training in conjunction with the Yale University School of Medicine, Dr. Cohen spent 30 years working with patients in obstetrics and gynecology. He was in his early 60s when he needed a change of pace. After all, he’d assisted nearly 10,000 women and families through the birthing process. Not easy.

However, Cohen never imagined his next career would be in cannabinoid medicine where he’d go on to impact approximately 25,000 patients at the clinical level.

That pivotal moment, his segue into cannabis, came in 2009. Dr. Cohen had just returned to the U.S. after a few years of working with indigenous tribes in New Zealand. 

When he took a job counseling medical cannabis patients at the back of a dispensary, it changed his life forever. 

“I had no idea I’d be doing cannabis medicine. Never had any thoughts about it. However, once I started working with it, I began to realize there may be something to this medicine.” 

“I realized I could actually combine cannabinoid  medicine with functional medicine in a medical practice and really help people,” Cohen says.

This is exactly what Cohen has been doing for the past eleven years with his practice Holos Health, combining cannabis and functional medicine.
