Training & Education

Dr. Cohan’s medical training coincided with the early years of the AIDS epidemic in the 1980’s. While most of his medical colleagues were shying away from this devastating, poorly understood and highly stigmatizing disease, Dr. Cohan received specialist training in HIV care at San Francisco General Hospital and devoted his medical efforts to combating this new plague, caring for desperately ill and often neglected patients.

After 25 years on the front lines of the HIV/AIDS epidemic, Dr. Cohan is now nationally recognized as a leader in HIV-related healthcare and research. Dr. Cohan has cared for over 2,000 patients with HIV and has been an investigator in over 50 HIV-related treatment protocols.

Dr. Cohan has written articles and lectured throughout the United States on AIDS and its treatment, the wasting syndrome, the lipodystrophy syndrome, pain management, and hormonal and exercise therapies. He is also an expert in male hormonal replacement for the treatment of age- and disease- related hypogonadism.

Fortunately, with advances in drug treatment, HIV has become more of a “chronic manageable disease,” today, losing much of the stigma that it once had throughout the nation. Dr. Cohan has therefore returned to his roots as a primary care Internal Medicine physician, serving a wide variety of adult clients at the Robertson Diagnostic Center in Beverly Hills, California.

Dr. Cohan is a devoted athlete, beginning with his 5-year rowing career for the crew teams at Amherst College and Cambridge University, where he qualified and rowed in the Henley Royal Regatta.

As a medical professional, Dr. Cohan served as the Senior Triage Physician for the Ironman World Championship Triathlon on the Big Island of Hawaii for two years. Through his medical practice, Dr. Cohan continues to dedicate himself to treating professional and amateur athletes with sports medicine-related issues.

Dr. Cohan has functioned in a professional advisory capacity for the scientific community, and has been an outspoken advocate for his patients from Los Angeles to Capitol Hill on controversial issues ranging from anabolic steroids, to medical marijuana to HIV/AIDS.

To help with public perception and accurate portrayal of medical issues in the media, Dr. Cohan has served as medical advisor on and off-camera, including:

  • Advising HBO Pictures 1993 production of “And The Band Played On,” based on Randy Shilts’s book chronicling the history of the AIDS epidemic.
  • Hosting two popular medical radio programs on Los Angeles talk radio (KABC, KFWB).
  • Serving as the featured physician on the 2010 Bravo reality television series about weight loss, “Thintervention.”
  • Authoring a widely-read medical/health blog on Facebook entitled “The Medical Soapbox.”

In addition to his private medical practice, Dr. Cohan served as the Chief Medical Officer of an international stem cell research and treatment company (TotipotentRX, LLC) and, subsequently, as Medical Director of its successor Cesca Therapeutics, Inc.—both of which were devoted to developing and deploying new regenerative medicine techniques to treat and/or cure multiple disease states.

My philosophy about ideal medical care is both simple and progressive. I believe that the best doctors are open-minded, willing to combine traditional (Western) and selected alternative (non-Western) medical therapies with excellent preventive care, and try to foster a highly collaborative relationship with their patients. My medical practice is designed to create a safe, caring, convenient and comprehensive health care environment for you.
