Specializing in Chronic Fatigue Syndrome, Dysautonomia, Mast Cell Activation, Autoimmune Diseases, Chronic Infections​

Dr. Kaufman completed his medical training at New York Medical College in the U.S.A.  He began his internal medicine practice in Greenwich Village in New York City just as the HIV-AIDS epidemic exploded.

As a result, he became deeply involved in the care of HIV positive patients, and in the research aimed at discovering ways to treat both the opportunistic infections they were dying from and the virus that was causing the destruction of their immune systems.  As HIV-AIDS became a treatable chronic infection, the practice expanded to include more primary care and general internal medicine patients, and as a result, Dr. Kaufman became involved in the diagnosis and treatment of a variety of chronic and often difficult to diagnose and manage conditions such as tick-borne infections, hepatitis B and C, fibromyalgia, ME/CFS, and other complex chronic diseases.   Dr. Kaufman is a working member of the U. S. Myalgic Encephalomyelitis / Chronic Fatigue Syndrome or ME/CFS Clinical Coalition and part of the guideline committee.

He is a founder and practicing physician of the Center for Complex Diseases based in Seattle and California, U.S.A, which has a focus on patients suffering from complex chronic disease such as Mast Cell Activation Syndrome, ME/CFS and Long COVID.
