Dr Raxlen obtained a B.A. in philosophy and anthropology from Stanford University. It was there he was influenced by his Professor, Gregory Bateson, the noted anthropologist who introduced Dr. Raxlen to "general systems theory", medical ethnology and communication theory. As a result, during his medical training at the University of Toronto, Dr. Raxlen worked two full summers in Quetzaltenango, Guatemala and San Salvador, assisting medical personnel in helping native Indian people in both countries. He completed an internship at McGill Medical School Hospital Network. He then worked a full year in the emergency room of a large Toronto hospital, as well as serving as an associate "medical house call doctor". His interest in medical anthropology in underdeveloped countries took him to Belem, Brazil and the Amazon River, where he spent a year in the Xingu River Basin. He lived with an indigenous Amazonian tribe for six months. There he studied parasitology and other tropical diseases.
This resulted in a life long interest in therapeutic herbal medicine. He returned the following year to begin training at the University of Chicago Medical School. He received a two year advanced fellowship in Family and Child Psychiatry. He was appointed to the faculty as a lecturer in Family and Child Psychiatry.
His practice moved to Connecticut in 1972 where he was appointed lecturer at Fairfield University and Assistant Clinical Professor in the Department of Psychiatry at Yale University. In 1975, he was appointed Director of the Children’s Service Center of Bridgeport and founded the Graduate Center for Clinical Studies at the University of Bridgeport.
After a decade of private practice (1978-1988) pioneering nutritional and integrative psychiatry/ medicine, he became interested in tick-borne disease (Lyme Disease) because of the chronic undiagnosed symptoms of his patients. Dr. Raxlen's practice was situated in the highly Lyme endemic areas of Westchester and Fairfield counties.
Over the past 15 years, he has successfully treated over thirty-five hundred cases of Tick- Borne Disease (specializing in neuropsychiatric and neurocognitive complications). Over 90% of his practice is now devoted entirely to Chronic Lyme Disease (CLD) and co-infections.
