About
Dr. Jeffrey R. Kaplan grew up between Geneva, Switzerland and London, England, shaped early by a father who worked for the World Health Organization. He earned a BSc with honors in Zoology from King's College, London in 1978. He then completed his MBBS at St. Bartholomew's Hospital Medical College in 1982. After finishing medical and surgical internships in Plymouth and Hastings, England, he worked as a Resident at the American Hospital in Paris in 1983. He pursued further training in the United States, completing his Internal Medicine residency in Canton, Ohio from 1984 to 1987. The American Board of Internal Medicine has certified him since 1988.
A visit to his brother in Baltimore, now a Professor of Neurology at Johns Hopkins, drew Dr. Jeffrey R. Kaplan to Maryland. He bought his first home in Federal Hill in 1989 and still lives there today. He opened his solo Internal Medicine practice in Ellicott City in 2002. His civic engagement includes serving on the Board of MedChi, the Maryland State Medical Society, and chairing the Medical Economics Council, the International Medical Graduate Section, and the Public Health Committee. Patients describe him as no-nonsense, knowledgeable, and genuinely caring. Outside of medicine, he enjoys soccer, travel, music, and European political history.
