About Us

We are a group of four physicians all board certified in infectious diseases. Dr. Rush, the founding member of the group, opened the practice in Northern Westchester (originally in Elmsford) in 1987 and has been in practice there since then. The office moved to Briarcliff in 1990. We have been at our current location on Woodside Avenue since 2008.

We now provide Infectious Diseases consultations at most of the hospitals in Northern Westchester and Putnam counties including Phelps Memorial Hospital, Putnam Hospital, Hudson Valley Hospital, and Mt. Vernon Hospital, and we expect to be providing this service at Westchester Medical Center and Northern Westchester Hospital in the near future.

We also provide Infectious Disease consultations in our offices in Briarcliff Manor and Carmel where we see patients with a wide range of 
infection-related disorders and symptoms.
