We are a group of four physicians all board certified in infectious diseases and one Physician's Assistant.. Dr.Thomas Rush, the founding member of the group, opened the practice in Westchester (originally in Elmsford) in 1987 and has been in practice there since then. The office moved to Briarcliff Manor, NY in 1990. We had been at an office on Woodside Avenue from November 2008 until July 2019. We are now currently located at 302 Chappaqua Road, Briarcliff Manor, NY 10510.

We provide Infectious Diseases consultations at most of the hospitals in  Westchester County including Phelps Memorial 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 where we see patients with a wide range of 
infection-related disorders and symptoms.
