I receive excellent care from all physicians I see at Weston. Dr Nagarajan is absolutely at the top of that group and has consistently taken personal care as demonstrated by my recent TURP surgery where Dr Nagarajan took multiple actions to ensure the risk of a carcinoid crisis occurring was minimized during the operation. In addition, he always finds time to chat on other matters as a friend, not just a doctor.

I have been a patient for 6 years, The Cleveland Clinic has become a behemoth and I have been removing myself from care there. Impossible to get appointments and doctors who dont really care. If Dr. Nagarajan was not my doctor, I would have left long ago. Dr. Nagarajan is the best doctor anywhere.
