Dr. Klapowitz is a class act. I have seen him regularly for many years. I lead missions to Africa and he has been fantastic advising me on travel medicine issues. He is incredibly knowledgeable and very reachable. I could not recommend him more highly.

Dr. Klapowitz is friendly, always pleasant, and always focused on my health and whatever my concerns are, and he listens to what I'm saying and always takes me seriously. He keeps great records that are always at his fingertips, so there's never a question about whether has has the correct and current information on my tests, bloodwork, etc. His staff is courteous and professional, and there's never a wait for my appointments.

Dr. Klapowitz has been my personal physician for many years and I feel very fortunate to have had such excellent care. He is very dedicated to his patients, exceptionally knowledgeable, compassionate, responsive, and breaks everything down so that it is easy to understand. His referrals have been useful. His staff is organized, caring and very pleasant. Highly recommended.

Dr. Klapowitz is an extremely knowledgeable and experienced physician with an amiable, relaxed and reassuring demeanor. He takes the time to hear, understand and address all patient concerns in a thorough and engaged manner, which ensures that the patient comprehends his diagnoses, recommendations and rationale, and minimizes stress. His personal interactions and office policies reflect empathy and fairness. His staff is likewise professional and considerate. Both my wife and I have visited with Dr. Klapowitz and are extremely satisfied.

Dr. Klapowitz provides great attention to my questions and concerns and is always discussing my best interests. He provides great care and makes coming to the office enjoyable. It is a great practice that I would recommend to others looking for a general/internal medicine doctor.

This was my first visit with Dr. Klapowitz and his wonderful staff, all so very personable, thorough and efficient. I had gone to Avenue Medical Associates quite some time ago when I had been working in NYC, but opted to have my internist closer to home here in Huntington L.I. when I left my job in NYC. But the switch back to his office and staff, I feel, has been a very positive move. He was very thorough, listened to all of my concerns and provided for a regimen to address and alleviate any and all concerns and medical issues. I could not have had a more rewarding introduction to him and his very supportive staff. Thank you all and in particular to his very special office manager Lori.

With much sincerity,
