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,

Dr. K is fantastic. He is very thorough, he never rushes, he answers all questions and he runs on time. Dr. K is also very responsive if you call his office or email him through the portal.
