DANIEL J. ALPERT, MD REVIEWS
Dr. Alpert has been my primary care Physician for over 15 years and continues to provide my family. I appreciate his bedside manner and thoroughness. He listens to his patients. Dr. Alpert and his team made me feel comfortable and throughly explained to me the process for my most recent procedure. Then they called me to see how I was doing afterwards.
Outstanding care. Dr. Alpert has been my primary physician for 25 years. Takes time, listens, explains options. Genuinely caring doctor. As part of Langone Hospital he also has access to a large and outstanding network of doctors and resources.
Dr. Alpert and his staff are all extremely friendly and attentive! I'm not a huge fan of going to the doctor in general but everyone here did a great job of making me feel comfortable and cared for. I'd recommend Dr. Alpert to anyone and everyone.

BLAIR S. LEWIS, MD REVIEWS
Dr. Lewis made me feel comfortable as we spoke and he explained the process and preparation. I was hesitant about doing a telemedicine visit. But I was very satisfied and comfortable.
Dr. LEWIS performed tests at Carnegie Hill endoscopy since I had a series of episodes of intestinal disruptions. His very thorough investigation showed that I did not have a serious condition. His thorough and courteous examinations showed no signs of lasting or dangerous condition. It was a great relief to hear from an excellent physician.
I've met Dr. Lewis only once--today--and in a brief video visit focused on the procedure for a capsule endoscopy. But I could tell that Dr. Lewis is eminently knowledgeable, professional, and patient-oriented. I can't say I'm looking forward to the procedure, but I'm sure I'll be in great hands.
