Dr. Kenneth Miller is great. Kind, hard-working, really cares about your health and well-being, attentive and patient (no pun intended). I feel very comfortable with him, and with this practice.

Dr. Ana Tuyama of NYGA wasted three hours of my life for NOTHING. Very unpleasant person. She made me wait for almost an hour without an apology. She refused to perform a sigmoidoscopy -- which I need. I studied my situation, and discussed this with my primary physician in detail, and KNEW what I wanted. But she declined to listen to my reasoning. She didn't even seem to follow along, even though I explained it THREE times carefully. She didn't care and wasn't listening. She even refused to recommend anybody who WOULD do a sigmoidoscopy. She's a horrific person and doctor. By not doing this necessary procedure she may have literally KILLED me.

Dr. Leong spent nearly an hour with me. Not only did I feel heard, I also felt understood. When I left, I felt like we were on the same page with a mutual interest in my health and curiosity about my liver. I look forward to future visits as we start down a new path towards some answers!
