Patient Comments (7)
in Sayville, NY |
I went to Dr. Terrana for a second opinion, since my last Dr I was not satisfied with. I'm so happy I found Dr. Terrana, he is the most passionate, caring, understanding Dr. I have ever met. He makes you feel so comfortable and definitely takes his time explaining things to you. I wish all my Dr.'s were like him. I couldn't have asked for a better Dr. I HIGHLY RECOMMEND him, I am so upset I wasted my time with the first Dr. just because the office was close to home.

Best Endo I've ever had, A+++!
in Ronkonkoma, NY |
He is an excellent practitioner. He's kind and understanding and has helped me learn more about my illness, and ways to keep things under control. I appreciate the amount of time he takes for each visit. I don't feel rushed or my questions ignored.

Dr. Terrana is plainly stated the best doctor I've ever had. I was diagnosed as a type 1 diabetic in my thirties and he helped me through the hardest parts and praised me through the good parts. That was over ten years ago and I followed him to his new practice and I'm grateful for his patient care. He is the type of person who not only has an excellent 'bedside manner' but also is passionate about the science behind what can be a total nightmare for a diabetic. If only everyone was as good!

Very compassionate Doctor, listens to patients concerns, answers all questions, and schedules patients accordingly to time needed
in Nesconset, NY |
Dr. Terrana has been treating my diabetes for over 10 years. He is thoughtful, through and very patient oriented. I have never had a better endocrinologist. Can't say anything bad about his practice. He is the standard that all doctors should strive for.
