Dr Ntim has excellent personality and memory. He excels in his position as a thyroid doctor and has a reassuring welcoming effect on his patients. I only make my folloeup appointments on a day I know he will be in the office. Thanks to my confidence in Dr Ntim I am a client of your practice.

Kathryn R. • September 06, 2025

Dr Ntim is so personable and fun. He puts you at ease right away. He is very thorough when discussing labs and makes clear, easy to understand recommendations on how to better manage my diabetes and prevent kidney damage. I wish to continue with Dr Ntim as I feel more comfortable with him and he is so knowledgeable of his specialty.

Patti S. • August 19, 2025

Dr Ntim is a fantastic Physician, however, the office staff leaves a LOT to be desired. Listening and/or listening comprehension is NOT a thing with employees who answer the phones. Apparently, compassion isn’t either…
