"The one thing I can say puts Dr. Dimond above and beyond other doctors is that he’s never rushing you during the visit. You never feel like you need to wrap it up because he’s moving onto someone else. He stays he listens and he collaborates for your health."

"Today was my first visit with Dr Diamond.
I was very impressed with his thorough review of my history, professionalism, & compassion. Being a nurse for over 40 years, I can see he is an excellent physician & extremely knowledgeable. He made me feel comfortable, was easy to talk to, and answered all my questions. I was so pleased with him that I’ve asked him to see my mother, just diagnosed with cancer, at Huntington Hospital. I know she’ll be in excellent hands!"
