Dr. Dinning was very personable and friendly. He did a thorough health history. He took the time to explain the upcoming procedure in detail, along with answering all questions and concerns. We highly recommend him!!

Love Dr Dinning - was referred by a friend - to the same practice as another doctor I didn't like. But Dr Dinning has a great personality and REALLY listens and gives you reasons for what he recommends for you. He tries to keep treatment to a minimum - not overloading you with tests and procedures. Love him.

The phone system and hired help is a NIGHTNARE. To talk to a live person is impossible AND they NEVER call you back, even "in 48 hours" like they promise !!!

I can't believe the average of the ratings for this superb physician! I've had a lot of doctors since I'm disabled and 63-years-old, and he is one of the BEST 3 I've ever had. If I could, I'd rate Dr. Dinning a 10 on this scale. His knowledge of his specialty is wide and deep, and he keeps right up with current developments. His "bedside manner" is great. He has a down-to-earth personality that makes you think you're talking to an old friend. I recommend him totally.

As a Registered Nurse who has worked in the field for 30 years, I think I know a little bit about doctors, and Dr. Dinning is one of the best. Not only is he highly respected by other members of his profession, but he goes the extra mile to make sure his patients are well cared for after the fact. Surrounded by a team of caring professionls, he takes his time and follows up, and I can say without reservation that his bedside manner is a reflection of how much he truly cares for his patients. I wouldn't place the health of my wife and myself in the hands of anyone I didn't trust, and after working with hundreds of doctors over the years, I can honestly say that Dr. Dinning is one of those physicians that I consider to be a cut above the rest.

I find Dr. Dinning to be the kindest and most caring doctor I have ever had! He listens...and actually HEARS me, answers questions in easy to understand language, and makes me feel as though I am the most important patient in his practice. His easy going, relaxed manner put me at ease immediately. I feel he takes extremely good care of me with a smile!! Simply the BEST :)
