GREAT Patient care! Awesome personality, very nice assistant.
Always friendly and helpful.
Perfection! A patient for years, great staff friendly and knowledgeable well organized office. Dr. Diehl is always thorough to make sure surgery is medically necessary. If he sees you need a different type doctor he will refer you. A lot of people fear surgeons are too eager to cut, not Dr. Diehl. He is the best! Techniques are on point. Appreciative he is the reason I am able to continue my passion skiing!

Dr. Diehl never changed with his opened conversation that made me and wife asked question regarding my health issue. He always approached his patient with smile, showed concern and being supportive.
