Dr. Decker is wonderfully personable and an attentive listener. He practices evidence-based medicine. Excellent.
I have zero complaints, everyone I interacted with outside of the medical staff was respectful. The medical staff showed a clear concern for my well being, listened intently and I never felt like anybody was there to simply do a "job". I'm very happy with Dr. Decker, his staff and the service my family has gotten from this medical facility over the years.
Dr. Decker is an exceptionally kind and caring physician. Very professional with addressing health issues. Discusses pros and cons of treatment. At end of visit always asks if there are any others issues to discuss. Feel very grateful to have him as my primary.

I think Dr Decker is a great Dr!!!
Dr. Decker is absolutely the best. He is thoughtful, considerate, kind . . . He clearly reads the research, is very willing to test out theories and admit when he doesn't know something but follows up when he figures out an answer. He's proactive about addressing issues that other providers have brushed off in the past and he clearly cares about his patients. I am so glad he is my doctor.
