Dr. Dunn is very upbeat and knowledgeable doctor. Thank you for your excellent care

Dr. Dunn is an excellent provider. I value his guidance, knowledge and expertise as my doctor as well as Barb, his nurse. I hold him in the highest regard as a medical professional. He always has time for questions and makes me feel that as a patient I'm part of the team. I would be very unhappy if I had to see another doctor. however if I couldn't see him I would want his recommendation as to see. I trust and respect him as a doctor and a wonderful person.

First time visit with Dr. Dunn. I really felt comfortable with him. I'm old enough to remember the old school family doctor who had an office in the neighboring town that cared for everyone in your family. That's the feeling I had with Dr. Dunn. My problem wasn't to serious but if it was I'd want Dr. Dunn taking care of me.
