I feel so lucky to have had an appointment (for my son) with Dr. Hagaman. This was an initial appointment for my son, a young adult profoundly affected by autism. Dr. Hagaman was kind, calm, and easy to talk to. He showed interest in our helping with my son's allergy problem. Dr. Hagaman Is very knowledgeable, and is very good at answering questions. He never seemed rushed. He did a great job of explaining treatment options. He kept me involved in decisions, and his recommendations showed an understanding of factors specific to the patient (my son). Also, I appreciate that he set a follow up plan, and documented it clearly in the after visit summary.

He's incredibly attentive and I value his expertise. I have seen a major reduction in flares/symptoms under Dr. Hagaman's care. I have achieved greater life satisfaction, because the care plan he has provided me is specific to my health needs.

I was very happy with Dr. Hagaman. He was so friendly and easy to talk to. He explained everything to me in detail. It was well worth the trip we made from NE Florida. I highly recommend him to others.
