Both Cheyenne and Dr Hagaman we're friendly, caring and listen to me and my concerns. I did not feel rushed at all during this appointment.

I am asthmatic. Since seeing Dr. Hagaman for the past two years, I have only had to use my rescue inhaler three times. He is very knowledgeable and prescribed the appropriate treatment which has helped me to keep my asthma under control.
