It is because of the concern and care afforded me without making me feel like I am on the assembly line that I always recommend Dr. Hagaman and staff to anyone needing this care.

Dr Hagaman was fantastic! Took his time. Listened closely to what my concerns were and gave me feedback regarding what he was thinking. Didn't draw a quick diagnosis, prescribe treatment and boot me out the door. He considered various option, gave me great advice which has helped already, and charted a course of action to address it my needs. Couldn't be happier with my treatment. Dr. H. Is an all star in my book!!
