Dr. Hagaman was able to get a medicine approved to couple along with my normal infusion. His nurse had everything ready by the time we left the office. I have been working with doctor in home town for 6 trying to get the appropriate pre authorization for the medication. Dr. H is amazing & I am grateful he is on my health team.
