“The office contacted me to change the date of the appointment as Dr Hemann was scheduled for morning rounds in the hospital that entire week so I had to choose another date and later time. Dr Hemann is very professional, knowledgeable, to the point and takes the time to listen to concerns. The wait time was reasonable.The Rockville office is austere but other than that, it was a positive experience. ”
