My mother was referred to Dr. Oppenheim by her internalist. Making an appointment for her was easy and the receptionist was pleasant over the phone. As with most doctor offices, they are closed during the lunch hour. We were running late on our first appointment by more than the standard 15 minutes. I called to give my ETA to the personnel and they were very understanding and accommodating and still agreed to see my mother even though we were majorly late(all my fault). Aside from this, Dr. Oppenheim was very gentle and has great bedside manners. My mother and I were very impressed with his professionalism and knowledge. No doubt why he is also voted amongst the Top Doctors in the Washingtonian. If you are searching for a ENT doctor, you won’t be dissapointed with Dr. O.
