Contact & Locations

In the event of a life-threatening medical emergency, call emergency medical services at 911 immediately. DO NOT WAIT! Inform the emergency room staff that you are a patient of Dr. Shimoura and they will contact us.

If you have an urgent medical need and need to talk to Dr. Shimoura after our regular hours, please call our office at (301) 570-1333. A doctor is on-call 24 hours a day. Your call will be returned promptly.

Dr. Steven Shimoura at Comprehensive ENT is affiliated with Montgomery General Hospital.

Prescriptions and refills for established patients of Comprehensive ENT are routinely issued during our regular office hours (see above). You can make your request by calling our offices at (301) 570-1333 in Olney, Maryland or (410) 740-0072 in Columbia. 

No refills are issued during the evenings, weekends, or holidays, as the doctor does not have access to your medical records during those times. It is helpful to anticipate your refill needs to avoid an interruption in your medication therapy.
