Telephone Calls

Routine telephone calls should be made between 9:00 AM and 4:45 PM Monday through Friday. Emergency telephone calls after office hours should be directed to the exchange (314) 388-6578. True medical emergencies that can not wait should prompt a 911 call. Return telephone calls by physicians will be made throughout the course of the day – please tell us how long you will be at your telephone number and how urgent the problem is. We perform endoscopic procedures most mornings and return calls in between cases or at the end of the work day for elective calls.

You may also use NextMD if this is not an emergency.
