After Hours Care

There is always a doctor on call when the office is closed. You can reach the doctor by calling the office and following the prompt that will redirect your call to our answering service. If anything is wrong with the phone system, you can reach the answering service directly at 240-638-9743.

If your child has a life-threatening emergency, call 911 right away. Once you have contacted 911, call the answering service to let the doctor on-call know what’s happening to your child.

If your emergency is less severe, you should get in touch with the doctor on-call. If you need to speak with the doctor right away, tell the answering service it’s an emergency, and you should hear from the doctor promptly. If your child’s problem is less urgent, you should hear from the doctor within the hour. If you do not hear back within this time frame, call the service back and have the doctor paged again.

Most problems that occur at night can be managed over the phone. In some cases, your child may need to be seen at an emergency room or an after hours clinic. Unless the emergency is life threatening, we prefer to talk with you to recommend the most appropriate facility to see your child.
