Urgent Care: Assessment and Treatment Center

The Roswell Park Assessment and Treatment Center (ATC) is a patient care service that supports our current patients when they are sick with urgent, but non-life threatening symptoms. It is open 24 hours a day, 7 days a week, thanks to generous donations to the Roswell Park Alliance Foundation.

The ATC is not an emergency room and it does not accept walk-ins. To be seen in the ATC, you must be referred by your Roswell Park physician or the physician-on-call.

If you are experiencing non-life threatening symptoms, you should first call your Roswell Park clinic. If your clinic is closed, call Roswell Park at 716-845-2300 to be evaluated by a Triage Nurse. As always, in the case of a life-threatening emergency, you should always dial 911.
