Assessment and Treatment Center

The Roswell Park Assessment and Treatment Center (ATC), formerly known as the Acute Care Center, is a patient care service that supports our current patients with immediate but non-life threatening symptoms during the day and when our clinics are closed. 

Please know that this is not a walk-in clinic and does require a referral from your Roswell Park physician or the physician-on-call. If you are experiencing non-life threatening symptoms, you should call your Roswell Park clinic. If your clinic is closed, call Roswell Park at 716-845-2300.


Monday – Friday, 9 a.m. to 9 p.m. (last patient intake at 8:30 p.m.)*

Weekends, 9 a.m. to 5 p.m. (last patient intake at 4:30 p.m.)*

*Note that if you are experiencing non-life threatening symptoms after the ATC closes, you should still call us at 716-845-2300. There is always a physician on call to help you.
