St. Luke's Internal Medicine Service

Upon admission to the hospital, St. Luke's Internal Medicine Hospitalist Service will work with your primary care physician to care for you. We are comprised of a group of physicians and advanced practitioners who care only for patients during their stay in the hospital. A member of our team will see you each day of your hospital stay. At the time of discharge, we provide your primary care physician with important medical information pertaining to your hospital stay.

Our office hours are Monday through Friday 7 am to 4:30 pm. A physician is on-call 24-hours-a-day, seven-days-a-week. If you need assistance when our office is closed, please ask the hospital nursing staff to contact our on-call physician.

You can reach our office at 484-526-6643.
