Express Care

We offer in clinic urgent care services for adults and children seven days a week to help you when you are sick or injured and can’t get in to see your primary care doctor. Our services are designed to close the gap between primary care and emergency care by offering prompt, walk-in treatment for non-life threatening illnesses and injuries.

No need to be a Pentucket Medical patient, as we provide care for anyone who needs it and often for only an office visit co-pay. It is important to note that we are not an emergency department and cannot provide care for life threatening illness and injury. Please see the list of conditions we treat and call 911 if you are having a medical emergency.
