Health Care Provided by Mid-Level Providers/Physician Extenders


Our Clinic(s) often offer health care by Physician Assistants and Nurse Practitioners. If at any time you wish to see a Medical Doctor, please notify the front desk and we will be happy to assist you with this request.

Mid-Level Provider/Physician Extenders

In addition to physicians, you may encounter mid-level healthcare providers during an appointment at our facility.

These mid-level healthcare providers, also known as Physician Extenders (Nurse Practitioner, Physician Assistant, or Clinical Nurse Specialist) are a part of our care team and allow us to provide better service to our patients.

You may make your follow-up appointment with one of our Physician Extenders who work with your physician to provide medical care for you.

The Physician Extenders provide diagnosis and testing, start or modify treatment, refill prescriptions, meet educational needs and perform some procedures.

You will not always see the physician during your visit with our Physician Extenders.

However, please know that you are always able to schedule an appointment with your doctor should you desire.
