Our Physician Extenders

Dedicated to health, wellness and education

Physician Extenders play a critical role to help assure that patients are provided with the highest quality of care. Your Endocrinologist may work with a Physician Assistant (PA), Nurse Practitioner (NP) or Clinical Nurse Specialist (CNS). All three disciplines have completed bachelor’s degrees and most have a master’s degree.

The Physician Extenders at TD&E are licensed by the State of ** and can prescribe medication. All have had rigorous clinical training and have taken national board exams to certify them in their areas of expertise. They must complete a set curriculum of continuing education each year, just as your physician is required to do to maintain their license. In addition, all of our physician extenders are required to become Certified Diabetes Educators (CDE). This is done after they have acquired the required number of clinical hours to make them eligible to sit for the CDE exam.
