What is a Physician Assistant?

A Physician Assistant (PA) is a medical professional who works as part of a team with a doctor. A PA is a graduate of an accredited Physician Assistant educational program. They are nationally certified and state-licensed to practice medicine with the supervision and guidance of a physician> PA’s perform physical examinations, diagnose and treat illnesses, order and interpret laboratory tests, perform procedures, assist in general surgery, provide patient education and counseling, and make rounds in hospitals and nursing homes. All 50 states and the District of Columbia allow Physician Assistants to practice and prescribe medication.

The PA educational Program is modeled after the medical school curriculum. The program is a combination of both didactic and clinical training. The PA course study is rigorous and intense. The average length of a PA education is 27 months. PA education includes instruction in core sciences including anatomy, physiology, biochemistry, pharmacology, physical diagnosis, pathophysiology, microbiology, clinical laboratory science, behavioral science, and medical ethics.

Physicians entrust duties to PAs. Within those range of duties, PAs use independent-decision-making for patient care. This team model is an efficient way to provide high-quality patient care. By design, physicians and PAs work together as a team. All PAs practice medicine with physician supervision. Dr. Carranza communicates with their PAs daily. All Dermatology and Skin Cancer Consultants Physician Assistants undergo intensive training prior to seeing their own patients.
