What is a Physician Assistant?

September 25, 2026/District Medical Group
  • PA-week

Each October, a week of the month is observed in healthcare as “National Physician Assistant Week.” These medical providers are recognized for their important role in the delivery of healthcare to patients in medical clinics and hospitals. District Medical Group is proud to have many experienced, compassionate physician assistants among our exceptional group of medical providers.

What is a physician assistant?

A physician assistant (PA) is a licensed healthcare professional who practices medicine in collaboration with physicians and other healthcare providers. Working in every medical specialty, they examine patients, diagnose illnesses, develop treatment plans and prescribe medications as part of a healthcare team. PAs may work in outpatient clinics or provide inpatient care at hospitals.

Established in 1967, the profession currently has more than 200,000 PA practitioners in the United States, engaging in more than 620 million patient interactions each year, according to the American Academy of Physician Assistants (AAPA).

What is the difference between a doctor and a physician assistant?

PAs practice medicine and treat patients under the collaboration or supervision of a physician, while doctors (MDs and DOs) have complete autonomy and can practice independently.

What medical training do PAs have?

After completing their undergraduate degree, individuals who want to become a physician assistant must complete a physician assistant graduate program (master’s degree). The United States has more than 315 accredited PA master’s degree programs, which take three academic years or 27 months to complete, according to the AAPA.

In addition, all physician assistants must pass a rigorous certification through the National Commission on Certification of Physician Assistants. Once they have completed their PA master’s program and certification, the person is a qualified PA-C (physician assistant-certified).

Why are PA-Cs needed?

Access to quality healthcare is critical to the health of the community. Having healthcare teams comprised of physicians, physician assistants and nurse practitioners supports improved access to care for patients. With the addition of physician assistants to care teams, the healthcare industry and patients benefit from:

  • Increased access to the care they need when they need it
  • Improved efficiency in the delivery of care
  • More available healthcare providers to address the overall shortage of physicians across the country
  • Lower costs of care

We at DMG want to say to our dedicated physician assistants, “Thank you. We appreciate your commitment to high quality, patient-centered care.”
