Proudly Serving More than 1,500 Arizona Physicians

Arizona State Physicians Association (ASPA) has a rich history dating back to 1986, when it was established as a traditional Independent Physician Association (IPA). Over the past three and a half decades, our organization has undergone significant growth and evolution, with our membership expanding from an initial 500 physicians to a current total of over 1,500 healthcare providers.

Today, ASPA is proud to be the largest independent physicians-owned and operated association in Arizona. Our physician network has grown to provide high-quality care to over one million beneficiaries, making us a significant player in the state’s healthcare landscape.

Throughout our history, we have remained committed to our founding principles of delivering exceptional patient care, promoting the interests of our physician members, and fostering a culture of collaboration and innovation. Our growth and success are a testament to the hard work and dedication of our physician members, as well as our ability to adapt to the ever-changing healthcare landscape.”

Our commitment to physician advocacy drives our mission and inspires us to continually work on behalf of our members and the patients they serve.
