Meet Our
Physician Leaders
As a physician-led organization, we are able to keep our primary focus on our patients and our practices. Like our providers, our leaders have undergone rigid medical training and have real-life experience in the day-to-day life of medical practices which enables them to be strong advocates for our physicians. Most importantly, our leaders have treated many patients in their careers and are attuned to the various needs our patients have, and as well as patients’ expectations of their healthcare providers. Together, this allows Steward Medical Group to ensure the delivery of compassionate care in a setting close to where our patients live and work.
