Meet Our Providers

Physicians Urgent Care is locally owned and operated by six emergency room physicians. We employ 25 area providers to see patients in our clinics. They are comprised of Medical Doctors, Doctors of Osteopathy, Physician Assistants and Nurse Practitioners. All have multiple years of experience in urgent care clinics.

All care, medical decisions and procedures are directed by ER physicians, which means that our medical professionals have the ability to interact with the physicians all day, every day.

Our providers are the heart of our clinic. They all have very diverse backgrounds and are dedicated to providing the best care to you and your family.
