What is the role of a Physician Assistant?

Our physician assistants assist our doctors in making the most of your office visit. You may be scheduled to see a PA for injections or pre-operative/post-operative visits when your physician may not be available. They take time to answer questions both in the office and over the phone, including returning calls when necessary. You may also see them on rounds at the hospital.

Many of the surgical procedures we perform require the assistance of another skilled practitioner in addition to your physician. Our physician assistants work alongside each of our physicians in many of their more technically demanding procedures.
