A resident is a physician who is receiving four years of additional training in the specialty of obstetrics & gynecology following graduation from medical school.

Given the nature of our educational program, you may see any one of the team members during the course of your care. We assign all of our patients to a primary resident. If you are unsure of who your doctor is, please ask a staff member when in the clinic.
