A Team Approach to Prenatal Care

In order to provide you with quality care, we endorse a team approach to your prenatal care. At the initial visit, we will obtain health information regarding you and your family.  Your primary physician will perform a physical exam at the next visit.  The physicians or nurse practitioner will see you on an alternating basis throughout your pregnancy. This rotation of Ob-Gyn doctors allows all of our staff to be familiar with you and to provide comprehensive prenatal care.

All six physicians provide labor and delivery care on a rotating basis. This rotation allows your care to be delivered by someone who is energetic and not burdened by excessive fatigue.  While we are occasionally able to honor special requests for your delivering physician, we cannot guarantee this due to the unpredictable nature of obstetrics.
