Certified Nurse Midwives

For 34 years, Signature OB/GYN (formerly known as Esposito, Mayer, Hogan) has offered a team of Certified Nurse Midwives to help care for our patients. They have been an integral part of our care team, helping to provide well women visits and participating in care during deliveries at the hospital.
To maximize the benefits of midwifery care for certain low-risk patients, we have changed our focus to office-based midwifery care. This allows us to share midwifery care amongst more of our obstetrical patients and focus on education to contribute to the best birth outcomes. Our physicians will carry that through and support you with your hospital care and delivery.

As of the beginning of September 2020, our midwives will still provide antepartum and gynecological care in both our Columbia and Eldersburg offices, but will no longer be practicing at the hospital to care for you while in labor. Due to staffing changes, the midwives will not be able to cover labor and delivery call on the weekends starting July 1, 2020. One of our physicians will help you welcome your new baby.
