Meet Our Staff

Aubrey Brinneman, CNM, MSN – Staff Midwife

Aubrey Brinneman has joined our practice in the fall of 2022 as our newest Certified Nurse-Midwife! Aubrey is from Fort Wayne, and recently finished her graduate degree with Texas Tech University Health Sciences Center. She has four little ones of her own, three of which were beautiful water births with Stephanie at Auburn Birthing Center, all three boys caught by their dad. Their older sister loved getting to participate and hold her mother’s hand. Aubrey feels blessed to have had many special moments with the Auburn midwives, and is honored to be a part of your healthcare team and looks forward to helping you have a positive birth experience. Her family loves to travel and explore, so they usually take a couple of big trips each year. One of their favorite places they visited was Montreal, and they hope to get to visit some new countries soon.

Stephanie M. VanderHorst, CNM, MSN – Midwifery Director

In 2003, Stephanie M. VanderHorst, CNM, MSN, became the first certified nurse-midwife credentialed at DeKalb Memorial Hospital and Auburn OB-Gyn. She welcomed her 2000th birth in the spring of 2020. This milestone, and the rapid growth of midwifery in Auburn since beginning her practice, is evidence of Stephanie’s favorable impact on women and families in the region. She is the mother of four children: Justin (Maddie), Jacob (Leah), Josiah, and Jozelynn; and she is the grandmother of three. She has been married to her husband Dean since 1992. Dean is an avid outdoorsman; a love they share as a family. The support of Stephanie’s family has enabled her to succeed in her dream career as a nurse-midwife. Since before she attended midwifery school, Stephanie has worked toward developing a freestanding birth center option for the women of our area. This option has been a missing link in birthing services that are available. She currently serves as the midwifery director of Auburn Birthing Center, LLC, DeKalb County’s first fully accredited free-standing birth center. Dedicated to the women in her care, she has tirelessly attended many all night births with her knitting in hand. Her goal is for every woman who wants a midwife, to have a midwife by her side.

Kori B. Engdahl, CNM, MSN, WHNP-BC – Staff Midwife

Kori joined Auburn OB-Gyn in the spring of 2012. She has truly enjoyed witnessing the growth of the center and the development of a broader range of options available for childbearing families. Kori respects that birth is both a transformative event and a spiritual passage for each member of a growing family, and for the family as a unit. She believes each client will travel their own path, and all clients should have access to a full range of options in order to achieve their own “best birth.” Kori seeks to empower clients to see their unique health needs as a reflection of their own potential for wellness. Kori is married to Adam Coffman, a university mathematics professor. They reside in Fort Wayne, Indiana with their children, Daphne and Jonas.
