Meet the Team

Mary Ann Sorra, M.D., OB/GYN, Ascension Saint Agnes in Baltimore, Maryland.

Mary Ann Sorra, M.D., OB/GYN

Mary Ann Sorra was born and raised in Baltimore, though her family is originally from the Philippines. She earned her undergraduate and medical degrees from the University of Maryland. In 2001, she completed her residency in obstetrics and gynecology at Sinai Hospital of Baltimore. Prior to partnering with Saint Agnes to start Natural Fertility Care she was in private practice and also held a teaching position for the Ob/Gyn residents at Sinai Hospital. Dr. Sorra stopped prescribing artificial contraception and adopted the use of natural family planning in her medical practice in March 2009 (read more).

She believes she became a better doctor after making that transition – better able to care for the whole human person, body and soul. She trained at the Pope Paul VI Institute and became a Medical Consultant for NaPro technology in April 2011. She is Fellow of the American College of Obstetrics and Gynecology, a Fellow of the American College of Surgeons and a member of the American Association of Pro-life Ob/Gyns. She and her husband, Jack Reybold, reside in Catonsville.

Lisa Gesterling, MS, CNM, WHNP-BC

Lisa Gesterling is a board-certified nurse midwife and women’s health nurse practitioner. She completed her Bachelor of Arts in Anthropology from the University of Colorado-Boulder, before receiving her Bachelor of Science in Nursing from the University of Colorado-Colorado Springs. She then earned her Master of Science in Midwifery and Women’s Health from Georgetown University, and was inducted in the Sigma Theta Tau International Honor Society of Nursing.

Before joining Natural Fertility Care, Lisa worked in the medical -surgical, cardiac and women’s health. She quickly fell in love with obstetrics and women’s health. As part of her commitment to promoting women’s health, she became a Marquette Method natural family planning instructor. Natural family planning plays an important role in her practice, as a family planning method and as a gynecological screening tool. Her clinical expertise in natural family planning better equips her to provide holistic, evidence-based care for the women she serves.

Out of the office, Lisa enjoys hiking, paddle-boarding, and playing board games with her family.
