Marissa N. Blair, CNM

After receiving a Bachelor of Science in Nursing from Virginia Commonwealth University, Marissa earned a Master of Science in Nursing from Old Dominion University and a Post-Master's Midwifery Certificate from Shenandoah University. She is board-certified by the American Midwifery Certification Board.

Fascinated with the birth process for her entire life, Marissa spent the majority of her 20 years of nursing practice in obstetrics before becoming a Certified Nurse Midwife. She is addicted to that moment when parents first see their babies.

From prenatal care to delivery, postpartum care and contraception counseling, Marissa values her patients' time and strives to make the most of each visit. She approaches her practice with the philosophy that, for most women, pregnancy is a normal, healthy life process—not a disease to be treated. Her goal is to empower women to embrace the physiologic changes of pregnancy and to trust their bodies.

Originally from Northern Virginia, Marissa met her husband Ken—an Eastern Shore native and emergency room Nurse Practitioner—in college at VCU. The couple loves to watch their son play baseball and spend summer days at the beach or on their boat. Marissa not only loves caring for women of the Eastern Shore, but also finds the area an amazing place to live.
