Born in Miami, Florida, Major Andrew S. Thagard joined the Air Force through the health professions scholarship program in 2004 while a senior in the College of Science at the University of Notre Dame where he graduated cum laude. He earned his medical doctorate in 2008 at the University of Florida College of Medicine before completing an internship and residency in Obstetrics & Gynecology at Naval Medical Portsmouth from 2008-2012. While a resident, Thagard distinguished himself by serving six weeks aboard the USNS Comfort in support of Operation Continuing Promise providing gynecologic surgical care to women in need throughout Latin America.

Upon graduation from residency, Thagard remained at Portsmouth for a year serving as a staff specialist in Obstetrics & Gynecology in addition to a three month stint providing critical support in women’s health services at Naval Hospital Jacksonville. In addition to his clinical duties, he served as chair of the hospital’s ORYX Perinatal Advisory Committee and provided educational support for the Department’s residency program. He was accepted to a fellowship in Maternal-Fetal Medicine at Madigan Army Medical Center starting in 2013. As a perinatology fellow, Thagard provided high acuity care to the pregnant population of Joint Base Lewis-McChord and Naval Station Bremerton. He was recognized as a prolific researcher, establishing a mouse research platform to explore the impact of preterm labor on the neurodevelopment of offspring that culminated in three publications and ongoing hypothesis generation. He secured over $300,000 in research grants and presented his findings at regional and national meetings. His collaborative efforts with researchers at Johns Hopkins continue to this day.

After completion of fellowship, Thagard returned to Naval Medical Center Portsmouth where he continues to serve as a staff physician in the Division of Maternal-Fetal Medicine. His focus remains on education, standardization, communication, and collaboration to improve outcomes for the patients he serves. To these ends, he created a Maternal-Fetal Medicine outreach clinic at USAF Hospital Langley and designed and implemented a protocol to optimize the care of pregnancies complicated by growth restriction. Thagard is recognized as a core faculty member of the OB/GYN residency program and is the site director for medical students rotating through the Women’s Health Department from the Uniformed Services University, Eastern Virginia Medical School, and a variety of other civilian institutions, mentoring students, interns, and residents in research. He is an ardent supporter of simulation in medical training, serving as faculty for the annual Society of Maternal-Fetal Medicine Obstetrics Critical Care Course. At a national level, he is the vice chairman of the Armed Forces Maternal-Fetal Medicine Network and chairman of the DHA WICC's Opioid & ERAS Working Group.

Thagard was first certified by the American Board of Obstetrics & Gynecology in 2014. He is a fellow of the American College of Obstetricians & Gynecologists and holds active membership in the Society for Maternal-Fetal Medicine, the International Society of Ultrasound in Obstetrics & Gynecology, and the American Institute of Ultrasound in Medicine. His personal awards include the Meritorious Service Medal, Air Force Commendation Medal, Army Achievement Medal, and National Defense Service medal.
