Maria Esposito, M.D.

Colonel Maria E. Esposito, M.D., MC, U.S.A.R., passed away peacefully in Maryland on July 30, 2026. Born on January 21, 1939, in New York City, Maria (or Mary, to friends and family) lived a life of extraordinary service, compassion, and purpose. She was a pioneering physician, military officer, educator, mentor, devoted wife, mother, grandmother, and friend whose influence reached far beyond the countless patients, students, and colleagues whose lives she touched.

Mary possessed a quiet strength that inspired everyone around her. She was fiercely determined, deeply loyal, exceptionally intelligent, and unwavering in her commitment to excellence. She earned the admiration and respect of all who knew her for her kindness, integrity, and tireless dedication to medicine, education, and military service.

Mary attended Russell Sage College in New York before earning her medical degree from the University of Bologna in Italy. She completed her internship in Valhalla, New York, and later moved to Germany with her husband, Anthony, who served as a Captain in the United States Army. Upon returning to the States, she practiced as a pediatrician in San Francisco before also answering the call to military service and joining the United States Army. At Walter Reed Army Medical Center, Mary completed her medical training (residencies and fellowships) in Child and Adolescent Psychiatry. She was board certified in Psychiatry, Child and Adolescent Psychiatry, and Neurology.

Mary built a distinguished academic and military career that spanned decades, culminating in her promotion to the rank of Colonel. Beginning in 1980, Colonel Esposito joined the faculty of the Uniformed Services University of the Health Sciences (USUHS), where she became a nationally recognized educator and mentor. As Director of the Third-Year Psychiatry Clerkship, she guided the clinical psychiatric education of approximately 170 medical students each year, shaping the next generation of military physicians with the same compassion, discipline, and high standards that defined her own career. In recognition of her exceptional dedication to medical education, she received the American Psychiatric Association's prestigious Nancy C. A. Roeske Award for Excellence in Medical Student Education in 1994. She was also presented with the Exceptional Service Medal in 1995 from USUHS recognizing her many distinguished years of service at the medical school.Her accommodation stated that “Her distinguished accomplishments reflected great credit upon herself, the Uniformed Services University of the Health Sciences, the United States Army, and the Department of Defense”. 

Colonel Esposito also served as the Residency Training Director at Walter Reed Army Medical Center, where she mentored numerous physicians specializing in psychiatry. Her service left a lasting imprint on military medicine through the physicians she trained.

Colonel Esposito was also a pioneering advocate for women in medicine and military service. She helped develop programs at USUHS dedicated to supporting and advancing the professional development of women medical students, opening doors for future generations of physicians and leaders. Beyond the university, she strengthened ties with the regional psychiatric community through her leadership in the Suburban Maryland Psychiatric Society, serving in roles including Vice President, Treasurer, and Program Coordinator.

Despite her remarkable professional achievements, Mary’s greatest joy was her family. She adored her grandchildren and treasured every opportunity to spend time with them. She loved music (she was a classically trained pianist), traveling the world with her husband and family, discovering new cultures, and sharing a love of cooking and wonderful meals with family and friends, who were always welcomed into her home. Her curiosity never faded; she believed there was always something new to learn and embraced life with enthusiasm, humor, grace, and an open mind.

Mary was preceded in death by her beloved husband of more than fifty years, Dr. Anthony Esposito, who passed away in 2018. Their marriage was a partnership built on love, mutual respect, and devotion to family. She is lovingly remembered by her sons, Mark Esposito, M.D., and his wife, Rieyn DeLony, Esq., and Matthew Esposito, M.D., and his wife, Suzanne Caron, M.D. She was the cherished grandmother of Emma, Benjamin, Francesca, and Caroline Esposito. Her warmth and guidance will also be deeply missed by her brother, Frank Quattromani, M.D., along with her extended family, dear friends, former students, colleagues, and patients who meant so much to her.

Her family finds comfort in knowing that her influence will live on through the generations of physicians she trained, the women she mentored, the patients whose lives she improved. Her family will forever cherish her love, her kindness, devotion and faith that she embodied. A celebration of Mary's life will be announced by the family. In lieu of flowers, the family suggests that donations be made to the Alzheimer's Foundation or the Multiple Sclerosis Society in her memory.
