Jean Sergo Valcourt, MD

Dr. Jean Sergo Valcourt, 74, of Centerville, GA, passed away on the evening of Sunday, November 30, 2025 peacefully at home. He was born in Haiti to the late Athanase Valcourt and Anne-Marie Valcourt, and was one of thirteen siblings.

Serge grew up in Haiti and pursued his education with deep commitment. His dedication to learning and service shaped every step of his life’s journey.

After attending Collège Canado-Haïtien and graduating from Université d’État d’Haïti, he completed his pediatric residency training in Port-au-Prince, then practiced as a pediatrician in Haiti before moving to the United States in 1984. Upon arrival to the states, he dedicated himself to to pursue advanced medical training as an internal medicine physician in New York.

Driven by his insatiable thirst for knowledge, he later on went on to specialize in Nephrology at Mount Sinai hospital in New York. 

He served his community as a respected Nephrologist and Hospitalist, caring for countless patients with these exceptional and robust skill sets, with compassion, and professionalism, and humility.

A devout Seventh-day Adventist, Serge faithfully served his church communities for many years, acting as both elder and first elder in several congregations. 

Serge was an intellectual in every sense who breathed and lived for medicine—deeply thoughtful, disciplined, brilliant, thorough and guided by his unwavering faith and passion for caring. 

He loved reading his Bible, listening to gospel and classical music, and engaging in heartfelt, insightful conversation.

He will be most remembered for his profound passion for education and his meekness. To Serge, learning was both a privilege and a responsibility, and he instilled that belief deeply in his children. They often recall his conviction that excellence was the standard, where a grade below 90% simply reflected untapped potential. His unwavering encouragement inspired each of them to pursue higher education to the fullest extent of their abilities.

He is survived by his wife, Mireille Valcourt, RN, BSN and his four children: Erica Lee Valcourt , MBA; Dr. Lindsey Sergina Gibbs RN, BSN, PHD (nurse anesthetist), with her husband Terrell Gibbs, RN, BSN; Stacey Johanne Valcourt RN, NP-BC; and his son, Justin David Severe-Ellis. He also leaves behind his cherished grandson, Hunter Edward Gibbs.

He will be profoundly missed by his family, friends, colleagues, church community, and all who were blessed to know him. Those who knew Serge will remember his quiet strength, his love of Scripture, his family, traveling and his unique passion for the profession he loved so much: medicine!

His legacy of faith, service, and love will continue to live on in the many lives he had touched.
