Cooper Trost, MD, is a compassionate, board-trained OB-GYN at Holy Cross OBGYN in Mesquite, Texas. His path to obstetrics began when he became a father—an experience he considers both his greatest accomplishment and most challenging role. That journey sparked a deep passion for pregnancy, childbirth, and women’s health, ultimately leading him to a career where he could support patients through their most meaningful and sensitive moments.
Raised just outside Portland, Oregon, Dr. Trost earned his bachelor’s degree in human biology from BYU–Idaho and completed his medical degree at Kansas City University in Kansas City, Missouri. He went on to complete his OB-GYN residency at Wright State University in Dayton, Ohio, where he served as Chief Resident at the Five Rivers Center for Women’s Health. During training, he received the prestigious AAGL Minimally Invasive Gynecological Surgery Award, recognizing his skill in advanced, patient-centered surgical care.
Dr. Trost’s clinical interests include preconception counseling, contraception, high-risk pregnancy management, patient-centered labor and delivery, and minimally invasive gynecologic surgery, including Da Vinci robotic-assisted procedures. He is committed to helping women make informed decisions and supporting them with empathetic, evidence-based care.
Now settled in the Dallas–Fort Worth area with his wife and two young sons, Dr. Trost is thrilled to join Holy Cross OB-GYN. He looks forward to serving patients in Mesquite, Terrell, and Rowlett and building long-term partnerships that empower women to live healthy, confident lives.
