Luis DeLeon Usuga, MD, is a board-certified obstetrics and gynecology specialist and founder of Dr. DeLeon's Woman's Health Care, a wellness and obstetrics center in Rowlett, a northeastern suburb of Dallas, Texas. Dr. DeLeon began his journey to his medical career more than three decades ago in Medellin, Colombia, at the University of Antioquia, where he earned his medical degree and received surgical training, graduating with honors. He continued his postdoctoral clinical training with an internship at Jackson Health System in Miami, Florida.
Dr. DeLeon then went on to complete two residencies, an obstetrics and gynecology residency at the University of Puerto Rico-School of Medicine, and a general surgery residency at Mercy Fitzgerald Hospital in Darby, Pennsylvania. In addition to serving his patients, Dr. DeLeon mentors future doctors as a preceptor. He’s active in many medical and professional organizations, including the American College of Obstetricians and Gynecologists, the American Medical Association, Dallas County Medical Society and the Texas Medical Association.
Despite his busy schedule, each year Dr. DeLeon organizes an annual medical mission to Colombia as part the Latin America Medical Assistance, a non-profit he founded and also serves as president. Dr. DeLeon is also founding board member of the North Texas Latin American Physicians Association, which was originally established to provide scholarships to North Texas Latin American medical students.
In his free time, Dr. DeLeon enjoys spending time with his wife Maria, his longtime practice manager, and their children.

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.
