“Providing thorough and thoughtful care begins with attentive listening to a patient’s concerns, discussing their preferences and goals, and determining the best treatment plan for each individual patient. No two people are alike and different approaches are often successful in achieving good health.”
Dr. Duman completed his undergraduate degree in biology at the University of Texas at Austin. He received his medical degree from the University of Texas Health Science Center at Houston and was accepted into the national medical honor society, Alpha Omega Alpha. He completed his three-year internal medicine residency, as well as a three-year gastroenterology fellowship at the University of Colorado Health Sciences Center.
