About Me

Conditions I specialize in
  • Gastroenterology

With more than 17 years of experience as a gastroenterologist, medical director and assistant professor, Dr. Stephan Dehmel is a board-certified gastroenterologist with a special interest in inflammatory bowel disease and irritable bowel syndrome. His interest in medicine began with his parents and grandparents, who were involved in the medical field.

Dr. Dehmel sees patients for cancer screening and a variety of gastrointestinal and liver diseases. He believes in a holistic approach to medicine rather than focusing on medications. He likes to get to know his patients, believeing that learning more about their lives will help determine the best course of treatment. He also emphasizes prevention to help people live healthy lives through essential screenings, including colonoscopies and endoscopies. Dr. Dehmel encourages everyone to eat a balanced diet with fruits and vegetables, while avoiding processed foods.
