In 2000 Michigan State University gastroenterology divisions from the College of Osteopathic medicine and Human medicine joined Digestive Health Institute to combine clinical and educational forces. This unique relationship was coordinated to improve patient care, enhance education, and advance research in the area of gastroenterology.
To the best of our knowledge, a university and private practice have never undertaken this type of arrangement. All the physicians at Digestive Health Institute are affiliated with Michigan State University. We are involved with the education of medical students at the College of Osteopathic Medicine and the College of Human Medicine. We also train interns and residents at Ingham and Sparrow Hospitals.
Patient care is our priority, and with this affiliation we supply top-quality progressive patient care for mid Michigan.
