Dr. Allan Coates


Dr. Allan Coates has been a principal investigator at WMCRC for over 25 years. He received his medical degree at Des Moines University College of Osteopathic Medicine in 1980. He completed his residency in internal medicine at Metropolitan Hospital in Grand Rapids and his gastroenterology fellowship at the University of Michigan in Ann Arbor. He is board certified in both internal medicine and gastroenterology.

His clinical interest includes gastroesophageal reflux disease, esophageal motility disorders, inflammatory bowel disease and chronic liver disease.

He believes that all patients should be treated with respect and compassion, and that everyone has access to quality health care. His involvement in clinical research has allowed him to bring new and innovative treatments to patients who otherwise could not have afforded or received such care.

He has participated in a number of studies for gastroenterology conditions, including GERD, non-ulcer dyspepsia, hepatitis C, ulcerative colitis, and irritable bowel syndrome. He recently had a number of patients enrolled in a clinical trial for irritable bowel syndrome that was published in the New England Journal of Medicine.

Dr. Coates and his wife Sharyn enjoy travel, gardening and spending time with their five children.
