He received his medical degree at Des Moines University College of Osteopathic Medicine in 1980.

He is board certified in both internal medicine and gastroenterology.

Dr. Coates’ clinical interest include 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 treatment to patients who otherwise could not have afforded or received such care.

While a principal investigator at West Michigan Clinical Research Center, he has participated in a number of studies and he has participated in studies for a number of gastroenterology conditions, including GERD, nonulcer dyspepsia, hepatitis C, Crohn’s disease, ulcerative colitis, and irritable bowel syndrom. As a result of his involvement, a large number of patients from the West Michigan Clinical Research Center were recently enrolled in a clinical trial for a new treatment for irratble 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.
