  • Mayo Clinic
  • Stanford University
  • Washington University in St. Louis

Many of our physicians have also received additional training in advanced endoscopic procedures, intensive exposure to specific diseases, and developed special interests, thereby allowing our Center of Excellence to provide the comprehensive care you would expect from a large university center, with the convenience of being close to home.  Our advanced nurse practitioners utilize their extensive clinical experience to care for our patients in either the office or hospital settings.
Our History
Established in 1975, by Dr. Roger Greenlaw our original office was one of the first office based diagnostic endoscopy labs in the United States.
