The mission of AIG is to provide superior and comprehensive diagnosis and treatment in the kindest, most compassionate manner possible. The doctors and physician extenders use a patient-centered approach to care, aimed at building positive relationships based on trust and mutual respect.

With a focus on preventative medicine, the group offers a full range of endoscopic procedures and screenings for colon cancer as well as treatments for gastrointestinal disorders such as gastroesophageal reflux (GERD), irritable bowel syndrome (IBS), and inflammatory bowel syndrome (Crohn’s disease and ulcerative colitis). More advanced procedures include endoscopic ultrasound (EUS) and endoscopic retrograde cholangiopancreatography (ERCP) to diagnose and evaluate gastrointestinal cancers and treat pancreatobiliary disorders, radiofrequency ablation (RFA) to treat Barrett’s esophagus and reduce the risk of esophageal cancer, and capsule endoscopy to diagnose disorders of the small intestine. The practice also offers banding to treat hemorrhoids.
