Providing Leading Gastroenterology Care Since 1978
As early as 1978, our gastroenterology practices have been serving patients with GI conditions across Illinois. A unique vision to deliver excellent patient care, strive for continual quality improvements and outcomes, and provide the most up-to-date treatments attracted the best gastroenterologists in Illinois to form Illinois Gastroenterology Group over 10 years ago. From there, that vision grew into the development of the GI Alliance in 2019. GI Alliance (GIA) is the largest independent gastroenterology practice in the U.S. operating in over 14 states. GIA is a partnership of premier gastroenterology groups across the nation, representing a great heritage of superior gastroenterology care focused on the goal of providing superb patient care and improving the lives of patients with GI conditions.
The GI Alliance of Illinois is comprised of over 70 top-rated board-certified GI physicians. Medical professionals and patients alike trust the gastroenterology expertise of our GI Alliance of Illinois providers. The GI Alliance of Illinois providers are on the cutting edge of gastroenterology care and, through the support of the GI Alliance, have full access to the most extensive body of GI-knowledge.
GIA of Illinois, formerly known as Illinois Gastroenterology Group (IGG), was formed in 2010 through the merger of Elgin Gastroenterology, Lake Shore Gastroenterology, and Northwest Gastroenterologists. Midwest Center for Digestive Health joined IGG in 2011, Gastrointestinal Health Associates of Geneva joined in 2013, and North Shore Gastroenterology joined in 2014. Here is a listing of the groups that share our DNA and now form GI Alliance of Illinois:
