InterGroup Services established its first provider network over 25 years ago in southeastern Pennsylvania and has grown steadily since that time. InterGroup’s PPO covers Pennsylvania, New Jersey and Delaware as well as parts of West Virginia, Ohio, New York, and Maryland. As our provider network has grown, so has our client base. We are one of the largest PPOs in the Eastern U.S. and are continuing our strong growth across the region. We at InterGroup Services value the concept of working partnerships in which “win-win” situations are developed. Much of our success over the past several years is a direct result of our adherence to the belief that simple, direct communications between partners creates these situations.
