Our staff places a high priority on working closely with clients, listening carefully, and helping them to define future needs and opportunities. Due to our history and commitment to the quality of our work, we are one of the most highly regarded accounting organizations in the Chicagoland area. Since our company's founder, Peter M. Shannon started his accounting business, our client list has grown considerably to include many well-known private and public institutions. Our clients are in a variety of industries including construction, medical, trucking, manufacturing, retail and wholesale, as well as various service fields.
