—   Embracing the Past while Building for the Future   —

Since its founding, Peter Shannon & Co. has been dedicated to providing clients with professional services of the highest quality.  Maintaining the highest standards of excellence begins with outstanding individuals.  Virtually all of our accounting staff hold or are working toward advance degrees and/or professional designations, and many of them have several years of specialized experience.

Our mission is to provide professional service that consistently exceeds the expectations of our clients.  Technical competence alone is not sufficient to meet client expectations.  Quality service is expected.  We commit to open communication and timely responses to our clients throughout the year, not just during the times of peak accounting activity, so that we can properly address any concerns and ideas.  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.  We also provide services to organizations such as golf courses, unions,  and other non-profit agencies.  Many of our clients have been with us for twenty, thirty, and some in excess of sixty years.  Peter Shannon & Co. is a firm with a history and reputation we are proud of; a firm that many of our fine clients are pleased to work with on project after project.
