In 2023, Colaizzo Thompson Insurance Associates merged with the Walter Mark Agency.
Expanding our horizon.
Both the Walter Mark Agency and Colaizzo Thompson Insurance Associates have been serving Canonsburg and the surrounding area for over 50 years. Now that our agencies have merged, we continue to operate as an independent insurance agency that partners with Erie Insurance. With our combined insight, knowledge, and experience in the insurance landscape, we strive to carry on the legacy of both agencies as we move into the future as one.
