Bringing half a century of experience to serve the insurance needs of families and businesses locally and beyond.
50 years of history.
Walter Mark Agency Inc. has a storied history that goes back to our founding in 1973. Walter Mark, who had joined Erie Insurance in 1957, carried on that relationship to form a family-owned and operated agency that is still here today and is stronger than ever. Now owned by Walter’s son, Eric Mark, along with his sister, Lisa Mark Cerenzia, the two bring over 50 years of insurance experience to the table. Our team continues to work from our local office—a colonial-style house built in 1857, a symbol of where we’ve been and our stability moving forward.
Dedicated to service with a personal touch.
As a local, independent insurance agency, Walter Mark Agency Inc. has continued our tradition of putting the service of others first, treating others as we would want to be treated. The Golden Rule has been a guiding principle of ours from the start, and it’s something that shows in how we interact with each of our clients. We take every opportunity to thank our current clients for entrusting us with serving their insurance needs, and we look forward to helping you with yours next.
Expanding our horizon.
In 2023, we merged with Colaizzo Thompson Insurance Associates—an agency that has been providing insurance solutions for over 30 years. 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.
Walter Mark Agency Inc. is centrally located in Canonsburg, PA, and we are proud to serve families and businesses in Pittsburgh, PA, Southwestern Pennsylvania, and across five states with the same local service with a personal touch.
At Walter Mark Agency Inc., our family-owned business has been focused on serving the insurance needs of local families and businesses for 50 years—we look forward to 50 more years of service and beyond.
