TDA Insurance & Financial is a family owned independent insurance agency that offers home, auto, business, life, and health insurance, as well as financial services. Mark and Sherry Diederich started the business as a nationwide agency in Novi in 1996. In 2010, we transitioned from a Nationwide agency to an independent insurance agency, which allows us to use 12+ insurance companies rather than just one. In March of 2018, we moved our office from Novi to Walled Lake. We are extremely happy with our new location. We have three Walled School high school graduates on our staff: Sherry Diederich, Anthony Finn, and Kelly Finn. Anthony and Kelly still live in the Walled Lake area, and Sherry's son Dan, who is also on the staff, lives on Wolverine Lake. Our business model is based off the question: how would we want our insurance to be handled both as a family and a business? Luckily, we have experience in both regards. The ultimate goal is to have our family help protect yours, and for everyone we interact with to have a GREAT DAY AT TDA!
