Independent Insurance Agency - Walled Lake, MI

TDA OfficeAfter 20 years of being located in Novi, TDA Insurance and Financial has moved to its new home of Walled Lake. The new office is located right across the street from Walled Lake’s famous “Woody’s On the Trail,” and just a short walk from Mercer Beach and downtown. 

Although TDA is new to Walled Lake, our staff is no stranger to the area. President, Sherry Diederich, lived in Walled Lake and graduated from Walled Lake Western high school. Dan and Matt Diederich learned how to fish on Wolverine Lake and learned how to hit a baseball at the Copper Mug batting cages. Sales Associate Anthony Finn and CSR Kelly Finn have both lived in Walled Lake their whole life, and graduated from Walled Lake Central High School. The rest of the staff is becoming more and more familiar with Walled Lake as we explore and share our favorite spots around town.

We are excited to be a part of the Walled Lake community. We hope that we can be a one stop shop for all of your insurance needs. Below is a list of the services we provide:
