SIA Insurance Services

Founded in 1927 by John D. Westra, SIA has been a family owned agency serving Waupun and the surrounding area for almost 100 years. Today we still have our main office in Waupun and we still have family ownership. We now service accounts throughout the state, as well as their out-of-state operations. We have expanded our business to include agents in Randolph, Jackson, and Greenville, and we are looking forward to continued growth, through the reputation we have established for insurance value and customer satisfaction. Over the years, we have established long-term relationships with the companies we represent and the customers we are privileged to serve. These are the relationships upon which SIA Insurance Services has been built.
