Founded in 1927 by John D. Westra, SIA has been a family owned agency serving Waupun and the surrounding area for over 80 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 offices in 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.

SIA Insurance Services is a full service independent insurance agency. We will review your needs, analyze your risks, explain the options and offer solutions to your problems.

Mission Statement:
We will provide peace of mind for our customers by exceeding their expectations in the products we offer, the service we provide, the value they receive and the relationships we share.
