About Us

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.

What is an Independent Insurance Agent?

When you decide to buy a car, you wouldn’t purchase the first one you see. What if one day the automobile industry decided to make only one type of car, one make and one model. You wouldn’t have a choice!

The same situation holds true for insurance. You need insurance to drive a car, to purchase a house, to protect your family’s financial future and to run a small business. But if there was only one insurance company that offered only one type of insurance, car insurance, home insurance or business owner policy — you wouldn’t have a choice. The only solution would be going to that one company.

With an independent insurance agent, you have choices. Independent agents are not tied to any one insurance company. One of the advantages of using an independent agent is that he or she works to satisfy your needs. You are using an expert for an important financial decision.

An independent agent has several companies that he or she can approach to get you the best coverage at the best price. And your independent agent will know the companies with the most efficient claims departments to recover your losses as quickly as possible.

When you buy insurance, whether it’s for your home, your car or your business, you want an advocate who will properly assess the risks you face and give you an objective analysis of the marketplace, it’s up to you to make the final choice.
