An Independent Advantage
We are Independent Agents in Waupun, Wisconsin, free to choose the best carrier for your insurance needs. We do not work for an insurance company; we work for you. We work on your side when you have a loss and follow through to see that you get fair, prompt payment and service. SIA Insurance Services represents a carefully selected group of financially strong, reputable insurance companies, therefore, we are able to offer you the best coverage at the most competitive price.
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.
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.
