Hartford, WI

R.S. Semler Insurance, an Affiliate of Robertson Ryan, has proudly served Southeastern Wisconsin for over 50 years.

Our agency’s story began in 1968 when Robert Semler took over the business from his father-in-law, Wilmer Lau. Over the years, the agency’s name evolved, but the focus on trusted relationships and personalized service remained the same.

Craig Semler, Robert’s son and the third generation in the business, began working at the agency in 1985 and later joined full-time. Together, Craig and Robert served clients for decades and continued building on the family legacy.

In 2019, we affiliated with Robertson Ryan Insurance, one of Wisconsin’s top independent agencies. This connection strengthened our offerings while allowing us to remain rooted in the community.

Based in Hartford, Wisconsin, we believe people come first. Whether you’re looking for personal or business insurance, our team is here to guide you with care and experience.

We proudly serve clients across Southeastern Wisconsin, including Hartford, Slinger, Rubicon, Jackson, Richfield, Oconomowoc, West Bend, Iron Ridge, Horicon, Neosho, Germantown, Hubertus, Kewaskum, West Allis, Milwaukee, Menomonee Falls, Hartland, Allenton, Hustisford, and Ashippun.
