JW Lafrenier Sons

Company Overview

Designing, installing, fixing, and servicing septic systems.

We provide solutions for challenging locations.
Established in the 1930s, J. W. LaFrenier Sons has a rich history. The business was initiated by my grandpa, dad, and two uncles. Len and Lynn LaFrenier acquired the family business in 1988.

As new technologies emerge in the on-site industry, we participate in training to provide solutions for current building codes.
Since high school, Len has been involved with J. W. LaFrenier Sons. While studying at UW Marathon and UW Madison, he spent summers and weekends working for the family business.
Outside of work, Len enjoys scuba diving, hiking, photography, and stargazing.
