J. W. LaFrenier Sons was founded in the 1930s. My grandfather, father, and two uncles started the business. 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.
Len has been part of J. W. LaFrenier Sons since his high school days. While attending UW Marathon and UW Madison, Len worked for the family business during weekends and summers.
In his free time, Len engages in scuba diving, hiking, photography, and studying the stars.
