Dennis grew up with his brothers in the water well business in Clara City, MN. Summer Mondays typically meant traveling to a drill-site with an older brother or hired man to work for the week. In the early 1960s, he married Marge and they established the Rochester branch of Thein Well Co.

An innovator, Dennis holds several patents in the water well industry, is a certified Master Water Well Contractor and was the first in the area to invest in Rotary well drilling equipment - drilling wells in days instead of weeks.

Dennis and Marge now spend the majority of their time enjoying the sunny skies and warm temps of Naples, Florida.
