We come from a long line of plumbers. My grandfather John Sr. started J Kummer Plumbing & Heating in his garage back in 1949. Building a proper shop in Sheboygan WI in 1957. My father Jr. and uncle Walter signed up to work for grandpa to work for many years. My father took the reigns to continue the service in 1976. My bother John signed on in 1979 and I, Michael, signed on in 1983.

I left the family business in 2000 to work for Jacks Plumbing Service, my father and uncle closed shop as they were bought out in 2001.

I have since purchased Jacks Plumbing Service in 2015 and brought back the family name of J Kummer Plumbing. In 2013 my son John has joined me to continue on the legacy.
