OUR HISTORY

WE REPRESENT THE MOST INNOVATIVE PRODUCTS

IN THE PLUMBING INDUSTRY

Bill Davenport and John Kaczmarczyk founded D&K Sales Company in 1980. Bill started his career at Great Lake Sales in Cleveland, Ohio in 1971. Working with his dad, Frank “Davvy” Davenport, he learned the manufacturing rep business for the next 9 years when he was offered the Delta Faucet Company line in Kansas and Western Missouri. Bill asked John to join him in this new adventure and moved to the Midwest in 1980. Bill was located in the Kansas City area and John was located in Wichita, KS. After hiring a new outside salesman in Wichita, John moved to Kansas City in 1984. Bill & John were introduced to Paul Zeller in 1990 when they were hired to become the representatives for Woodford and Watco Manufacturing. Paul Zeller became a partner with Bill and John and the company was renamed to Summit Sales Inc.

In 2006, Delta Faucet Company asked Summit Sales to expand into St. Louis by adding eastern Missouri and southern Illinois to their territory. With the addition of the new territory, Darcy Sappingfield and Marty McNee became partners in 2007. Summit Sales has grown significantly with the addition of Fluidmaster in 2008, Milwaukee Tool in 2012, Insinkerator and Maax Bath in 2015, Toto in 2018 and Viega in 2020. 

Summit Sales currently has 16 employees with an office in Olathe, KS. We have outside sales reps living and working in the major markets of Wichita, KS, Springfield, MO and St. Louis, MO.
