Dennis L. Keller, Fortified with the Sacraments of Holy Mother Church on Friday June 5th, 2026. Dennis, 85, was born in St. Louis, Missouri. He was a loving and devoted man whose family meant everything to him. He was a machinist for all of his working life, retiring from Anheuser-Busch many years ago.
An avid and self-taught DIY-er, Dennis enjoyed working on home-improvement projects at his own home, and at those of family and friends. In his spare time, he enjoyed fishing, boating, bowling, pitching horseshoes, and especially spending time with family at the Lake.
