Daniel F. Losiniecki

Dan Losiniecki, of Oak Creek, Wisconsin, passed away peacefully on April 28, 2026, at the age of 88.

Preceded in death by his beloved wife, Patricia, as well as his parents, Walter and Regina Losiniecki, and his siblings Joseph, Kenneth, Leonard Losiniecki, and Theresa Birnbaum.

Dan is survived by his children: Karen (Christopher) Phelps, Peter (Mary Kay), Richard (Mary Ellen), and David (Teresa) Losiniecki. Proud grandfather of 13 grandchildren and 8 great-grandchildren. Also survived by his brothers Thomas (Geraldine) and Ralph (Jeanne), and his sister Maryann Vesper. He will also be dearly missed by other family and many friends.

Dan proudly worked at Allen-Bradley Rockwell Automation in the model shop as a Master Model Maker for 39 years. In 1993, he and Pat achieved their dream of owning a lake home in Eagle River, WI. The Catfish Lake house was where he and Pat shared 20+ years of joyful memories with their children, grandchildren and friends. He taught every grandchild how to fish, took all on many cruises of the chain and ended every night with a campfire, sitting on his swing with Pat under the stars. This was their piece of heaven for sure. Dan was a gifted craftsman, and he made many improvements on his lake home. He also spent time helping his kids with numerous home improvement projects. Dan had the gift for conversation and truly enjoyed connecting with people, whether on Waterman Lane, Fitzsimmons Rd, at St. Matthews or wherever he went. His St. Matthews extended family was very important to Dan, and he proudly spoke of his special memories made with his dear church friends.
