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.

A convert to Catholicism, he set an example of faith for his family to follow. He was a 4th degree Knight of Columbus. He will be fondly remembered for his huge heart, his willingness to lend a helping hand to anyone in need, and the joyful laughter that lit up his entire face.

Dennis became like a family member when my brother, Christopher, shared his room at Nazareth McGovern House. He was very kind and always had a smile and a Hi for us when we visited. He shared Maureen with Christopher for many months. These two (Dennis and Maureen) are a great joy in my family life. I am so thankful to have met them and shared our time at McGovern House. Peace to you all at this difficult time. 🙏🫂✝️ Jeanne Cross
Jeanne, thank you for your beautiful words and for our friendship forged “in the trenches.”Christopher, was a wonderful person, and it was my pleasure to know him and find friendship with you all, his equally wonderful family. God bless you.
Uncle Dennis was such a kind man. I’m glad we got to catch up at my dad’s party. Our hearts go out to all of you during this time of sorrow. I hope that all your wonderful memories can provide some comfort to you. Thinking of all of you. Please know that we send our love, prayers and support.
Dennis was a wonderful human being with a giving and loving heart! Our friendship began when he met and dated and then married my best friend, Joyce. Though living in different sides of the country, our lives intertwined through the years with phone calls and visits. We were blessed to have visited with Dennis and his family last year. May his memory be a blessing and bring peace and a smile to your hearts.
Uncle Dennis was a kind man. He always had a smile and welcomed us into his home. We’re so sorry to hear of his passing. I’m glad that we were able to catch up at my dad’s birthday party. Thinking & praying for all of you during your time of sadness.
