Dennis Deyoung

Dennis Eugene DeYoung, a devoted family man and accomplished heavy equipment operator, passed away at his home on Monday, April 24, 2023, at the age of 66. Born on July 11, 1956, in Plainville, Kansas, Dennis was the son of Stanley Calvin and Betty Jean (Osborn) DeYoung.

Dennis's life journey was marked by dedication, service, and a love for his family and country. He proudly served in the United States Army, a testament to his patriotism and commitment to protecting the freedoms we hold dear. His military service was a reflection of his character – steadfast and unwavering.

In his professional life, Dennis carved a path as a self-employed heavy equipment operator in both the land field and oilfield industry. His skills and expertise were evident as he took on various projects, including working for Pan-Am Construction in Africa during the late 70s and early 80s. He operated heavy equipment in places like Liberia and Kenya, showcasing his adaptability and competence in his field.

Dennis's heart was forever touched when he married Diane Elizabeth Geist on August 17, 1984, in Hays, Kansas. Together, they created a life full of shared experiences and cherished memories. However, life presented its challenges, and he experienced the profound loss of Diane on May 2, 2017, leaving a void that could never truly be filled.

Dennis found solace and joy in his passions. An ardent sports enthusiast, he took great pleasure in watching the OU Sooners and was an avid supporter of the LA Rams. Fishing provided him with moments of tranquility and reflection, allowing him to connect with nature and find peace amidst life's busyness.

Family remained at the core of Dennis's life. He leaves behind a legacy of love in his son, Calvin DeYoung of Damar, Kansas, and his daughter, Renee DeYoung of Great Bend, KS. He was a caring brother to three sisters: Terri (John) Richardson of Clairmont, NC; Janice (Dennis) Craven of Wichita, KS; and Janet (Mike) Bruna of Plainville, KS. Dennis cherished these relationships and the bonds they shared.

As he moves on to his final rest, Dennis is reunited with loved ones who have gone before him. He joins his parents, his beloved wife Diane, his infant daughter Elizabeth, and his nephew Adam Bruna in eternal peace.
