Gerald W. Culkin

Gerald W. “Jerry” Culkin, 71, of Denton, Texas, passed away peacefully on May 30, 2026, surrounded by the family he so deeply loved.

There are some people whose presence changes the atmosphere around them, whose lives quietly illuminate the path for others. Jerry was one of those people.

A man of deep faith, profound intellect, unwavering integrity, and genuine humility, Jerry lived his life as a witness to Christ’s love, mercy, and grace. He did not simply speak about faith; he lived it authentically and unapologetically through service, compassion, generosity, and the way he treated every person he encountered. To his family, friends, colleagues, and fellow parishioners, he became a steady beacon of wisdom, kindness, and hope.

Born on June 4, 1954, in Chicago, Illinois, Jerry was the eldest child of Joseph and Margaret (Morgan) Culkin. Due to his father’s career with the FBI, his childhood took him to Hammond, Indiana; Daytona Beach, Florida; and Cincinnati, Ohio.

From an early age, Jerry was drawn to both adventure and service. As a Boy Scout, he earned the rank of Eagle Scout, embodying principles of leadership, responsibility, and selflessness that would define the rest of his life. He remained an avid outdoorsman throughout his years, finding joy and renewal in backpacking, camping, whitewater kayaking, and sharing his love of the outdoors with his children and grandchildren. Whether on a hiking trail, a river, or in his own backyard, Jerry delighted in helping others discover confidence, wonder, and joy in God’s creation.

He graduated from Finneytown High School in Cincinnati in 1972 and briefly attended the Air Force Academy before earning a Bachelor of Science degree in Chemical Engineering from the University of Cincinnati in 1976. His lifelong pursuit of learning led him to the University of Texas, where he earned his Master’s and Ph.D. in Environmental Engineering in 1989.

He worked for Goodyear from 1977 to 1984 before pursuing doctoral studies and later teaching Chemical Engineering at Old Dominion University. Returning to Goodyear in 1992, Jerry spent the remainder of his career serving in leadership roles including Chemical Material Safety Manager and Lean Six Sigma Master Blackbelt Principal before retiring in 2019.

Jerry possessed the rare combination of a brilliant analytical mind and a deeply relational spirit. Though accomplished professionally as an engineer, professor, and leader, he approached life with thoughtful curiosity, humility, and a genuine desire for continuous improvement. This pursuit extended not only to systems and processes, but also to himself and how he could better serve God and others.

Retirement gave Jerry even more opportunity to pour himself into the people and causes he loved most. He and Carol treasured traveling together and embraced every opportunity to spend time with their children and grandchildren, whether helping with home projects, babysitting, attending performances and celebrations, or simply being present for the ordinary moments that mattered most. His family never doubted their place in his priorities, and his steady presence remains one of his greatest gifts to them.

Jerry was deeply devoted to the Catholic Church and gave generously of his time through numerous ministries and service organizations. He sang proudly as a tenor in the church choir, participated in men’s Bible study, advocated tirelessly for the dignity of every human life through the Respect Life ministry, helped provide food for families through the Bread of Life ministry, found deep fulfillment supporting U.S. Special Forces families through The Station Foundation in Montana, and served rural communities in El Salvador through Living Water.

Jerry understood faith not as something abstract, but as something lived through action, mercy, presence, and love.

He also found deep joy in music, especially playing trumpet and singing. Music was the backdrop of Jerry’s life; rarely was there a moment without thoughtfully chosen songs filling the background of everyday life, long drives, family gatherings, or quiet evenings at home. He shared with his family not only a love of music itself, but an appreciation for its power to stir emotion, create connection, inspire reflection, and draw the heart toward praise and gratitude.

Jerry also carried with him a deep appreciation for his Irish heritage, storytelling, and meaningful conversation. He was both contemplative and deeply engaged, equally at home discussing theology, engineering, philosophy, music, or simply connecting with someone who needed to be seen or heard.

But above all else, Jerry loved his family.

He and Carol Marks were married in 1981 and built a beautiful life together over 45 years marked by faith, perseverance, sacrifice, laughter, and devotion. Their journey together carried them across the country, including Akron, Austin, Virginia Beach, Beaumont, Hudson, Houston, and finally Denton, as Jerry pursued his education, teaching career, and professional work. Through every season of life, Jerry remained a devoted husband and a steady, loving father whose wisdom and encouragement shaped generations.

Left to carry forward the light of his love for God and family are his devoted wife, Carol; his loving children Katy Lee (Jeff), Colin (Lindsay), and Patrick; and his cherished grandchildren Benjamin, Jacob, Avery, Josie, Charlie, Ellie, Lincoln, and Scarlett. He is also survived by his sister Mary Ortman (Michael).

He was preceded in death by his parents, Joseph and Margaret Culkin, and his brother James Culkin.

An opportunity for visitation will take place from 5:00 to 7:00 p.m. at Bluebonnet Hills Funeral Home. Funeral services will be held on Saturday, June 13, at St. Mark Catholic Church, with a Rosary Vigil at 9:30 a.m. followed by Mass at 10:00 a.m. The family invites all who knew and loved Jerry to join them for a reception in the parish hall following Mass. A graveside service and interment will take place at Daytona Memorial Park in Florida on June 21, at 10:00 a.m.

Jerry’s life reminds us that greatness is often found not in recognition or status, but in quiet faithfulness, in choosing day after day to love God, serve others, pursue truth, and care deeply for the people entrusted to us.

His life was his witness, and that witness will continue to shine in all those who were blessed to know and love him.

In lieu of flowers, the family suggests donations be made in Jerry’s honor to a charity close to his heart.
