Christoph L. Keller

Christoph Loren Keller, a devoted and loving husband, a proud father, and grandfather, passed away peacefully with his family by his side on Monday, January 5, 2026, at the OSU James Hospital after a major complication from surgery at the age of 57. Christoph was born on March 6, 1968, in Würzburg, Germany to his loving parents who he is survived by, Karl and Dianna Keller.

Christoph is also survived by his devoted wife of almost 29 years, Tonya (Schlechty) Keller; his children, Sierra (Brett) Lavy and Landon Keller; his granddaughter, Lainey Lavy; his brother, Josh (Diane) Keller, sister, Megan Keller; his mother-in-law, Marie (the late John) Schlechty; his in-laws, Kevin (Terri) Schlechty, Cheryl (Darrell) Leeper; his nieces and nephews, Grant, his godson (Morgan) Keller, Evan Keller (Allyson), Zander Keller, Chad (Terra) Denniston, Alicia (Anthony) Cromes, Abby (Chad) Wilson, Brittanny (Doug) Breymaier, Adam Schlechty, and Kyndell (Brett) Kilgore, and numerous great nieces and nephews.

He graduated from Greenville High School in 1987 and devoted more than 43 years of his life to Keller Grain & Feed, Inc., where his deep passion for agriculture and the farming community was evident to all who knew him. He also worked alongside his wife, Tonya, operating their food trailer, The Purple Trailer, and took great pride in helping his son launch Classy Trashy LLC., cherishing the time they spent working together.

Christoph attended COF Greenville and faithfully served his community as a Darke County Fairboard Director, a member of the Pitsburg Lions Club, and a Greenville Elks member. Through each role, he generously gave his time and energy, forming lifelong friendships, and leaving a meaningful impact on the community he loved. Volunteering was close to his heart; you could often find Christoph showing up unannounced, ready to lend a helping hand wherever it was needed.

On March 1, 1997, he married the love of his life, Tonya, beginning a beautiful life together. For their honeymoon, he surprised her with their first cruise, igniting a love for cruising that stayed with him forever. As their family grew and they welcomed their beloved children, Christoph proudly embraced life as a devoted sports dad, horse dad, dog dad, and goat dad. He found his greatest joy cheering on his kids in everything they pursued.

Christoph will be remembered for his compassion, kind spirit, unwavering work ethic, and his truly selfless heart as a man of God. His smile and laughter were contagious, bringing warmth and comfort to everyone around him. Material possessions meant little to him; while he appreciated his gadgets and tools, what he treasured most was traveling and spending time with family and friends, sharing good food and meaningful conversation.

There will be a celebration of life for Christoph held on Saturday, January 10, 2026, starting at 5:00 PM at the Youth Building at the Darke County Fairgrounds, 800 Sweitzer Street, Greenville, Ohio 45331, with Pastor Alex Murphy officiating.
