Donald "Garth" Rettinghouse, 69, passed away on July 12, 2026. Born on January 29, 1957, in Pasco, Washington, Garth grew up in Pasco and Kennewick, where he developed a love for music, motorcycles, fishing, friendship, and serving others that would stay with him throughout his life.

As a young man, Garth played the trumpet and marched with the Columbians Drum Corps. At 18, he joined the Sacramento Freelancers, where he had the opportunity to compete at national championships. Those experiences gave him lifelong memories and reflected the enthusiasm and determination that would define him throughout his life.

Garth married Dee (Webber) Bell, and together they raised four children. Although their marriage ended, their love and friendship remained an important part of his life. Above all else, Garth was devoted to his family. Nothing made him prouder than being a father and grandfather. He treasured every opportunity to cheer on his children and grandchildren at their games, concerts, and activities, creating memories they will treasure for years to come. His greatest joy was simply being with the people he loved. He never missed an opportunity to tell his kids, "I love you."

Garth proudly served in the Army National Guard as a tank driver. His commitment to serving others continued long after his military service. He was a dedicated member of American Legion Post 34, where he served as chaplain. His willingness to lend a helping hand, offer encouragement, or simply spend time with someone in need left a lasting impression on everyone who knew him.

A true jack of all trades, Garth built a career with his hands and his determination. He worked as a carpenter, specialized in concrete work, drove trucks, and traveled throughout the country for construction projects, including work in Alaska following the Exxon Valdez oil spill. As a foreman for Colt Construction, he took great pride in helping build a nuclear silo.

Garth lived life with enthusiasm and never met a stranger. Whether he was riding his motorcycle, fishing, golfing, singing karaoke, watching sports, playing fantasy football with his sons, or spending time with friends, he found joy in life's simple pleasures. Those who knew him will remember his magnetic personality, warm smile, generous spirit, and the way he always saw the best in others. His favorite sayings, "God is good," "It is what it is," and "Livin' the dream," reflected the optimism and faith that shaped his life.

His faith in God guided every aspect of his life. Each morning began with time in his Bible, devotionals, and prayer. No matter where life took him or what he was doing, God remained at the center of it all. A faithful attendee of The Living Room Community Church, Garth lived out his faith by serving others with compassion, kindness, and love.

Garth is survived by his mother, Nita Rettinghouse; his daughter, Rheannon Joseph (Shawn); his sons, Brent Nunamaker, Brandon Rettinghouse, and Cody Rettinghouse (Jeannette); his beloved grandchildren, Jadyn Joseph, Cobren Joseph, Cassius Nunamaker, Leighton Nunamaker, Mason Rettinghouse, and Max Rettinghouse; his brother, Joel Rettinghouse; his former wife, Dee Bell; treasured friends Dave and Nikki Ricard; and his American Legion Riders.

He was preceded in death by his father, Don Rettinghouse, and brother, Andrew Johnson

Garth's life was a testament to faith, family, friendship, and service. He leaves behind a legacy of love, generosity, and unwavering compassion that will continue to inspire all who knew him. Though he will be deeply missed, the memories he created and the lives he touched will never be forgotten.
