Leon Grant Cuthbert

Leon Grant Cuthbert passed away peacefully at his home on April 22, 2026, at the age of 94. He was born on August 11, 1931, in Bingham Canyon, Utah, and lived a full and meaningful life devoted to family, faith, and community.

Leon was known for his signature dry sense of humor. He delighted in sharing stories from his childhood in a mining town and the many adventures of his long life. His storytelling was rich with wit, and his punchlines often landed with memorable impact.

A lifelong learner, Leon pursued his passion for education with dedication. He earned a Bachelor of Science in Psychology from the University of Utah, a Master of Science in Health Science from California State University, Northridge, and a Doctor of Public Administration from the University of La Verne. He was a registered Professional Engineer in Safety Engineering, held a California teaching credential, and was also a credentialed minister with the Universal Life Church—one of his more lighthearted and quirky accomplishments.

While attending the University of Utah, Leon met the love of his life, Monica Youngberg. They were married on July 1, 1954, in the Salt Lake Temple of The Church of Jesus Christ of Latter-day Saints. Soon after graduating, they moved to Southern California, where they built a loving home—primarily in the Los Angeles area, with a few years in San Diego. Over the course of 17 years, they welcomed six children into their family.

Leon began his professional career in aerospace as a Safety Engineer in 1955. In 1972, he accepted a position with San Diego Gas & Electric, relocating his family from Northridge to San Diego. His commitment to education led him to join the faculty at California State University, Northridge, where he taught practical industrial courses and inspired many students—all while continuing his work in the aerospace industry.

Leon cherished time spent with his family and especially loved the outdoors. He supported the wide-ranging interests of his children and was a constant presence at beach outings, home projects, school sports, and band activities. He was Band Parents’ President three times. Family camping trips were a particular joy. One memorable adventure at the Grand Canyon involved a torrential rainstorm and Leon’s firm instruction not to touch the tent walls—advice that went unheeded, resulting in water pouring in and a thoroughly soggy night. In later years, he upgraded to traveling in the family’s beloved camper, “Campy,” exploring the historic Native American lands of the American Southwest. These experiences, along with countless others, created treasured family memories.

Later in life, Leon and Monica expanded their love of travel, exploring both the United States and destinations abroad. A meaningful trip to Northern Ireland allowed them to visit places connected to Monica’s father and their son Mark’s missionary service. Another highlight was traveling to West and East Germany before the fall of the Berlin Wall, following their son Jeff’s mission there.

After retiring from a distinguished 45-year engineering career, Leon embraced a new and unexpected chapter. He brought his vibrant personality to the screen as a film and television extra, appearing in more than 125 productions, including Catch Me If You Can, Bruce Almighty, Win a Date with Tad Hamilton!, The Bernie Mac Show, and The West Wing. His enthusiasm for performing even reached international audiences—in El Salvador, he was affectionately known as the “YMCA Dancing Grandpa.”

Leon will be remembered for his intelligence, warmth, humor, and unwavering devotion to those he loved. He also had a deep compassion for animals, forming special connections with the many dogs and cats who were part of his life over the years.

He was preceded in death by his parents, his four siblings, and his beloved daughter, Debbie. He is survived by his devoted wife of nearly 72 years, Monica, and their children: Mark (Georganne), Stephanie (Edward), Jeff (Chris), Vicki (Todd), and Michael. He also leaves behind 22 grandchildren and 32 great-grandchildren, all of whom carry forward his legacy of love, curiosity, and joy.

Leon’s life was rich with purpose, adventure, and connection. He will be deeply missed by all who knew and loved him.

In lieu of flowers the family encourages you to remember Leon by contributing to a charity for which you have a special affinity.
