Leslie G. Olenslager, beloved husband, father, grandfather, great-grandfather, and friend, returned to the arms of his Heavenly Father on Sunday, May 22, 2022. Les was born December 8, 1933, in Rupert, Idaho, to Alvin Olsen Olenslager and Veda Kate Nichols Olenslager.
Les was raised in both Rupert, Idaho, and Carson City, Nevada. Attending high school in Carson City, Les participated and excelled in many sports including football, basketball, and baseball, before graduating in 1952. During his high school years Les met the love of his life, Barbara Jean Baxter, and they were married July 11, 1953, and later sealed in the St. George LDS Temple.
Les studied electronics at Idaho State Technical College for three years before accepting a position in Las Vegas with EG&G, working at the Nevada Test Site. During these early years in Las Vegas, the family shared many weekends at Lake Mead. Les also enjoyed his free time on the golf course with co-workers and friends.
Continuing his career with EG&G, the family relocated to Los Alamos, New Mexico, during 1969 where they lived for three years. While in New Mexico, Les and Barbara’s new friends introduced them to square dancing; they fell in love with it, spending many weekends dancing the night away.
In 1972, Les took a break from EG&G to start a business venture with his brother in St. George, Utah. With the family being relocated, Les and Barbara reunited with lifelong friends and the family settled into the community. The family roots remained between St. George and Las Vegas for many years with Les eventually retiring from EG&G in Las Vegas, Nevada.
As an active member of The Church of Jesus Christ of Latter-day Saints, Les served in several church callings throughout his life. He especially enjoyed working with the youth and providing service to those in need.
Family was extremely important to Les and he supported his children and grand-children in all of their activities. In addition to his time spent boating on Lake Mead with his family and friends, Les had a great love for sports. Over the years, Les loved coaching and attending the many sporting endeavors of his kids, grandkids, and great-grandkids.
Les is survived by his three children, Marie Blazzard, Mark (Judy) Olenslager, and Debbie (Mark) Delahoussaye; eight grandchildren, Katy (David) Carter, Kimberly Ruesch, Kevin Blazzard, KC (Ashley) Blazzard, Brandon (Lauren) Olenslager, Brayden Olenslager, Kristin Delahoussaye, Dustin Delahoussaye; nine great-grandchildren and his half-sister Sherry Olenslager Clarke.
Les was preceded in death by his loving wife Barbara Baxter Olenslager, his three older brothers Alvin Olenslager Jr, Holt Olenslager, and Elwood Olenslager; great-grandson Bracken David Carter and half-sister Renee Olenslager.
