He and his young family moved to Wright, WY, in 1982, where he began a 40-year career in the mineral extraction industry of Campbell County. He started at Black Thunder Mine as a diesel mechanic and through the years, became a maintenance manager at various properties. Their union was a testament to enduring love, as they supported each other through life's joys and challenges. Together, they raised three remarkable daughters, Stacy Apodaca, Nicky Flores, and Trisha Kleiboeker, who became some of his proudest accomplishments. His love extended further with five grandchildren: Tallie, Keegan, Jeremy, Eli, and John; and four great-grandchildren: Greenlei, Locklyn, Brixton, and Silvertin. They filled his life with joy and laughter. Steve embraced life fully, finding pleasure in restoring his dad’s 68 GMC classic truck and embracing the great outdoors. His love for camping in the stunning Big Horn Mountains and the Black Hills of South Dakota allowed him to connect deeply with nature, creating beautiful memories that will live on in the hearts of his family. He fostered connections that would last a lifetime, and his loyal spirit touched many lives. He is survived by his loving wife, Cynthia; his daughters, Stacy (Phil) Apodaca, Nicky (Arnie) Flores, and Trisha (Joe) Kleiboeker and his treasured grandchildren and great-grandchildren, who will carry forward his legacy of love and family.
