Steve Casey is the oldest of three children born to Peggy and Walt Casey. Born in Portland, Oregon, Steve arrived in Las Vegas in 1951 as a three-year-old via Glendora, California. His childhood memories are of small-town Las Vegas. He grew up near Tropicana Avenue and Eastern Avenue in a house his parents built by hand. The Casey family lived beyond municipal roads, so Steve worked his newspaper route by horse and occasionally rode his horse to Paradise Elementary School. In 1970 Steve graduated from the University of Arizona with a degree in Business Administration. Like his father, Steve is an entrepreneur. After starting his own company supplying commercial carpets and dust mops he joined his father’s business, Walt Casey Water Conditioning (later Walt Casey's Culligan), and took over the company when Walt retired. Steve sold the company in 2000 and in his retirement has become an accomplished photographer.
Steve and Linda Schneider married in 1975 in Linda’s home town of Flossmoor, Illinois. After their marriage they moved to a house Steve owned near the Palace Station, on El Mirador Street in the Ward 1 section of Las Vegas.
Besides contributing to Las Vegas through his work, Steve has a long history of philanthropy. Steve joined Las Vegas Rotary Club in 1974 and became president in 2004.
