Twentieth-century visitors to the Las Vegas Sands Hotel experienced the masonry work of Anthony A. Marnell, who removed his family from Riverside, California, to North Las Vegas in 1952 in order to build that structure. When he formed his own masonry company in 1958, he taught his namesake nine-year-old son the skills of a mason and the value of honest work. The younger Marnell learned all he could about construction from his father and completed his education by graduating USC School of Architecture in 1972, serving his apprenticeship, and becoming licensed in 1973. After designing McCarran Airport's A and B Gates, he teamed up with Lud Corrao in 1974 to form Marnell Corrao Associates, the first design-build firm in Southern Nevada. Marnell Corrao built many of Southern Nevada's most iconic hotel-casinos including the California Hotel, Maxim Hotel, and Sam's Town and Steve Wynn and Treasure Island, The Mirage, Bellagio, and New York New York as well as the Rio All-Suite Hotel and Casino and the M Resort Spa Casino. In this interview, the Riverside native speaks to the importance of teaching future generations about the value of work, of earning the sense of accomplishment, and of fueling one's inner spirit. His philosophy built a work environment that encouraged employee longevity from the beginning in 1974 (he is employee number one, and his assistant is employee number two). He talks of the American Institute of Architects (AIA), of entrepreneurial gamesmanship, and of casino greats Bill Boyd, Jay Sarno, Cliff Perlman, Kirk Kerkorian, and Steve Wynn. He describes the evolution of Las Vegas resorts from prioritizing casino games to fine dining to night clubs and entertainment. He credits his own Rio staff tradition of serving Chef's Table to the employees and the Rio's award-winning chef, Jean-Louis Palladin, for beginning the Las Vegas food renaissance in the late 1990s that rebranded Las Vegas as a Mecca for celebrity chefs. The nine-year-old who worked part time in his father's masonry business learned his lessons well, much to the benefit of Southern Nevada's growing skyline, its residents' growing waistlines, and its businesses' growing bottom lines.
