Calvin has been an instrumental part of various teams delivering many mega events like the Super Bowl, Las Vegas Grand Prix, NCAA Final Four, and College Football Championship, but he hopes to one day work at the FIFA World Cup or the Olympics. Stratoscope clients rely on Calvin’s vast experience managing challenges before they become incidents to ensure positive outcomes. From corporate events to festivals to arenas and mega events Calvin has a wealth of experience.
His most notable success story is when he was asked to serve as acting VP of Security at the Chase Center, home of the Golden State Warriors, where he developed their security and venue operations from scratch. As a testament to his leadership, when the arena flooded on Thanksgiving Day in 2019, he led the team in a massive clean-up mission and, in under twelve hours, removed all the water so the game could go on. Most recently, Calvin led one of Stratoscope’s largest projects to date, the inaugural Formula 1 Las Vegas Grand Prix, a 3.8 mile temporary street circuit weaving through the neon heart of The Strip.
Calvin’s best advice to clients is that there is always room for improvement in any operation or organization. “Experiences are the one thing that people remember when they attend an event, go to a venue, or interact with an organization. Experienced professionals create amazing guest experiences.” Calvin resides in Henderson, NV with his girlfriend and their dogs.
