Ramsey's interest in the creation of worlds began when he was a University of Wyoming astronomy major. He learned that there were several worlds he could create here, on this one, and that he could travel anyplace on stage and in movies while working as an actor in the theatre at night and organising differential equations by day. He has worked on a wide range of those worlds throughout the many years that have passed. His first project was to art-direct Roseanne, a tiny town in the Midwest. More recently, he created and animated the Second Age settings for The Lord of the Rings. Since then, he has contributed to Marvel's bold visual direction as the PD of Captain America: Brave New World, developed an eerie gaming firm for Matt Shakman's The Consultant, and built the snug nest that Kaitlyn Dever must protect from invaders in No One Will Save You Now. He has worked as an art director on projects that span time and space, including Team America, Star Trek: Into Darkness, Mirror, Mirror, Tomorrowland, and Guardians of the Galaxy, Vol. 2. He has also contributed to the future worlds of Minority Report and A.I. Ramsey is a production designer who worked on the films Peppermint, Hotel Artemis, 10 Cloverfield Lane, and the Sundance Choices Waitress and Right At Your Door. He has also created national ads for brands including Budweiser, Microsoft, Capri Sun, and Dodge for the Super Bowl. Because of his work on the live-action trailer for The Bee Movie, he received a nomination for an Art Department Guild Award. Ramsey recently created the Webslingers multimedia interactive attraction as well as the Avenger's Campus for Disney's California Adventure. His earlier design, the Animation Pavilion at DCA, was recognised with a THEA award, which is the Oscar of themed entertainment. His contributions to several global attractions and events include the first winterlit cityscape in Santa Monica, the Don Quixote attraction in Japan, and the Royal Saudi Wedding in Riyadh. He has continued to be involved in theatre throughout the years, having designed national tours of Martina McBride's Christmas in addition to award-winning regional theatre sets from California to New York.
