Tom has an unusual, and colorful, history in the Marketing and Communication field. During his seventeen years living in Los Angeles and working in the entertainment industry he co-produced the “The Imperial Bells of China”, the largest group of Chinese artists that ever toured the US, twice. He also worked closely with Tai, the amazing Indian elephant that starred in the movie, “Water for Elephants,” when he founded The LA Circus, an award-winning one-ring community circus sponsored by the City of Los Angeles. Tom also worked on several of the largest Music Festivals of the 90s, including the Amnesty Int’l World Tour w/ Peter Gabriel, Sting and Bruce Springsteen, Fiesta Broadway, and the US Festival. As Tom says, “After running a circus for two years, there’s not much that can surprise me. If you can deal with a dozen clowns on a daily basis, everything else is a piece of cake.” Thirteen years ago, when Tom moved to Prescott, he started the Folk Sessions Radio Show, still broadcasting on the KJAZZ Radio Network. He received a Bucky Award for Media in 2013, performs at church halls and folk fests with his wife, Christa, and is proud to be a “Man Who Cooks”.
