Cactus Harris

Director of Worship and the Arts

+ learn more

Hailing from Paso Robles, California, Cactus Sam Harris lives the cowboy life. He and his parents, Tom and Debby Harris, own Harris Stage Lines — a western entertainment ranch that hosts group parties and events, stagecoach and wagon rides, and clinics to teach people how to ride and drive horses, and to preserve the wild west. Taught by rodeo stars like Monty Montana and the Riata Ranch Cowboy Girls, Cactus relives the wild west by performing the western arts — trick-roping and whip-cracking. Aside from his wild-west background, Cactus is an accomplished musician entertaining audiences far and wide.

Harris’ musical talents began by taking saxophone lessons as a young boy in school. He taught himself both the accordion and the piano and then, during his sophomore year in high school, he touched an organ for the first time. Once again, he began teaching himself how to play, and he soon got a job playing for St. James’s Episcopal Church in Paso Robles, California, on their 1850’s William Stevens organ. Recently he installed a 1920’s Wurlitzer Theatre Pipe Organ on his family’s ranch in Paso Robles with the goal of holding concerts and events.

Harris holds a B.A in Music Education and M.A in Conducting from California State University Fresno, where he studied organ with Laurell Huber and Scott Horton, and conducting with Dr. Gary Gilroy. He has been a winner in the San Joaquin Valley Keyboard competition and been a guest organist at many different events. In 2012 he was a Biggs Fellowship recipient from the Organ Historical Society. Cactus has been featured with the Fresno State Wind Orchestra on the Disney Hall concert organ, and with the Yosemite Wind Orchestra at the Sydney Opera House and Sydney Town Hall organs. Cactus is an active member of the San Joaquin Valley American Guild of Organists, currently serving as Sub-Dean of the chapter. Harris has been the organist at UPC since fall of 2010.
