Danniell entered the marching band/winter guard community in 2001 as a freshman at Arvada High School in Arvada, CO. After high school; he marched one season of The Cavaliers Drum & Bugle corps in 2004. In 2008 he re-entered the community as a teacher of several scholastic programs and an independent winter guard while performing with the Independent Open/World winter guard, Opus X(2009-10, & 2013). Danniell has been a member of the RMCGA board for several years and is currently training to become a new judge in the RMCGA winter guard circuit. 2022 marks Danniell’s twenty-first year since he joined this fantastic community, and he can’t wait to see every group back out on the floor after the craziness of the COVID pandemic!

Jeff Hargis has been involved with the color guard activity since 2006 as a performer, technician, choreographer, designer, director, clinician, and adjudicator. He began judging local winter guards in 2015 in the Equipment caption and has since expanded to include the Movement and General Effect captions. Jeff is passionate about teaching and mentoring young students and instructors and has had the pleasure of performing or being on staff with units in every classification in existence. He is especially passionate about helping students find opportunities to march drum corps and independent winter guard after completing high school. Jeff is currently pursuing his Master’s in School Counseling and hopes to become a high school counselor in the near future.
