About Dave Marvin:

Dave's highly competitive programs have set many of the "percussion theatre" standards the activity now builds upon. Dave has been the Percussion Director at Northglenn High School for the past 30 years. Dave was the mastermind behind show concepts and visual coordination for the four time WGI World Champion the Blue Knights World Percussion Ensemble from 1999–2005.

Dave has served on the WGI board of directors and currently is the President of the Rocky Mountain Percussion Association. He served on the very first WGI Percussion Steering Committee through 2006 and has constantly been striving to develop a sound educational base for his and all indoor percussion students. Dave was instrumental in the creation of "Stampede", the first officially endorsed and sponsored drumline in the National Football League. To date, most of the teams in the NFL now have an official drumline as an additional entertainment source, thanks much to Dave’s innovative efforts.
