About Denver DrumZ & Music

Our Story


Denver DrumZ began back in late 90's, when JB Maroncelli, a local musician, elementary school band teacher, and single father of two children decided to open his own private lesson studio. Since that time JB has built Denver DrumZ up from teaching a handful of students in his living room, to teaching more than 20 students a week in his small music studio in Denver, CO. 

In 2019, JB expanded Denver DrumZ from a small music studio into a full on musician's paradise. JB was joined by fellow musicians and music teachers Mark McKenna and Andy Metzger to build a space that provides music lessons, instrument sales, practice studios, and a venue for every kind of event or performance, under their new name: Denver DrumZ & Music
