Starting from an early discovery of John Coltrane, John was hooked on music quick.  It was Coltrane and other jazz artists that helped John choose trombone as an instrument.  While early studies and performances focused on classical music,  John quickly transitioned to study jazz with Jim McFalls and Dave Ballou at Towson University.  Towson's unique curriculum combined with his experiences in bands like 9 Mile Roots, Screaming Art Large Ensemble and Joe Keyes and Late Bloomer Band expanded John's view of music.  He also worked as a cruise ship musician.  


John was invited to join the first class of the graduate school of music at the Hartt School of Music - University of Hartford.  There John studied with renowned jazz trombone artist Steve Davis and Javon Jackson.  This narrowed his focus to learn the Jazz tradition, while he also taught himself to compose and to play trumpet and piano.  Currently John enjoys teaching trombone and trumpet, composing, studying, and performing as much as possible!
