Rob has been a professional trumpet player in the Philadelphia area for the past 25 years. His career started with studying with the late Don McComas of the Philadelphia Orchestra, which led him to many opportunities playing classical music in many different settings in the Philadelphia and tri-state area.
Currently Rob is a freelance trumpet player in the Philadelphia area, and is a senior faculty member at Community Music School in Collegeville, PA
In 1992, after graduating high school, Rob met friend and colleague Kevin Rosenberry. Kevin formed Mirandola Fanfare Trumpets - a trumpet ensemble which played for Renaissance Fairs - and corporate events all over the east coast. Upon Kevin’s untimely passing in 2007, Rob has kept the tradition of Mirandola Fanfare Trumpets alive and well as Kevin would have wanted. Kevin is, and will remain, to be missed dearly.
Around 1999, Rob became interested in jazz and commercial music which opened the door for a whole new career for the trumpet player. Around this time, Rob began playing in funk bands, big bands, salsa groups, polka bands, and playing for musical theater productions.
In 2003 Rob formed the jazz group Anomaly and recorded his first jazz project entitled, “Trumpet and Batteries not included”. In 2005 he went on tour with the North American Tour of the Broadway Musical ”42nd Street” and recorded another CD with his band Anomaly entitled, “Some Assembly Required” that received national reviews.
In 2006 Diener decided it was time to pursue the serious study of Jazz and Improvisational music. At this point he studied with world renowned jazz educator and performer, Jimmy Amadie, for 6 years in Philadelphia. This led to the formation of yet another group. The Jazz 5 Pack was formed by Rob and fellow Amadie student, John Loos.

I would like to dedicate this website to my mother, Jane, my father, the late Arthur W. Diener, and my sister, Joan, for all their support. I would especially like to thank my wife Tina for taking many of the videos and photos over the past 18 years, and for her unyielding support of my artistic endeavors!
