Glenn, a native of Berwick, PA,
began his music training at age nine. After high school,
he attended the Curtis Institute of Music in
Philadelphia, then joined the Marine Band in Washington,
DC as trombone soloist. In 1956, he started a nine year
stay with the New Orleans Symphony, which presented the
opportunity to play jazz with Al Hirt and Pete Fountain.
During that time, he also spent six seasons with the
Santa Fe Opera Orchestra. He joined the Chicago Symphony
in 1965, and while there, was also active in commercial
studio work. In 1968, Glenn moved to the Philadelphia
Orchestra as principal trombonist. In addition to
teaching private students, Glenn served as Instructor of
Trombone and Brass Ensemble at the Curtis Institute.
Glenn retired from the Philadelphia Orchestra in 1995
and from the Curtis Institute of Music in 1998, but he
continues to coach and play in many jazz groups
including his own Raz-Jaz Dixie Band.
