Jefferson Symphony Orchestra


Dr. William Morse
Music Director & Conductor Emeritus

An announcement from JSO


Jefferson Symphony's music director and principal conductor, William Morse, has announced his retirement. He has worked for Jefferson County's largest classical music ensemble since 1998.


Morse will adopt emeritus status and retain artistic direction while the symphony’s directors search for — and then welcome — a new leader. Morse oversaw major expansion of JSO concerts through dynamic collaborations with guest artists, a summer concert series; then managed their cancellations due to the coronavirus crisis and oversaw the creation of JSO's virtual orchestra.


The symphony’s budget, ticket sales, and season subscriptions have risen steadily during Morse's tenure. He has also developed the widely admired Young Artists Competition and annual YAC Concert.

Maestro William Morse joined Jefferson Symphony as Music Director and Principal Conductor in1999. Dr. Morse holds bachelor and master degrees in music from Oberlin Conservatory and a doctorate in orchestral conducting from the University of Arizona. He has also studied at the Mozarteum Academy of Music in Salzburg, Austria. He is Professor Emeritus at Metropolitan State College in Denver where he conducted the Metropolitan State Symphony Orchestra and taught Advanced Conducting and Music Theory.

A man of diverse musical talents, Dr. Morse is fond of the literature for symphony and chamber orchestra. His dynamic conducting style, innovative musical taste, and outstanding musicianship have made him very popular with Colorado audiences.
