He currently serves as music director for the Tucson Masterworks Chorale and Christ Presbyterian Church and works in the Catalina Foothills School District. He also performs as a pianist and vocalist at Tucson’s Gaslight Theatre and as a Music Director at Arts Express Theatre.

His current project, Breathing in the Awe, is a choral album inspired by U.S. national parks, which the Tucson Masterworks Chorale will premiere in Spring 2026. The project reflects a fascination with nature and Luke’s desire to celebrate the beauty and wonder of these parks through music.
