Gregory Prechel received his composition and orchestration training at California State University Long Beach, and also studied privately with Hollywood composer/orchestrator Albert Harris and award-winning TV/film composer Alf Clausen.  He began his musical career as a trumpeter, going on to become a freelance composer, arranger, and orchestrator in the Los Angeles area.

He has composed, conducted, arranged, and/or orchestrated for several television shows including "The Simpsons," "NBA All Star Game," "Futurama," "King Of The Hill," and "American Idol."  Gregory is currently composer and music director for a new children's series, "Mack & Moxy," that is premiering on PBS this fall (2016).

His compositions, arrangements, and orchestrations have appeared in many feature films including Disney's "Air Bud" and "Air Buddies" franchises, Miramax's "Scary Movie" franchise, "Chestnut: Hero of Central Park," Disney's "Lion king 1.5," and "Mickey’s Philharmagic." He has composed unique original score for documentaries, including the film "Monganga" (set in the Congo), using authentic African instruments with symphonic orchestra.

Mr. Prechel has also composed, arranged and/or orchestrated many years for Walt Disney Company Theme Parks, working on numerous films, DVD's, shows, and parades, including arrangements for Christina Aguilera and LeAnn Rimes. 

He also has been commissioned to compose, arrange, and/or orchestrate over one hundred orchestral works for symphony orchestra.  These works are being performed regularly by major symphonies throughout the United States and internationally, including the Hollywood Bowl Orchestra, Cincinnati Pops, Houston Symphony, Pacific Symphony, Long Beach Symphony, Atlanta Symphony, Buffalo Philharmonic, and many others.  

Premiering early in 2009, The Youngstown Symphony Orchestra, under the music direction of Randall Craig Fleischer, commissioned Mr. Prechel to compose a "classical series" original twenty-five minute multi-movement work entitled “Impressions at the Butler Institute of American Art," inspired by the permanent collection at the Butler Institute in Youngstown, Ohio.  In 2010, Gregory was again commissioned to compose a twenty-five minute multi-movement work, this time for the Anchorage SymphonyOrchestra.
