Celaya has appeared on Broadway and worked with Sony Records and other various TV commercials. In March 2006, the Today Show featured a segment on the auditioning process for Broadway shows in New York. The segment followed BYU alum Jason Celaya who was auditioning for a very popular and long-running off-Broadway show called Altar Boyz. The cameras caught moments of Jason auditioning and being offered the lead role in Altar Boyz on national television.
In 2010, he hosted the "Give Me a Chance I'll Show You My Dance" contest in Highland, Utah.
