Career
Trevor Dietz built a remarkable career in the music industry through hard work, dedication, and a deep understanding of live music culture. Before becoming known internationally through his association with Fontaines D.C., he had already spent many years promoting concerts and supporting artists in Dublin.
One of the most significant chapters of his career was his involvement with The Workman’s Club, one of Dublin’s best-known live music venues. He began working with the venue around 2010 and quickly became an important figure within its operations. Through his role, he helped create opportunities for emerging musicians and introduced audiences to new talent.

According to Dietz, he initially booked the band to perform at The Workman’s Club several times. Impressed by their talent, ambition, and originality, he decided to take the relationship further. What started as a promoter-artist connection eventually evolved into a management partnership.
Dietz officially began managing Fontaines D.C. in 2016. At the time, the band was still developing its identity and building a following. However, he immediately recognized their potential to become a major international act.
