Kent Jue, Artistic and Executive Director

Kent Jue is thrilled and honored to lead Ragazzi’s artistic and administrative arms. During his tenure as Artistic and Executive Director, Kent guided Ragazzi’s growth plan as it became the largest boy’s chorus program in the Bay Area. He created two satellite programs for entry-level families, increased grant and foundation support, established Ragazzi’s first endowment, and achieved consecutive budget surpluses. Showcasing innovation and adaptability during the spring of 2020, Kent reimagined a program that kept Ragazzi boys safely singing. He pioneered new technology, maintained enrollment, and established Ragazzi’s health and safety plan. Under Kent’s leadership, overnight activities, including local, domestic and international touring, and camps resumed in 2022 after a three-year hiatus.
