Meet The Team Behind 567Sing
Curt Hansen
Owner / Vocal Coach
Curt Hansen is a Broadway performer whose career spans major productions, national tours, and nearly a decade of leading roles on some of the industry’s biggest stages.
A Wisconsin native who learned to dance and sing through community theatre, Curt’s early determination carried him into shows like Hairspray, where he once learned full Broadway choreography in just 3–4 days, and Next to Normal, Kinky Boots, and Wicked. His eight‑year journey as Fiyero (across three different companies) became a defining chapter, a role he describes as “so in my body and so a part of me” after years of returning to it stronger each time. Known for his physicality, coachability, and ability to grow inside demanding roles, Curt built a reputation as a performer who could anchor a show with both confidence and heart. After retiring from performing, he shifted his focus to teaching, driven by the belief that “reflecting back on it is really inspiring to help people get there.”
With that experience, Curt founded 567Sing to help dancers develop reliable vocal technique and prepare for the professional opportunities he knows firsthand.
