Terry Byrne will retire at the end of the week of November 2, 2026, after thirty-six years as General Manager of the Westside Theatre. Dalton Zogleman, who has overseen operations at the Off-Broadway venue since 2018, will succeed her.

Why it matters

The transition places leadership of the Westside Theatre, an Off-Broadway house in New York City, in the hands of a successor who worked alongside Byrne for eight years. Zogleman is only the second General Manager in the theatre's history.

Byrne guided the Westside Theatre through more than sixty productions across thirty-six years as General Manager, including the twelve-year run of I Love You, You're Perfect, Now Change. Little Shop of Horrors became the longest-running production of the musical in history at the venue in September 2025, and the source does not detail any change to that run under new leadership.
