Timber Creek is eighteen years young and the newest high school in Keller ISD. The Timber Creek HS choir program has been active in the competitive arena of choir for the last six years and has grown to be a consistent presence in the online and competitive choral community. The chamber choir was founded in 2019, the year Adrian Kirtley started as the head director. Since then, the ensemble has had fifty-seven of its members make the all-state choir; they’ve been awarded first place at the 2019, 2021, and 2025 Madrigal Festivals; and first place at the 2022 and 2024 Festival di Voce competition. The choir performed at National ACDA in 2023 and Southwestern ACDA in 2024.
