Sheryl Stack has been teaching and performing in the Austin area since 1986. Stack is active throughout the area as a collaborative pianist, playing recitals, competitions, auditions, and concerts with instrumentalists and vocalists; bands, choirs, orchestras; and ballet and opera companies. She has appeared in concert and in shows with Conspirare, Chorus Austin, Austin Opera, Austin Symphonic Band, Inversion Ensemble, Austin Cantorum, St. Matthews Schola, Ballet Austin, The Georgetown Palace Theatre, Round Rock Symphony, Butler Opera Young Artists Program, UT Wind Ensemble, and UT Chamber Singers, among others, and has provided live accompaniment for Royal Academy of Dance annual ballet exams for a number of years, both in the Austin and Dallas areas. Over the past 30+ years, Sheryl has accompanied thousands of high school instrumentalists and singers at UIL Solo & Ensemble competitions, coaching them both musically and technically toward their best possible performances.

In 2023 Sheryl is celebrating 40 years of teaching music. An Adjunct Assistant Professor of Music at Austin Community College since January 2019, she enjoys sharing the joy of music theory, history, and literature with non-music majors in her Music Appreciation classes. She also maintains a private teaching studio of 25-30 students, teaching piano to students of every age and level, and teaching pianists how to play the organ.

Since 1988, Sheryl has served a number of Austin-area churches as organist and/or music director. She is currently with Westminster Presbyterian Church in central Austin, where she is pianist/organist, accompanies the adult choir, directs the children & youth music, and has started an intergenerational orchestra—a collective of instrumentalists for solos and small ensembles, all with the purpose of enhancing worship services through instrumental music and building relationships with each other in the process.

Sheryl received her BM degree at Wichita State University (1985) and MM at The University of Texas in Austin (1988), both in Piano Performance, and later a second MM in Collaborative Piano (2011) at the Butler School of Music, UT Austin, as well, where she was a Teaching Assistant for a total of six years and was a member of the inaugural class of the collaborative piano program.
