After spending time advocating for public education funding, he taught in both Aurora Public Schools and Denver Public Schools.

He enjoys strumming chords on the guitar and taking a nightly walk with his children around their neighborhood. If you see him dashing in or out of the building, it’s because he is in year three of earning his doctorate in English and Literary Arts from the University of Denver.  Students can find his website here, which (in non-pandemic years) is where he lists all his readings and homework.

Leo Bond
Humanities, Drama

Leo earned a BA in Theater (Acting/Directing) from DeSales University, an MA in Higher Education (Spirituality, Faith, and Formation) from Boston College, and an MA in Theater (Directing) from Villanova University. Leo fell in love with theater at the ripe old age of eleven after seeing a professional production of The Sound of Music. Although the works of William Shakespeare remain his deepest love, Leo secretly still adores musicals. Leo moved to Denver in 2019, but made his first appearance in Colorado back in 2013 when he served as the assistant director for a production of A Midsummer Night’s Dream at the Colorado Shakespeare Festival. Other career highlights include performing for three seasons at the Pennsylvania Shakespeare Festival, producing a new work world premiere at the Philadelphia Fringe Festival, and directing a solo performance production for the world’s largest solo theater festival, United Solo. If Leo is not in rehearsal, which is rare, he can most likely be found cuddled up under a cozy blanket on a comfy couch with a warm cup of tea and a good long book. Leo credits his eight siblings for his deep love of communal creative play and is absolutely delighted to share his passion for active embodied theater here at DWS.
