Dr. Michael Jacko

Music Conservatory / Orchestra / Music Theory

Michael Jacko grew up in the Metroplex and returned to Dallas in 2015 from the Washington, DC area. Since then, he has served as Head of Orchestral Studies at Booker T., and he has led the Music Conservatory since 2019. He has treasured each day, week, month, and year at Booker T. because of the astonishing growth that this school inspires in both its students and faculty.

Immediately prior to teaching at Booker T., while living in the nation's capital, Dr. Jacko served as Music Director of the Maryland Sinfonietta and the University of Maryland Repertoire Orchestra; as well as staff conductor for the Capital City Symphony, the University of Maryland Symphony Orchestra, and the Youth Orchestras of Prince William. In Washington, Jacko also worked in the Music Department at the National Gallery of Art, where he served as Cover Conductor for the National Gallery of Art Orchestra. He conducted the Maryland Sinfonietta in the opening program of the National Gallery's 65th American Music Festival, which featured a selection of works by Cage, Copland, and Ives that the Washington Post called "fascinating," "illuminating," and "a rich study in American mythmaking." A devotee of American symphonic music, Jacko completed his doctoral thesis at the University of Maryland, in which he discussed the new editions of Charles Ives's Fourth Symphony.

Jacko began his conducting study while pursuing a degree from the Faculty of Languages and Linguistics at Georgetown University. While at Georgetown, he conducted the University Wind Ensemble and Symphony Orchestra. Jacko completed further studies at Bard College, the University of Denver, and the University of Maryland, where he served as Assistant Conductor to various instrumental, choral, and operatic ensembles. While at Bard, he coordinated and conducted a string ensemble for Noemie LaFrance’s site-­‐specific ballet, Rapture, staged atop the magnificent Frank Gehry-­‐designed Richard B. Fisher Center, and he also led the Woodstock Chamber Orchestra as a guest conductor.
