Michael Kemp
Founder and Artistic Director Emeritus

Michael is a member of the legendary Kemp family of choral musicians. Educated at Oklahoma University, Westminster Choir College, and the Royal Conservatory of Music in The Hague, Holland, Michael was educated equally in the areas of voice performance, viola performance, and conducting. In addition to institutional education, he also studied privately with renowned choral authorities Paul Salamunovich, Philip Brunelle, and Alice Parker, with extensive summer study with Robert Shaw.

Prior to fourteen years of teaching Upper School music at Germantown Academy, PA, Michael served as Director of Music Ministries of Abington Presbyterian Church in Abington, PA, after holding other significant church music positions in Nashville, TN and Arlington, TX. While in Texas, he also founded and conducted for eleven seasons the Arlington Choral Society, which critics placed “on the top rung of choral music in the Dallas Metroplex.” During that time he was a choral and church music lecturer at SMU’s Perkins School of Theology.

Recognized for his exceptional ability to build programs, Michael has founded and built from ground level many successful ensembles, including four church youth choirs and two high school choirs, two adult community choruses, and one adult community symphony orchestra, in addition to expanding and enhancing existing ensembles. Michael has twice trained choral conductors from throughout Jamaica, and his choirs have toured internationally to Salzburg, Vienna, and Krakow.

In May 2019, Michael retired from conducting the two adult ensembles that he founded, the Academy Chorale and Orchestra (now known as the Montgomery County Chorale and Orchestra). He is now music director at Trinity Presbyterian Church in Berwyn, PA.
