About Siskiyou Singers

Mr. Mark Reppert studied conducting, composition, piano, and music history at the University of Southern California, graduating with a degree in Music History. He received a master’s degree in Piano Performance from California State University, Chico, graduating with distinction.

Mr. Reppert began his teaching career in California in 1975, teaching every level from kindergarten to adult — band, orchestra, elementary music, college music appreciation, community choir, middle school and high school choir. Moving to Oregon in 1998, he became director of choral music at North Medford High School, where his award-winning choirs were a fixture of the musical community.

During his tenure, the choir has performed major works including the Chichester Psalms of Bernstein, the Mass in D of Dvořák, and the Coronation Mass of Mozart — alongside many world premieres of works by local composers.

Mr. Reppert retired from teaching in 2008 and is now an active musician in the Rogue Valley. He has served as music director at Camelot Theatre (Sweeney Todd, Cabaret, Gypsy, Les Misérables) and as an accompanist throughout the valley. His compositions and arrangements have been performed by many groups throughout Oregon and California, and he is a choral adjudicator for both middle school and high school competitions.

In 2003, Dr. Petrucelli moved to the United States and received a Master’s of Music from Baylor University and a Doctor of Musical Arts in Piano Performance from the University of Nebraska, Lincoln. She has also studied Historical Performance Practice on fortepiano.

Dr. Petrucelli is an accompanist not only for Siskiyou Singers, but also for the Rogue Valley Chorale and the Rogue Valley Peace Choir. She serves as a musician at Ascension Lutheran Church in Medford and is a collaborative pianist at Southern Oregon University’s Music Department.
