Welcome to the Summer School of Liturgical Music at Holy Trinity Seminary (SSLM)! We have been educating Orthodox choir conductors, singers and readers since 1992.  The intense two-week program takes place each summer in Jordanville, New York, on the territory of Holy Trinity Monastery of the Russian Orthodox Church Outside of Russia.  SSLM is accredited by the Board of Regents of the State University of New York.
