The present organ is the second one to be installed in the church and was given in 1952 as a memorial by 290 members of the parish.  It was designed by Edgar Hilliar, long-time music director of St. Mark's, and is a signature instrument of G. Donald Harrison of Aeolian-Skinner.  It is a three manual, 66 rank instrument of five divisions (pedal, great, swell I, swell II, positiv, pedal) and with trompete enchamade. 

During 2002 and 2003, in celebration of its fiftieth year of continuous use, funds were raised to fully restore and digitize the organ.  The restoration was completed in the spring of 2004.  As a result of these efforts, our fine musical instrument has been returned to as-new condition.
