The 22 rank instrument built by the Reuter Organ Company of Lawrence, Kansas was originally installed in 1955. The instrument was intended by Reuter to be a prototype and model for its flagship, landmark instrument designed for Whatley Chapel at the former Colorado Women’s’ College, which was installed in phases during the early 1960s. The Great division of the PHCC organ was completed in 1964 with an addition of 6 ranks; the swell division was completed in 1969 with the addition of 4 ranks; while the pedal division was completed in 1985 with the addition of the 16 foot reed.
