The Sanctuary organ was a gift to First Presbyterian Church from two longtime members, Mr. and Mrs. Robert C. Sharp. It was built by Austin Organs of Hartford, Connecticut, and installed in 1968. The organ features 6,642 pipes, most of which are located in chambers on either side of the choir loft, and in the rear gallery of the Sanctuary.

2014 Organ Renovation Project

A recent cleaning and renovation of the Sanctuary organ began in early 2014 and concluded in time for Easter Sunday, 2015. Built up dust and grime from recent construction required each pipe to be carefully removed for meticulous cleaning. The old analogue control system was completely stripped and replaced with a more reliable state of the art electronic control system. A whole new miniature control console was also constructed for the choir loft.
