To upgrade an Allen organ installed in the 1970s, Blessed Trinity selected an Allen 58 Stop, three-manual digital and pipe combination organ with nine stops of pipes. The console has a custom oak finish, with matching custom oak casework for the pipes. The Principal pipes are on the Great (add or substitute), and the Flute pipes are on the Swell (add or substitute). All speakers and interface equipment are located behind the pipes. The organ is comprised of two sections: Great-Pedal-Choir on one side, with the Swell on the opposite wall. The gold-finished pipe work was supplied by Jim Lauch.
The older 1970s Allen was then reinstalled in the church's chapel with new speakers.
Organist Dick Saalfeld "did the shopping" and made the recommendations to Father Pat Sheedy and to the committee. Shortly after its installation, the new Allen was the centerpiece of an Organ Workshop the day before its official Dedication.
