The organ in the sanctuary is a Moller Opus 11828 with 9 ranks and 2 manuals. The organ was installed in 1991. The company that made the Moller is now out of business. The church has the organ pipes tuned once a year.
This organ is unique in that the engineers who made the organ worked directly with the architects who designed the building to make sure the sound was perfect. That is the reason the sanctuary has hard floors (instead of carpet) and hard walls.
