About Us

Plenum Organ Company is owned and operated by John Roper. John works as an organ technician, consultant, historian, and musician for several churches, museums, and organizations across New England. A member of the American Institute of Organ Builders, Organ Historical Society, American Guild of Organists, and American Choral Directors Association, John has worked on the largest pipe organ in the world (Atlantic City Boardwalk Hall) and some of the smallest. His past employment includes Spencer Organ Company and Ortloff Organ Company, and he continues to work on projects for a number of builders in the area.

Plenum Organ Company specializes in instruments that have been historically neglected, and we are experienced in finding them the attention and funding they require to be resurrected and rediscovered. We are happy to help with any historical research, documentation, and photography required to increase knowledge about a pipe organ. We are fully insured for all work undertaken.

As firm believers in sharing knowledge and increasing our own, we welcome collaborations with colleagues in the pipe organ and adjacent industries. In our quest for excellence and innovation, we recognize the value of collective wisdom and actively seek guidance from experts whenever we encounter new challenges or specialized topics. This collaborative approach ensures that we continually enhance our expertise while contributing meaningfully to the broader pipe organ community.
