Michael Diorio

As an organist and choral conductor Michael Diorio has performed throughout the United States, the United Kingdom, Germany, France, the Czech Republic, Italy and Austria, where he was presented with a citation by the Mayor of Innsbruck for an outstanding public performance at the Jesuiten Kirche. 

A New Jersey native, Dr. Diorio received his Bachelor of Music in organ performance from Westminster Choir College, studying under Professor Eugene Roan. He earned his Master of Music and Diploma in organ from the School of Music and Institute of Sacred Music at Yale University, where he studied with Dr. Martin Jean. At Boston University, where he was a pupil of organist James David Christie, he received the Doctor of Musical Arts in organ performance, summa cum laude. He has studied organ improvisation with David Hurd, Bill Porter, and Stefan Engels. 

Dr. Diorio’s musicological studies led to his creation of a first edition of the Messa Hyemalis in A by Mannheim School composer Franz Xaver Richter (1709-1789), which is published by the German firm Carus-Verlag of Stuttgart. The edition received its American premiere at St. Thomas Church, Fifth Avenue, by John Scott and the St. Thomas Choir of Men & Boys, and its European premiere at the Strasbourg Cathedral in France. His choral compositions may be found at Paraclete Press, Church Music Publishing, and GIA publications.

Presently, Dr. Diorio is in his 13th season as Organist & Director of Music at Church of the Redeemer, Bryn Mawr, where he oversees a comprehensive choral and music program. He has served Adjunct Assistant Professor of Organ at Westminster Choir College in Princeton and has served on the faculties of both The Shipley School in Bryn Mawr and The Lawrenceville School.
