The founders of CLEF have been involved as both musicians and liturgists in ensembles for over half a century. Our team includes university-trained musicians, doctorate-level liturgists, as well as those with no formal training. We have been involved in ensembles with ongoing, continuing formation, as well as those who are left on their own to find competent training. We realize a considerable void exists in the formation and training afforded to ensembles. Given the wealth of experience and training we as a group possess, we feel called to share our gifts with others.

Dr. Ken Gilman, PhD

Ken recently retired from his 16 years as music director at St. Michael & All Angels in Albuquerque. He returned to the back row as an obbligatist on a variety of instruments – mandolin, bouzouki, violin, octave viola, bass mandolin, etc. The banjo has even snuck in a time or two. He loves thinking through what diverse musical elements do to enhance the melodic, harmonic, and rhythmic elements in the ensemble, as well as ensemble as a community. With roots in the music of the Celtic Diaspora, he has played in bands in New England and Europe as well as the Southwest. As a semi-retired psychologist and mediator, he works with first responders, especially around teamwork, communication, and burnout.

He is currently enjoying retirement after a varied career, including stints as an Executive Chef, Owner-Operator of a highly successful computer operations company, and sixteen years with the National Association of Pastoral Musicians. Peter began his career fifty-three years ago as an ensemble musician in 1969 when Sister Maureen, who knew he played guitar, asked him to help form the first “folk group” in the parish. Aside from a few breaks for life and jobs along the way, he has been an ensemble musician since.

Steve lives in Washington, Michigan, with his wife, Ruth.

Chris St. Clair

Chris got his start as a pastoral musician in the late 1970’s while still in high school and hopes that his old parish eventually forgives him for those early years. (This was many years before he met any of our esteemed faculty). He is a retired embedded software engineer who specialized in Real-Time, Embedded software for testing such things as communication satellites and The US Laboratory Module of the International Space Station. He has written flight software for one human-rated spacecraft and done a whole lot of ‘odd job’ software assignments for his former employer. He describes himself as a pastoral musician trapped in an engineer’s body. He and his wife Laura (aka ‘Charlie’) live in Jefferson City, MO., with their dog Astrid.

  • Our Technical Infrastructure Committee oversees all things related to tech and data that make our programming, both online and in person, possible. Committee members include Chris St. Clair (chair, board liaison) and Matthew Wesley.
  • Our Communications Committee helps shape our message and reach ensemble musicians via the website, social media, and other channels. Committee members include Peter Maher (board liaison), Linda Wesley (chair), Laura St. Clair, Tracey Boulware, and Ray Mullins.
