Glarum enriched Lewis & Clarkâs choir program in many ways, including bringing multiple well-known composers and musicians to do workshops and perform with the choir. Some of the more notable guests include composer Darius Milhaud, professional koto player Kimio Eto, and composer and conductor Alan Hovhaness.

President John Howard presents a certificate designating the Lewis & Clark College Choir as the Official Broadcasting Choir for the United Presbyterian Church to L. Stanley Glarum and John Groller
In 1962, the Lewis & Clark Choir received an incredible honor: it was named the 1962 official radio and television broadcasting choir for the United Presbyterian Church in the U.S.A. Recordings of the choir were used for ten broadcasts of the 1962 Protestant Hour and they gave three large concerts, in San Francisco, Los Angeles, and at the 1962 general assembly of the church in Denver. Before going to Denver, the choir also held a benefit concert in Portland to help cover travel costs.
In addition to his work as choral director at Lewis & Clark, Glarum worked at various summer programs through and apart from Lewis & Clark. These programs, some for high school students and others for college credit, provided students with opportunities to study music intensively for a few weeks at a time, learning the nuances of choral singing and musical collaboration. In particular, Glarum also founded the Haystack Choral Conductors Workshop which is still held in Cannon Beach each August. This workshop, which is attended by choral music teachers and college choral directors from around the Pacific Northwest, recently held a concert to honor Glarum.
