Canon Martin Green is a nationally-acclaimed choral conductor, vocalist, and organist who has served as the Canon for Music at St. Paul’s Episcopal Cathedral in San Diego, California, for over twenty-six years and been a leading figure in the San Diego musical community throughout that time. Immersed in the Anglican choral tradition since childhood, Martin grew up as a boy chorister at St. Paul’s, where he was a treble soloist for the visit of Queen Elizabeth II to California. As a teenager, he was appointed the Organ Scholar and subsequently as the Assistant Organist and Choirmaster. Since being named the Organist-Choirmaster at St. Paul’s Cathedral, he has taught the Cathedral Choristers (Boys Choir), the St. Cecilia Choristers (Girls Choir), and directed the Cathedral’s two mixed adult choruses, semi-professional and fully professional. He has recorded two full albums with the Chorister programs and prepared a small chorus of boys for the award-winning score of Australian independent film “Exitus Roma.” Under his leadership, the Choristers formed significant performing relationships with the San Diego Symphony, La Jolla Symphony, and San Diego Opera. One of Martin’s foremost principles is to create consistently excellent and expressive liturgy every week of the year: in San Diego he has established year-round weekly Choral Evensong and organ recitals and full Choral Eucharists during the program year. He oversaw the widely-praised full restoration of the Cathedral’s Aeolian-Skinner organ by the Quimby Organ Company.

Widely respected as a choral conductor, he is the Associate Music Director of the San Diego Master Chorale, Musica Vitale, and served for fourteen years as the Children’s Chorus Master for the San Diego Opera. He was a Co-Director and Founder of the San Diego Summer Choral Festival. He has also conducted as a featured artist at conventions of the American Guild of Organists and the Choristers Guild. In his position at the Cathedral, Martin has worked to expand the choral repertoire by championing the performance of new music by rising composers while also searching for forgotten music in need of advocacy from across the literature of western art music. He has been fortunate to study Anglican choral and organ music directly with masters of craft like Martin Neary, John Rutter, David Willcocks, and Arthur Wills.

In demand as an organ recitalist in Southern California, Martin has been a frequent performer with the San Diego Symphony and at the Spreckels Organ Pavilion – home of the world’s largest outdoor pipe organ. His work has been featured on NPR’s Pipedreams. As an organ consultant, he has worked on numerous organ projects in the region, including the instrument at the San Diego Symphony’s Irwin Jacobs Music Center. He has performed as a vocal soloist with all the major orchestras and professional choirs in San Diego County with a special focus in early music.

Martin has earned significant recognition as a teacher of Choristers and Organists. Many people who grew up in his choir have gone on to professional careers as professional vocalists and music educators. His former Organ Scholars have gone on to hold major cathedral and parish positions across the United States.

Martin and his wife, Molly, are both passionate about the arts and arts education. Molly enjoys teaching classical ballet, especially to younger children, and looks forward to exploring those possibilities here in the NY region. Their youngest children, Charles and Iris, both study music and dance and are keen choristers in their own right.

David Preston joined the cathedral staff in August of 2024 as associate organist/choirmaster. He is a graduate student at Stony Brook University, pursuing a masters degree in harpsichord performance with Arthur Haas.

While studying at Yale, he was organ scholar at Trinity Church on the Green in New Haven, and was previously organist and choir director at Holy Shepherd Lutheran Church in Haslet, TX.

David has also won several awards, including second and audience prizes at the 2024 Miami International Organ Competition, first prize in the 2022 RCYO competition, and first and hymn playing prizes at the William B. Hall Organ Competition in 2019.

Aside from his interests in church music and early music, David enjoys spending time at railroad museums, reading about music history and theology, and traveling.
