May 16, 2016…Washington, D. C., The Thirteen announced major changes to the young, critically acclaimed all-star professional choir with move of its administrative headquarters to Washington, D. C., and the addition of major, internationally known cultural experts to its roster of Board members.

Matthew Robertson, a Washington native, is Founder and Artistic Director of the Choir, and announced the decision to return to Washington, to enrich this already-vibrant cultural environment. Robertson received a degree in Organ Performance, as the Fountain Scholar, at the Oberlin Conservatory in 2010.

Robertson graduated from Walt Whitman High School in Bethesda, Maryland.  Mr. Robertson is also Director of Music at Bradley Hills Presbyterian Church, Bethesda, Maryland.

Robertson has conducted The Thirteen throughout the United States and on multiple recordings. Garnering praise from critics, The American Record Guide describes the Choir as having a “light and attractive vocal blend and excellent choral discipline.” The Choir has performed residencies at major universities and performed concerts throughout the country. With a passion for educating new audiences, the Choir also routinely coaches generations of musicians in high schools and colleges through masterclasses and workshops.

The Choir recently acquired the talent of cultural and business icons to serve on the Board.

She has appeared with every major European and North American orchestra under leading conductors.  She has 100 recordings to her credit and been nominated twice for Grammy Awards.

Previously, he has sung with the prominent Harvard Glee Club and the Handel and Haydn Society.

World-renown organist, Donald Sutherland, is Coordinator of Organ at The  Peabody Conservatory of Music where he was given the Excellence in Teaching Award by the Johns Hopkins Alumni Association in 1997.

Singer Source founder and owner, and native Washingtonian, Lisa Koehler, brings extensive experience as a singer where she received a Master of Music in Music Education from the Catholic University of America. She has sung with numerous choral groups including the Choral Arts Society of Washington and the Cathedral Choral Society.  Ms. Koehler launched Singer Source in 2004 to fill a void in support of choral groups with the best voice, skill and personality to complement the group.  She also served as Co-Chair the Advisory Council on Instruction of the Arts, Arlington County, Virginia Public Schools.

Noted educator and business woman, Pat Stocker, Ph.D., brings business acumen to the Board as well as an appreciation of music and the arts.
