With his guiding vision, the Golden Gate International Children’s and Youth Choral Festival has become part of the international choral environment, bringing thousands of young singers from dozens of countries to California for a thrilling series of performances and competitions. For 28 years he has led the San Francisco Choral Society to a robust position as a keeper of the traditional repertoire and an innovative force in the commissioning and performance of new works for chorus and orchestra.
Recipient of awards for conducting in Germany and Poland, Geary has also received the KDFC Music Educator of the Year Award and the Lois Blair Rawlings Educational Inspiration Award. Most recently (2023) he received Chorus America’s Michael Korn Founders Award for a lifetime of significant contributions to the professional choral art.

He has served as a clinician internationally and he has conducted in dozens of countries. His choirs have performed with symphony orchestras and opera companies and for many musical conferences and festivals, both internationally and here in the United States, and can be heard on recordings with many labels. Geary has prepared choirs for leading conductors including JoAnn Falletta, Helmuth Rilling, Robert Shaw, Kurt Herbert Adler, Edo de Waart, Krzysztof Penderecki, Herbert Blomstedt, Dale Warland, Kent Nagano, Michael Morgan, Michael Tilson Thomas, Ludovic Morlot, and Esa-Pekka Salonen.

Gramophone magazine has characterized his music as “stylistically adventurous in setting, but strongly beholden to conventional means.” SF Classical Voice describes him as “a composer with the skill and self-confidence to write music that is clear, direct, and at times even simple, but not at all simple-minded.” He has had residencies at the MacDowell Colony, Fundación Valparaiso (Mojácar, Spain), Ragdale Foundation and the Visby International Centre for Composers (Visby, Sweden).
Recent pieces include Spun Light, a “distanced” concerto written for Icelandic violinist Hrabba Atladottir and the Left Coast Ensemble, and Solstice Dreams, a work for large chamber ensemble premiered by Ensemble Ibis at the University of Miami. Upcoming is Adventure in the Air, a concerto for soprano saxophone and wind orchestra commissioned by a consortium of bands. The first performance took place in the fall of 2023 at Cornell University, with subsequent performances by other consortium members throughout 2024. markwinges.com
