Together with Artistic Director, Ian Robertson, she has worked closely with the San Francisco Symphony and in many different productions with the nationally acclaimed San Francisco Opera. Ms. Clark has performed and toured with her chorus at numerous festivals including the Grand Teton Music Festival. A highlight of her career was an invitation with the San Francisco Boys Chorus to sing at the inauguration of President Barack Obama in 2009.

In addition to her work with the SFBC and SFCM, Ms. Clark is currently the middle school music teacher at the Hamlin School for Girls in San Francisco. Over the past 11 years, she has created and established a choral program that now is a hallmark of the Hamlin School. Each week, over 100 students voluntarily come to rehearsals before school to sing in the chorus, and many of her former students have continued to sing in vocal ensembles after graduating from Hamlin. Ms. Clark’s choruses have consistently earned Gold medals and Unanimous Superior rankings at festivals and choral adjudications. In 2016, the Hamlin School Chorus was invited to be a showcase performance ensemble at the National Association of Independent School Conference in San Francisco.
Although a native to the San Francisco Bay Area, Ms. Clark has worked extensively with children’s choirs in Ohio, New York, and Japan and is a presenter and clinician for choral festivals and workshops. She earned her B.M.E. and M.M.E in Music Education from the Oberlin Conservatory and has studied choral conducting with Robert Shaw, Rodney Eichenberger, Henry Leck, and Doreen Rao. Coming from a family of educators and musicians, Ms. Clark is passionate about instilling a love for singing and music in children and is committed to helping each student develop as a musician and a performer.
Margaret Nomura Clark said, “I am honored and very excited to be selected as the Artistic Director of the Children’s Chorus of Washington. This is truly a dream come true as I have followed the Children’s Chorus of Washington over the years and am very aware of the standard of excellence and achievement established by Joan Gregoryk. My experience with the San Francisco Boys Chorus and my years in music education has prepared me for this next adventure, and I am looking forward to leading the Children’s Chorus of Washington in the next chapter of its development.”
