Susan Friedman

Sue Friedman joined the Redwood Symphony Board in 2006. She currently serves as Chair for the Redwood Symphony Advisory Board which began as the Symphony Auxiliary.

During this time she has been involved in leadership positions in community, educational and youth volunteer organizations, such as CASA, Samaritan House Free Medical and Dental Clinic, Music School support groups and multiple PTA organizations. She was instrumental in establishing the San Mateo High School District Fine and Performing Arts Foundation.

She continues to be involved in the love of music, community and youth. She believes that music is the universal language shared by everyone, which should be used to bring community together.
