Margaret Gonzalez, a musician and educator from Venezuela, is a product of El Sistema.  She grew up in the capital city of Caracas in Venezuela where she learned the core values of El Sistema, and how it has the power to create social change. Through these life experiences, Margaret developed a deep sense of being valued and how to confidently face the challenges of life's journey.  She knows first-hand what a difference this can make in one's life, and with a profound passion for teaching, is excited to share the same opportunities and experiences with the children of San Francisco.

Margaret earned a Bachelor of Music in Viola Performance and Minor in Violin and Piano from Shenandoah University (Virginia) where she was a student of violist Doris Lederer from the Audubon Quartet.  Prior to her studies in the United States, she performed with the world-renowned Simon Bolivar Orchestra of Venezuela under Maestro Gustavo Dudamel.

Angela Solis is a violin and viola teacher who began her musical studies in Spain where she earned a bachelor’s degree in music. During that time, Angela's performance and teaching experience was forged between classical, contemporary and regional styles. Her experience includes performing in many orchestras, ensembles, recording studios and as lead singer and founder of the band “Costellas”.  

One of her greatest professional achievements was obtaining the viola teacher position in the state music system in Spain. It is an arduous process that can take years to achieve; one must prove a high level of competence in performance, teaching skills and instrument- related knowledge. Angela earned the 6th highest score in the test that year.  At Music Mission San Francisco, she teaches violin.
