Marissa Matthews was a Montessori child from ages 2.5-11. She studied opera as an undergraduate and received a B.A. in Music from UC Berkeley.  After a couple years teaching English in Japan, she found her calling and came back to Montessori. She now holds an AMI diploma for ages 0-6 from the Montessori Institute of San Diego and a M.Ed. with a Montessori specialization from the University of San Diego. She still loves music and sings with the Oakland Jazz Choir. She is also learning to play the ukulele, which the children in the classroom greatly enjoy. She has two children of her own and loves to spend her time with her family singing, gardening, and camping. She joined TRIS in 2016.
