My first time at Jack London Square #oaktown I promise to never complain about my commute #bikelove @castilleja_school #chemistry @castilleja_school 
Thanks Ira Remsen! Gators vs Gators
So many awesome students in one place... tough to describe how proud I am to know them 
#shp @castilleja_school Proud to be a Californian
