Mr. Dumbra

Welcome to Mr. Dumbra's Website!

Hi! I teach science to all the sixth graders and two classes of seventh graders.  This is my third year at Venetia Valley, and I love teaching here!  Before I came to VV, I taught at La Entrada School in Menlo Park for 14 years (English, social studies, Latin, and science).  Go Falcons!
