Mr. John Cerezo

Hello my name is John Cerezo. I'm currently a seventh grade life science/health teacher at Stevenson Middle School. This upcoming school year will be my seventh year teaching.

I attended Cal State Long Beach and graduated in spring 2004. I recieved a bachelors in Biology. In the fall of that year I attended Cal State Northridge and a year later received my teaching credential.

This will be my second year participating in IMPACT LA. I've been fortunate to work with Jose Zamalloa, as my fellow. I hope to spark an interest in my students to purse careers in STEM related fields.
