About Mr. Grossman and Middle School Social Studies.When I graduated with a Master's, I spent several years teaching college. After teaching, I decided to go to law school with the thought that I would some day return to the classroom. I spent 15 years as a lawyer defending the City of New York. While I loved being a lawyer, I wanted to get back to teaching. I have taught at Northern Highlands Regional HS and Norwood elementary school. This will be my tenth year in Rochelle Park.
