They attended the same prep school as Matt Damen and Ben Affleck.
The younger brother graduated from Cambridge Rindge and Latin. A public high school the same as Damon and Affleck. The older brother went to school in Russia.
Cambridge Ringe and Latin (CRLS) is a public school. Cambridge has lots of “low income” housing. CRLS is where the “low income” residents go to high school. It’s far more “inner city” than “prep”.
