Founders & Staff

United by a passion for social justice & Michigan football, Scott Thomas & Sammy Politziner founded Arbor Brothers in 2009 and continue to co-lead it today.

  • Sammy Politziner

    Co-Founder

    Sammy graduated from the University of Michigan and moved to New York City, where he taught second grade in the South Bronx with Teach for America and founded a small academic summer camp for his students.  After a stint of world traveling, Sammy moved north for a master’s degree from the Harvard Graduate School of Education and then down south to teach at a KIPP school in North Carolina.  Sammy returned to New York for a job in investment banking at Kildare Capital, a boutique firm, where he spent five years providing sell-side M&A and capital formation advice. In addition to co-leading Arbor Brothers, Sammy serves as a director on the board of Exponent Philanthropy, the nation’s largest association of funders.
