Shane Martin, School of Education dean at Loyola Marymount University (LMU), has been named the new Board of Directors chairman for Green Dot Public Schools, the largest public charter school organization in Los Angeles.

Former Chairman Steve Barr will now be chair emeritus and take an expanded role in policy reform and improving public education on a national scale, according to Green Dot, headquartered in Los Angeles. Barr is not departing from Green Dot and he retains his title and responsibilities as executive board member and founder.

Green Dot CEO Marco Petruzzi will continue to run day to day operations while Martin will fill the role of chairman of the board.

“As a founding board member of Green Dot, I am honored to be named chairman of the board,” said Martin, who became LMU education dean in 2005.

“Green Dot has transformed the landscape of public education in Los Angeles and developed a national model for school reform.—It will be a privilege to work with board secretary Ted Mitchell and the rest of the board to build upon the work of Steve Barr.”

Green Dot representatives say that Martin has a strong background in education and is an expert in the areas of intercultural education, cultural diversity, and Catholic schools.

Martin is currently on the board for Loyola High School of Los Angeles’ Board of Regents, and Teach For America, Los Angeles.

Green Dot Public Schools was founded in 1999 by Barr with the mission of improving public education in Los Angeles. The organization has since expanded dramatically and for the 2009-10 school year it manages 20 schools, including 19 in Los Angeles and one in New York.

Green Dot’s goal is to produce a model for change that can be repeated on a national scale, Barr said.
