Steven Evangelista, Principal, Co-Founder

Mr. Evangelista, who calls himself a five borough New Yorker and who attended city public schools from grades K to 12, began working in public education in 1998 as a Teach For America corps member. Earning a bachelor’s degree in psychology at Georgetown University, he expected elementary education to be a temporary career stop but found it to be a calling. Initially opposed to charters, he began researching them because of feedback from parents, experience watching the system fail to serve students and the promise of the charter law.He attended several national conferences and visited schools in major urban areas to learn more before completing an independent study on a rationale for an urban charter school at Bank Street College of Education and then providing consulting to teams starting schools in other states. Mr. Evangelista earned an MS.Ed. from Bank Street College in 2001. In 2004, he completed Building Excellent Schools, a national fellowship designed to train founders of new charter schools. He holds passionate interests in baseball, popular science and being a great father.

William Harney III, Director of Finance

Mr. Harney earned an A.B. degree in Economics from Dartmouth College and an M.B.A. degree in Finance from Columbia Business School. After a career in banking and finance (and a dozen years of observing our educational system up-close through his two sons), Mr. Harney decided to apply his skills and experience in that educational system. He was excited to discover charter schools, something he had known nothing about. He met Steve Evangelista in late 2009, and shortly thereafter, joined the Harlem Link Charter School as its first Director of Finance. Somewhat philosophical by nature, Mr. Harney has become known around the school for quoting one of his favorite writers, Jimmy Buffett, most notably with his statement “I love my job!”.
