Cambridge, MA—Tiffany Cooper Gueye, CEO of BELL, has joined the Board of Directors of the Center for Effective Philanthropy (CEP), a nonprofit organization whose mission is to provide data and create insight so philanthropic funders can better define, assess, and improve their effectiveness—and, as a result, their intended impact. She has been elected to a three-year term, which began July 1 2013.

Tiffany started her career at BELL in 1998 and has served in a variety of roles, including program manager, director of evaluation, and chief operating officer of field operations. During her tenure at BELL, Tiffany has been a driving force in creating a data-driven culture of continual improvement at BELL. Tiffany became CEO in 2008, and through her leadership, BELL has grown to annually serve more than 12,000 students in schools across six states. BELL’s expanded learning programs, partnership model, and evaluation methods have become nationally recognized as best practices in expanded learning programs. BELL’s rigorous evidence has informed local and federal policy efforts aimed at increasing the role of expanded learning programs for at-risk students.

“Tiffany brings an impressive level of expertise to our board,” said Kathy Merchant, president and CEO of the Greater Cincinnati Foundation and chair of the CEP board.  “She is a respected authority on out-of-school-time learning, measurement, and evaluation.”

Tiffany is a recipient of Boston College’s Donald J. White Teaching Excellence Award and served as an instructor at Johns Hopkins University. She was recognized by The Network Journal and by The Boston Business Journal as a “Top 40 Under 40” achiever, and won the “Be the Change Award” from the Massachusetts Conference for Women.

She holds a B.A. in Psychology and a Ph.D. in educational research, evaluation and measurement, both from Boston College.

“Tiffany is an exceptional nonprofit leader,” said CEP President Phil Buchanan. “Her commitment to using data to drive decisions is going to be a tremendous asset to CEP and those foundations we work with. I’m looking forward to working with her over these few years.”

Tiffany Cooper Gueye will join a Board of Directors whose other members include: Phil Buchanan, president of CEP; M. Christine DeVita, former president of The Wallace Foundation; Crystal Hayling, principal at C2 Projects; Christine James-Brown, president and CEO of the Child Welfare League of America; James Knickman, president and CEO of the New York State Health Foundation; Kathryn Merchant, president and CEO of the Greater Cincinnati Foundation; Grant Oliphant, president and CEO of The Pittsburgh Foundation; Christy Pichel, president of the Stuart Foundation; Nadya Shmavonian, independent consultant to foundations and nonprofits; Vince Stehle, executive director of Media Impact Funders; and Anne Warhover, president and CEO of the Colorado Health Foundation.
