Senior Leadership

David Shapiro
CEO & President

David Shapiro is the CEO of MENTOR: The National Mentoring Partnership, the unifying champion for expanding quality youth mentoring relationships in the United States. Nearly 25 years ago, MENTOR was founded to build and activate a mentoring movement. Since then, the number of mentoring relationships has grown from 300,000 to more than four million. Under Shapiro’s leadership, the organization’s efforts to build capacity and scale innovation within the mentoring movement has been highlighted by the Social Impact Exchange, the Stanford Social Innovation Review, and Grantmakers for Effective Organizations. In addition, the U.S Department of Justice Office of Juvenile Justice and Delinquency Prevention selected MENTOR to establish and lead the National Mentoring Resource Center.

In 2014, research commissioned by MENTOR entitled The Mentoring Effect found that 1 in 3 young people are reaching adulthood without the benefit of a mentor. MENTOR’s mission is to fuel the quality and quantity of mentoring relationships to close that gap. MENTOR’s strategy incorporates policy expertise and advocacy, public awareness and mobilization. The organization advances quality mentoring by bridging research to practice, and developing and delivering standards, training and state-of-the-art tools.

MENTOR carries out this work in collaboration with its national network of affiliate Mentoring Partnerships and more than 5,000 mentoring programs and volunteer centers in all 50 states. MENTOR works extensively across the private, public and nonprofit sectors to ensure that young people have the support they need through mentoring relationships to succeed at home, school and, ultimately, work.

Shapiro was previously the CEO of MENTOR’s Massachusetts affiliate, Mass Mentoring Partnership (MMP). During his tenure, MMP launched Champions of Mentoring at Fenway Park, Highland Street AmeriCorps Ambassadors of Mentoring, Mass Mentoring Counts and the Bill Russell Mentoring Grants Program. MMP grew by 400 percent, increased state funding for mentoring, attracted federal funding and distributed almost $1 million in financial assistance, capacity building, and match activities to mentoring programs. The number of young people matched increased by almost 50 percent during Shapiro’s seven years at MMP.

Shapiro’s experience includes leadership positions with the U.S. Golf Association Foundation’s 10-year, $50 million grant-making initiative and the American Red Cross of Massachusetts Bay. He chairs the board of the Mass Nonprofit Network and serves as a volunteer leader with a variety of nonprofits, including America’s Promise Alliance and the National Human Service Assembly. He was selected for the Barr Foundation Fellowship. Shapiro is a husband, father of two sons, and mentor.
