Michael Accardi brings a diverse and broad array of experience to his new role as Executive Director of MathPOWER, spanning more than fifteen years in the non-profit sector.  Throughout his career, Michael has been the architect of institutional and development strategies designed to grow organizations, and has played leading roles in their tactical implementation through program development and frontline fundraising.

Most recently, Michael served as Senior Director of Development for the National Brain Tumor Society, where he oversaw a diverse portfolio of donors and operations, and planned a $2.5 million capital campaign for pediatric research. Previously, Michael worked in various roles at Merrimack College in North Andover, Massachusetts, where he helped to design and implement the institution’s ten-year strategic plan, developing and resourcing signature initiatives for the College while growing fundraising revenues in the process.  Among his accomplishments are the College’s first-ever grant from the National Science Foundation, and $1 million in funding for a Center for Student Success.

Michael earned his Bachelor’s degree from the University of New Hampshire, and a Master of Public Policy from the University of Denver, where he wrote his capstone policy memo on the use of eminent domain for private economic development.  Michael lives north of Boston and enjoys quality time with his family and dogs as they partake in the many activities Greater Boston offers.
