Tom MendelsohnPhilanthropic Advising & Executive Coaching |
Tom and Julia co-founded MGA Consultants in 1999. They have each spent nearly forty years serving the nonprofit sector.
Tom has developed experience and expertise helping organizations plan and develop, and helping managers navigate the challenges of running them. For decades, Tom served a broad array of organizations, focusing particularly on strategic planning, board and organizational development, and executive coaching (see our past and current clients).
In 2018, Tom began work in support of Movement Voter Project, turning his attention to explicitly supporting political change, and doubling down on his work supporting social, economic and racial justice. He supported donors and donor organizers, encouraging investment in grassroots organizing and other impactful strategies nationwide, prioritizing swing state investment. Over these years, he helped generate millions of dollars of investment and learned from hundreds of passionate donors, organizers and staff and volunteer colleagues. He left MVP at the end of 2025, but remains close to and informed about MVP and movement orgs, and progressive politics broadly.
Over the past few years, Tom has further narrowed the services he offers. He focuses on leading MGA’s philanthropic advising and executive coaching practice. Now in the final decade of his career, he recently began working less than full time.
Before founding MGA, Tom spent nine years with the American Cancer Society – including as Chief Information Officer of its New England Division – and worked earlier still as a teacher and outdoor educator.
Tom graduated from the University of Michigan in 1984 and received his Masters in Management from the Heller School at Brandeis University in 1989.
