Rachel Hamalainen

Rachel Hamalainen’s work is rooted in a conviction that philanthropy should play an active role in advancing social justice and more equitable communities. She helps organizations translate big ideas into practical, well-resourced strategies, bringing a calm, thoughtful presence to challenging environments. Clients appreciate her clarity, integrity, and unwavering focus on impact. 

As a Senior Vice President at CCS, Rachel partners with institutions across advocacy, civil rights, education, and social services to design and execute philanthropic strategies and campaigns ranging from $10 million to $1 billion. She advises executive teams and boards on major donor engagement, organizational positioning, and strengthening the systems necessary for long-term growth. Known for bridging high-level strategy with hands-on support, she helps organizations navigate moments of transition, opportunity, and scale. 

Rachel has devoted her entire career to philanthropy. Before joining CCS, she was a grantmaker at the Open Society Foundations, managing U.S.-based portfolios focused on money in politics, civic engagement, and democratic governance. This experience provided a 360-degree view of how funders and nonprofits can better align vision, strategy, and resources, a perspective she brings to every engagement. She has been awarded fellowships with the New Leaders Council, NYU Wagner, and I.G. Advisors and has served on boards at organizations focused on reproductive justice, progressive politics, and Finnish cultural heritage. 

Rachel holds an MPA from NYU Wagner and a BA from Amherst College. She lives in Queens, New York with her two cats. Outside of work, she is an avid reader, language learner, and concertgoer.
