Karen Mac is a seasoned communications strategist committed to helping mission-driven organizations ensure that their important work gets the visibility it deserves. She partners with senior executives, nonprofits, and foundations on executive communications, thought leadership, and communications strategy. 

After years working across nonprofits and philanthropy, Karen saw a consistent pattern: organizations doing vital work without the communications capacity to share it widely or strategically. She founded Karen Mac Communications to help organizations get the visibility needed to raise funds, grow their programs, and achieve greater impact. 

Most recently, Karen served as Associate Director of Communications & Marketing at FSG, a social impact consulting firm that advises leading foundations, nonprofits, and companies. There, she advised and supported over twenty Managing Directors and Directors on executive visibility and public-facing communications. Her work drove recognition across leading sector outlets including Devex, Inside Philanthropy, and Triple Pundit and tripled executive speaking opportunities at national conferences, podcasts, and high-profile convenings such as Social Innovation Summit, Facing Race, Council on Foundations, FORTUNE Brainstorm Health, and more.

Prior to FSG, Karen worked as a strategic communications consultant advising senior executives and nonprofits on messaging, thought leadership, and campaigns. Her client and organizational experience includes FSG, Acumen, Miller Center for Social Entrepreneurship, Paid Leave for the U.S. (PL+US), the Center for Urban and Racial Equity, NYU-CUNY Prevention Research Center, Gradian Health Systems, and Grammy-nominated musician Hollis Wong-Wear’s boutique creative studio hww.work.

Previously, Karen also worked in the international development sector for organizations such as Acumen and Miller Center for Social Entrepreneurship. She holds a B.S. in Public Health from Santa Clara University.
