Heather McPherson

Heather McPherson is the summer associate at Impact Capital Managers. She joins ICM at the mid-point of her MBA at Duke University’s Fuqua School of Business, where she concentrates her studies on social entrepreneurship and strategy. Before attending Duke, Heather helped launch the Harvard Global Institute, a University-wide initiative to deepen Harvard’s international engagement and promote interdisciplinary scholarship on issues of global significance. Over two years, Heather supported the start-up of 15 projects involving 26 faculty across five Harvard Schools addressing topics such as climate change, education and youth development, health, public policy, and transnational relations.

Prior to Harvard, Heather worked in non-profit management, supporting the CEO and Board of Directors at the Boston-based nonprofit Horizons for Homeless Children. She began her career in public health consulting at John Snow, Inc. (JSI) in Boston, managing a portfolio of global health projects and supporting new business development. Her time at JSI included one-year as the country-based operations manager for the Timor-Leste Health Improvement Project. As Heather pursues her MBA, she is committed to a career path that aligns social impact and business objectives—the same commitment that drives members of the ICM network.

An avid long-distance backpacker and co-president of the graduate student outdoor club at Duke, Heather spends her time outside the classroom planning her next hike. Past excursions include the Teton Crest Trail, the King’s Trail in Sweden, and a trek to the 19,000-foot peak of Cayambe Volcano in Ecuador.
