Zack Petersen

Zack Petersen is the Founder & CEO of the 1000 Days Fund, an NGO run by activists and driven by the unrelenting belief that the only true scalable solution to stunting prevention is to provide mothers with access to trained and confident community health workers. In just five years, 1000 Days Fund has trained 54,000 CHWs and facilitated more than 480,000 in-home malnutrition screenings, slashing stunting rates by as much as 55% in 1000 Days districts. Prior to founding the 1000 Days Fund, Zack worked for the World Bank. He is a graduate of the Fletcher School of Law and Diplomacy and served proudly as a Peace Corps volunteer in Mauritania. Originally from Iowa, Zack lives with his wife and their three girls—Audrey, Sienna, and Emma—in Bali. They enjoy making salsa, searching for starfish at low tide, playing the NYT Spelling Bee, and cracking dad jokes.
