Chesca Colloredo-Mansfeld

Co-Founder & CEO

Driven by the idea that a newly accepted low-cost, non-surgical treatment could have extraordinary impact on the lives of children born with clubfoot in low and middle income countries, Chesca co-founded MiracleFeet in 2010. She successfully built on experience in investment banking, management consulting and technology start-ups to refashion herself as a social entrepreneur.

Originally from England, Chesca grew up in Africa and Asia, and has lived and worked in Pakistan, Ecuador, UK and US. She first became interested in clubfoot while working at The University of Iowa, where the Ponseti Method was pioneered. Drawn to the opportunity to have an impact on children’s lives in some of the countries where she had grown up, she joined a small group of parents and surgeons interested in creating an organization to address the long-overlooked issue of untreated clubfoot.

She studied economics and political science at the University of North Carolina at Chapel Hill as a Morehead-Cain scholar, and later earned an MBA from Stanford University.
