Chesca Colloredo-Mansfeld

Co-Founder & CEO

In co-founding MiracleFeet, Chesca saw the opportunity to bring the low-cost, non-surgical solution for a leading cause of physical disability to a global scale. Her background in investment capital, consulting, humanitarian aid, technology start-ups, and academia helped propel her into a successful social entrepreneur.

She first became interested in clubfoot while working at The University of Iowa. 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.

Originally from England, Chesca grew up in Africa and Asia before becoming a Morehead Cain scholar at the University of North Carolina at Chapel Hill, and later earning an MBA from Stanford University.
