Executive Team

Yvette Marrin, Ph.D.
President and Co-founder, Board Member

Prior to becoming President of the National Cristina Foundation in 1984, Dr. Marrin was active over a long career assisting people with special needs and the underprivileged reach their potential through her work as a teacher, educational therapist, consultant, and school administrator. She earned a Ph.D in Organizational and Administrative Studies and Special Education from New York University in 1985.

Pioneering the concept of technology reuse on a national scale since 1984, as president of the National Cristina Foundation she dedicates her efforts along with the team and our Board of Directors to assure that the Foundation continues to evolve its mission that no technology should go to waste but be effectively reused to enable people in need to "link their lives to its promise."

Dr. Marrin’s belief that charities that believe in the productive and responsible reuse of previously used technology to help people in need has led to the creation and ongoing development of the Cristina Network. The Foundation’s innovative donation management system software is designed to significantly increase the number of participating partner organizations who can benefit from technology reuse. It greatly expands technology donation channels for potential donors to a broad range of communities in the United States and internationally.

Yvette Marrin is married to the award winning historian and author of numerous non fiction history and science books for young adults, Dr. Albert Marrin.
