For ten years, Mar worked as a university professor, teaching and researching on topics of human rights, philosophy, and religion. In her research, she found herself increasingly concerned about the brutal exploitation that takes place through human trafficking.

In 2011, Mar participated in a conversation of human trafficking experts who were advising a charitable foundation on interventions to prevent trafficking. The experts said that businesses were key to prevention yet were largely missing from the national response. BEST was created to fill that gap. As the Founding Executive Director, Mar educates business leaders and provides them with tools to implement socially responsible strategies that prevent human trafficking.
