Susan Benigas, Executive Director 

Susan’s work has spanned the gamut, from running political campaigns to serving in executive, senior management and consultant roles for organizations ranging from professional sports and media to healthcare technology and worksite health promotion. It was while president of a worksite health promotion company that she had the paradigm-shift leading to her life’s passion: She questioned the status quo approach to “wellness”—all too often to diagnose and medicate—as opposed to a primary focus on identifying and eradicating the cause of disease.

Prior to joining ACLM, Susan founded the not-for-profit The Plantrician Project and co-founded the International Plant-based Nutrition Healthcare Conference, showcasing the efficacy of whole food, plant-based nutrition in its ability to prevent, suspend and often even reverse much of the chronic, degenerative disease pervasive in the U.S. and in many countries around the world.

She serves on the board of directors for the American Board of Lifestyle Medicine, the True Health Initiative and the T. Colin Campbell Center for Nutrition Studies. Her experience and successful track record in the areas of organizational leadership, project management, strategic marketing, public relations, development, and Internet-based solutions design and development have helped to fuel the success of many organizations and endeavors. Bringing vision to life is what she does best.
