Managing Director

- Roberto Aponte
Roberto Aponte joined Bioneers full-time in 2007 as Director of Events and Program Management. He had begun working with us in 2002 as a freelance conference planner and since has become an integral part of the Bioneers family. Those who work with Roberto know him for his positive presence, open and soothing communication style and grace under pressure.
Prior to joining Bioneers full-time, Roberto had an impressive background in large-scale event production. For 12 years he worked for the Marriott Corporation where he developed many of his technical and management skills along with his strong business acumen. Subsequently, as an independent contractor, his unusual combination of production skills and talent for human relations converged to create a niche for large-scale technology-related events. Roberto’s stellar reputation in the event business has grown as a result of his high quality work ethic and the measurable results he has acheived while working directly with many of the key CEOs in the high-tech sector including Steve Jobs, Bill Gates and Larry Ellison.
Roberto has a Master of Arts in Business from the California Institute of Integral Studies which focused on bringing environmental sustainability and a social justice lens to the practice of business. Roberto’s thesis explored the presence of spirit in the workplace and how business, when conducted consciously, can propel the changes necessary during these precarious times. Roberto’s passion for the intersection and integration of these issues make him a natural fit for his new role as Managing Director with Bioneers.
Roberto was born in Bridgeport, Connecticut as the son of first-generation Puerto Rican immigrants. Despite being raised in harsh inner city conditions, his early experiences with nature showed him that the solutions to our man-made problems could be right-at-hand. He was a recipient of several outreach programs for underprivileged youth and is a living testament to the power of mentoring and socially progressive programs.

of relationships with partners and clients who implement programs under
its name.
Kim has been involved in community and social causes for over twenty five years, and as a child of a political family, has had an interest in public service for most of her life. She has held board positions with not-for-profit and public benefit organizations, and was a 2001 recipient of the City of Atlanta’s Phoenix Award for outstanding civic service. In Great Britain she was involved in the foundation of the Marketing and Strategic Policy Group for the British Labour Party, and worked on election campaigns in the 1980’s. During that time she was Chair of her local parliamentary constituency party, a city-wide representative and a national union representative for the British Actors Equity Association.
