Rita organized for and worked with Marshall since she met him in the 1980s. She has offered NVC training in Mexico, Brazil, Japan, Israel, many parts of Europe, Canada, and the U.S. She coordinated the early activities of the Center for Nonviolent Communication, and served on the Board of Directors for nine years.

Rita helped write the original documents for the certification  preparation and assessment process, served as the organization's first Certification Coordinator, retiring from that role in December of 2014. Subsequently, she continued to offer support and guidance to Assessors and Certification Candidates, exploring how to live and teach the values of self-awareness, self-responsibility, community, and social change, all of which encompass the spirituality which is at the heart of Nonviolent Communication.

Rita co-authored the children's book, The Mayor of Jackal Heights, which demonstrates the power of NVC empathy. Rita's experiences have  taught her that once we fully receive the healing power of empathy for ourselves, we cannot stop the natural flow of compassion to others, creating the loving connections we all yearn for.
