Until Edwin’s death in 2011, Sonia March Nevis and Edwin C. Nevis together led in the development of powerful techniques to transform organization and family interactions based on Gestalt theory. After studying with the originators of Gestalt therapy, they helped to found two of the most successful Gestalt training organizations in the world. Sonia Nevis pioneered the expansion of Gestalt therapy application, first to couples and families, and then to small groups and teams. To teach this work, she established the Cape Cod Training Program (formerly known as the Couple and Family Training Program), which for more than thirty years has drawn participants from around the world. Edwin Nevis was a creator of the Gestalt approach to organizational consulting, consulting to Fortune 500 companies, and writing Organizational Consulting: A Gestalt Approach and co-authoring Intentional Revolutions: A Seven-Point Strategy for Transforming Organizations, in addition to many other articles.
Over the years the Nevis’ theoretical advances expanded Gestalt theory.
They trained thousands of consultants, coaches, therapists, and leaders worldwide, transforming their effectiveness and, for decades, refined GISC’s approach to bridging personal and professional life so that each world can benefit from the strengths of the other. The Nevis’ participants have gone on to extend the development of new theory and practice and now form the core of GISC’s experienced faculty and Professional Associates. The values of optimism, generosity, integrity, and professional curiosity embodied by the Center’s founders have become the foundation upon which GISC now stands. Sonia continues to teach at the Center, to write and contribute to professional journals, and to serve on the GISC Board of Directors.
There have been many recent gains at GISC – continued advancements in GISC’s leadership theory, in research and projects for the Education Initiative, and successes in the Healthcare Initiative, as well as in our certification programs. In 2011, GISC launched a new coach training program, the Competency Development Program for Coach Certification, now accredited by the International Coach Federation, to round out our professional certification and continuing education offerings for a variety of practitioners, from psychotherapists to OD practitioners.
The future remains bright for GISC. Sonia's and Edwin’s influence remains in the programs we teach, and the faculty that teaches them. And Sonia is still deeply involved in the Center’s programs and administration. The Center’s leadership remains in good hands and long-term sustainability continues to be a priority. Following the leadership succession plan that was put in place by the board of directors in 2006, Nancy Scott Hardaway, MEd, served as President and CEO from 2007 to June 2010, followed by David Tunney, MA, who served as Executive Director for the next two years, helping to grow GISC programs and services. Mary Anne Walk, MS, MBA, MCC, was appointed in June 2012 and, during her tenure, continued to support the mission of the Center by expanding GISC’s reach to even more organizations worldwide, and enhancing the financial position and operational performance of the Center.
Gwynne Guzzeau, MS, JD, took over as Executive Director January 1, 2014. Guzzeau, a GISC faculty member and Professional Associate for several years, has worked in education, law, small business and held public office, bringing a broad range of experience to her leadership of GISC.
GISC and its ongoing success continues to be a living testament to the passion and creativity of Sonia and Edwin Nevis and the legacy they began and that continues today.
