Marion Estienne’s expertise is in international business, creating the agile leader, as well as global leadership challenges. She develops leaders (along with their teams) to meet the demands of the global marketplace and to perform more effectively in an environment characterized by uncertainty, rapid change, and complexity. Hence, the need for leadership agility.

Leadership and developing leaders are her passion. She believes it is not possible to move forward as an organization without transformational leadership. She explored this theme in a radio program entitled Present Tense, Future Perfect on the Bold and Brave Media Global Network/Tunein Radio with guests who are experts in the fields of innovation, climate change, and technology.
Marion has been in the Boston area since 2007. She is a fluent French speaker with some German. Prior to returning to the US, she lived in Germany, France, and the United Kingdom. She is a dual citizen of the US and the UK. Her perspective on business is both multi-cultural and global. She applies a systems perspective when working with clients and encourages them to do likewise. As a facilitator, consultant, and coach, she has worked with executives and professionals from almost all countries in the European Community as well as with Russians and Chinese.
Prior to returning to the United States, Marion worked for Sundridge Park Management Centre in the UK. SPMC was part of the PA Consulting Group. She worked in the Leadership and Teams Cluster with such clients as British Gas, Volvo, UK, United Technologies, and Schindler Elevator and Escalators. One of her responsibilities was to support PA, France to develop their management development business using the tools and techniques of SPMC.

She subsequently founded her consulting practice in London, deLafayette, Ltd. Her clients included pharmaceuticals and diagnostics companies such as Roche and what was Smith, Kline, Beecham. She worked in France and the UK for Vivendi, Veolia, Total Chemicals, and Royal Dutch Shell. It was at this time she became interested in executive coaching and began her coach formation with Amadeus and the Middlesex University.
Upon returning to the US, Marion was appointed senior faculty in the Custom Solutions Team at the Colorado Springs campus of the Centre for Creative Leadership. She was a member of the design and delivery of CCL’s Advancing Global Leadership program. She missed her coaching practice, however, and decided to return to the East Coast to pursue a career devoted to developing her knowledge and skills in executive coaching.

This led her to Boston where she founded 3sixtyglobal which focuses on coaching leaders to develop their levels of agility according to the vertical model developed by Bill Joiner and Stephen Josephs. She quickly determined that this was a model of leadership development suited to the development of global leaders. She also keeps abreast of developments in the intercultural field by working for IOR Global Services with expat executives. Currently she is exploring the relevance of Neuroscience as it is applied to cultural differences. This would be a new paradigm for learning how to adapt when necessary to other cultures.
