Gerard Collignon Gerard Collignon is a psychologist (PCM), certifying master trainer, and executive coach. He began his working life as a youth worker before graduating as a clinical psychologist in 1982. Having discovered transactional analysis at the end of the 1970s, he found that Taibi Kahler's miniscript proved extremely useful and effective in mentoring as well as in preventing teenage crises and managing teenaged clients actively in crisis. In 1987 Gerard invited Taibi Kahler for the first official PCM seminar in France. Certified as a trainer in process communication since 1989 and a master trainer since 1995, Gerard has trained hundreds of trainers and thousands of managers. In 2011 he became the only second certifying master trainer in the world. In France, 2,030,000 people had been trained in PCM by June 2016. There are also more than 1,250 trainers and coaches certified by Taibi Kahler and by Gerard Collignon, and every year, 50 trainers and 50 coaches become certified in PCM. The original French version of this book was the result of Pascal Legrand's and Gerard's experiences in coaching. John Parr contributed new material to the English version, and Taibi Kahler provided mentoring, suggested corrections, and read the finished work to ensure fidelity to the model. Gerard is grateful to both of them for their contribution to achieving Parlez-vous Personality? Coaching with Process Communication. Pascal Legrand Pascal Legrand has been a coach in companies for twenty years and a supervisor of coaches. He is a member of the French Coaching Society and was a member of the society's certifying committee for five years. He studied transactional analysis for eight years through IFAT, the French Institute of Transactional Analysis, before becoming an NLP master practitioner and PCM certifying master trainer. He is also MBTI and Golden certified. Pascal has an integrative approach to coaching.
