Sylviane is one of the pioneers of coaching in Belgium – with thousands of hours of coaching, and among the first MCC coaches in Europe. Early 2024, she is still the only French-speaking coach to hold the triple accreditation: Master Certified Coach by ICF, Master Practitioner by EMCC and Accredited Supervisor ESIA by EMCC. And she is one of the 15 supervisors in the world to be trained at supervision for team coaches.

She started by adopting a “coach attitude” while training executives (1994) and when mentoring and teaching students at the university. She started to coach executives on an individual basis early 2000 and continued coaching teams. She launched her first supervision groups in 2006 after discovering the systemic supervision offered by Alain Cardon and intensified her supervision skills with CSA. She has supervised and mentored hundreds of coaches in Belgium, Russia and around the world. In Russia, Sylviane has been training and supervising coaches since 2012 and two of her books are available in Russian. Since 2019, she is operating mentoring with a coach attitude via her company MentoringCo in China and around the globe. She is also the President of the non-for-profit organization GO-TKM dealing with the transmission of tacit knowledge across generations.

In 2010, she was Vice-President of the International Coach Federation (60 000 members in 140 countries) and part of the Global Board between 2008 and 2010. Between 2014 and 2016, she has been one of the five members of the Regional Advisory Council of the ICF for the EMEA Region. Today, she is an assessor for EMCC (individual and program accreditations).

She is the author of several books, including ‘Mentoring with a Coaching Attitude’ published by Open University Press/McGraw-Hill and co-authored with Fisher Yu and Cicero Carvalho, and ‘Coaching Excellence’ published by Lid Publishing London and co-authored with Viviane Launer.
