Testimonials
What our clients say.
I recommend Céline Thomas as a coach. She is competent, direct yet caring, and offers solutions and techniques that are easy to put into practice, never losing sight of the original objectives. Coaching with her produces very concrete results and changes.
Nathalie Lavielle · High jewellery international clienteling director, CHAUMET
Céline supported me in a group supervision cohort in 2023. The insights that came from the quality and relevance of her practice led me to explore and revisit my own work, in order to secure my stance as a coach. The pair Céline and Stéphane form allows a holistic and direct approach, with genuine care. I strongly recommend her support, both one to one and in groups.
Belinda MJ Brown, MCC · Executive coach and supervisor
I followed Céline and Stéphane Vallée’s paired supervision for two years. The complementarity of their approaches makes the sessions very rich, with the added systemic mirroring they use between them. They hold the safety that lets us share our doubts within the group of coaches. I warmly recommend their supervision!
Adelyne Albrecht · Professional coach
Thank you Céline for your support! I genuinely appreciated her approach: each time she adjusted to the state and the need of the moment. Great simplicity, real professionalism, a precise eye — and always with a smile.
