More about Catherine Testa

After obtaining her Master's degree in Environmental Science and Engineering from the Université Paris 7 Denis Diderot in 2006, Catherine Testa spent almost ten years advising major corporations on their transformation.

Dividing her life between New York and Paris and exploring the world, she decided to change course to co-create, alongside Olivier Toussaint and Monika Jouan, the media loptimisme.com in January 2016. This site dedicated to optimistic content quickly became a success, gathering over 200,000 subscribers on social networks in less than a year.

In addition to this, Catherine Testa co-founded the CHO (Chief Happiness Officers) Club in 2017 and authored the book "Osez l'Optimisme!", published in April 2017 by Éditions Michel Lafon.
