Rebel story
Coming from three different backgrounds Lian Ka Tjoa , Sandra Walthes & Arnout Vos all shared the same experience and drive of contributing to the world through developing better leadership. We all experienced, and had a strong view on what it means to be a ‘great’ leader, and the challenges people face in becoming this.
The REBEL founding team has a unique mixture of experience & expertise; Lian Ka Tjoa as an executive coach on personal development and becoming more conscious. Sandra Walthes as a Learning & Development expert. And Arnout as a Strategy Consultant, in leading teams, and advising boardrooms of large corporates on developing & implementing strategies that work.
Sandra and Lian Ka worked together on an executive Leadership program for Accenture in 2017, and already felt they wanted to build upon this. Lian Ka and Arnout met through a chance encounter in the summer of 2018, and she asked him to join in order to create a Millenial leadership program. After the first edition in May 2019, Sandra decided to take a step back from Rebel Leadership after having helped to set it up.
In the next five years Arnout and Lian Ka trained over 100 leaders and built a strong portfolio of clients and co-facilitators. In 2024 Lian Ka felt she wanted to refocus her energy amongst others on her individual coaching practice Love for leadership.
Since then Arnout is the owner of Rebel Leadership, still working with many talented coaches to deliver Rebel Leadership’s mission; To move people to REBEL for what they believe in, to create the change the world craves.
