Antoinette has been part of the Agile movement since working with some of the original Manifesto signatories in 1996. She spent several years as Agile team member developing software products. She has been an Agile mentor since 2005, then received coaching from Agile Coaching Institute in the US in 2009 to kick off her Agile coaching career as Team Coach. She was part of the first Enterprise Coaching cohort in the US in 2014 and completed her certification in a cohort in 2015. Since then she has focused on growing agility at the enterprise level. This is achieved both through the adoption of Agile and Lean practices, but more importantly by leaders at all levels growing their inner agility.

Antoinette collaborates extensively with the front-runners in Agile coaching and leadership world-wide to train and develop Team Coaches, Enterprise Coaches and Agile Leaders. She frequently leads classes internationally, both in person and virtually. She is a coach of coaches, through training and mentoring, as well as one-on-one coaching. She spends most of her time collaborating with leadership teams and Agile transformation leads, as well as more junior leaders like Agile coaches and ScrumMasters. Her aim is to grow agility in EVERYONE, and coaching others how to do it. In line with that aim she often helps organisations set up internal coaching competencies.

She is a trained professional coach and certified in Organisational and Relationship Systems Coaching (ORSC). Her forte is changing culture and growing high performance in leadership teams, including teams in conflict.

Antoinette is an accomplished speaker and regularly delivers talks and workshops on agility, leadership and transformation at local and international conferences.
