Yvonne Collier, Maddison Training

Yvonne is a master facilitator, coach and learning and development specialist. She is passionate about helping people become more assertive. Her definition of assertiveness is to balance Advocacy (the ability to speak up) and Empathy (to understand the feelings of self and others) under the umbrella of Respect.

She helps timid people stand up and speak up and bullies to develop more empathy.


Yvonne coaches 1:1 and runs in-house company programs through Maddison Training. She runs public courses in Sydney: two days and one day with Sydney University Centre for Continuing Education and half days with North Sydney Chamber of Commerce.

Enjoy Yvonne's experiential learning style, that's practical and inspirational, outcome focused and fun filled, as you become more confident and expand your 'assertive skills' tool kit.
