Denise Paech Consultant

Denise Paech helps others to become the leader they choose to be, so they can be authentic and at ease in whatever leadership role they take on. She knows that developing the confidence and competence of everyone to step into leadership is the key to making strong, vibrant, and sustainable organisations, families, and individuals.

Through coaching, training, and consulting, Denise supports individuals and groups through the more challenging journey of turning theory into practice in their own leadership arena, wherever that is in the world.

Her practice is underpinned by extensive work with a wide range of government agencies, businesses, schools and educational organisations, and individuals. She has substantial experience as a senior executive, business manager, consultant, and coach.
