Her work sits at the intersection of systems thinking, behavioural insight, and practical communication. She supports people who need to make good decisions, maintain relationships, and keep moving forward when the stakes are high. Marcie works with people who have to keep functioning well together when the stakes are high, emotions are real, and the consequences are long-term.

She is a best-selling author, consultant, award-winning coach, and speaker specialising in trust, communication, and decision-making under pressure. Her work supports leaders, teams, executive partnerships, and parents operating in complex, high-stakes systems where relationships must continue, and decisions cannot fall apart.

All of Marcie’s work is grounded in the High Trust Teams Method - an evidence-based, repeatable approach to building trust, clarity, and sound judgment under pressure. The method was originally developed in high-stakes family systems, including conflicted co-parenting relationships, where emotions are intense, the relationship cannot be exited, and short-term fixes often create long-term damage.

That foundation now supports leadership teams, executive partnerships, and organisations navigating complexity, growth, and sustained pressure - environments with strikingly similar dynamics.

Marcie’s work focuses on how people think, decide, and repair together. It prioritises regulation before resolution, system-protecting decisions, clear boundaries and agreements, and rapid rupture and repair when trust is tested.

Her methodology is research-informed and rigorously practical, shaped through years of applied work rather than theory alone. It focuses on what actually works when emotions are present, and the cost of getting it wrong is long-term.

Marcie offers speaking, leadership and team engagements, 1:1 and alignment coaching, and specialist co-parenting work through The Co-Parent Way.
