Trevor Simpson is a resident of Vancouver, Canada and a successful business manager and consultant. His background was the world of marketing and advertising until 1991. From Executive Vice president of McKim Advertising, at the time Canada's largest advertising agency, he moved on to start his own consulting practice in marketing, communications and research. In the late nineties he started to explore opportunities that seemed more personally fulfilling and volunteered his services at the Centre for Integrated Healing (now InspireHealth) in Vancouver as a marketing consultant.

This experience opened a new chapter in his life as a writer and a teacher. He co-authored the book "Staying Alive - Cookbook for Cancer Free Living with Sally Errey to which he provided stories of cancer survivors' healing journeys. He started to teach decision-making to help empower patients with cancer at the Centre. This evolved in to a passionate commitment to assist others in the practice of conscious decision-making. He created the DecisionClarity model, which is the focus of his recent book titled "Life's Little Book for Big Decisions together with a companion CD. Recently he integrated the decision-making work into his practice as a spiritual coach.

In 2000, he received the Diploma of Personal Development from the Unity School for Religious Studies in Kansas City. In 2003, he completed the two-year Hollyhock program "The Art of Spiritual Guidance."
