About

I'm Matthew Geddie — PhD, occupational therapist, and behavior change researcher. After three decades studying how people navigate major life transitions, I built ChangeEight to fill the gap most retirement planning ignores the psychological, social, and whole-life side of what comes next. ChangeEight is built on the 8 Dimensions of Retirement Wellness combined with Prochaska's Transtheoretical Model of Change. The research on what actually predicts thriving in later life already exists. Most people never see it. My goal is to change that. If you're within five years of retirement — or already there — this is for you.
