This document provides an outline for a presentation by Greg Riehl on working with marginalized populations in a global context. The learning outcomes include understanding Riehl's experience working with these groups, who he enjoys working with and what they have taught him, and memorable experiences that led him to embrace the Platinum Rule of treating others how they want to be treated. The presentation will describe the bronze, silver, gold, and platinum rules and hopes attendees can see patients and clients through a new lens.
