Not every leader wears a title. In most workplaces, the people who set the tone, steady the room, and earn trust are not the ones with corner offices, but those whose behavior speaks louder than hierarchy. Mentor Without a Title is a guide for professionals who influence without rank, showing how presence, consistency, and fairness carry more weight than position. Drawing on research, lived experience, and case studies, Michael Dunn demonstrates how real leadership happens in the moments others overlook. From giving feedback without pulling rank to setting culture from the middle seat, this book delivers practical strategies for leading across generations, roles, and environments. The message is simple but urgent: leadership is not granted by authority; it is proven by action.
