On today’s episode, Dr. Mark Costes sits down with longtime friend, business partner, and Black Belt coach Dr. Addison Killeen to talk about his brand-new book, The Shift: A Leadership Fable of Transition from Overwhelm to Focus. Addison breaks down the motivation behind the book, the real-life struggles that inspired its fictional characters, and why storytelling can sometimes teach business lessons better than a textbook. Together, they walk through the book’s core themes—from building core values to mastering systems and hiring the right people—and why these foundational principles can make or break a dental practice. They also dig into Addison’s past working with defense contractors and restaurants, how those experiences shaped his view of business, and why mentorship is one of the most powerful resources any dentist can access.
