In today’s episode, Dr. Killeen reflects on a favorite quote from C. S. Lewis and how it applies to growth in dentistry, leadership, and life. Real change does not happen from a distance. Whether it is improving clinically, becoming a better leader, or building a stronger practice, progress comes from proximity. Staying close to good mentors, good thinking, and good systems creates momentum and makes growth feel possible instead of mysterious.

In this episode, Dr. Killeen reflects on an old photo and a powerful idea from psychology called the End of History Illusion. We tend to believe we are done changing, even though our past proves otherwise. Against a backdrop of rapid change and uncertainty, he explores why growth is ongoing, how future challenges shape future versions of us, and why staying open to change may be one of the most important leadership skills we have.

In this episode, Dr. Killeen challenges the obsession with time management and productivity. Being efficient only matters after you are clear on direction, because working hard in the wrong direction just gets you lost faster. He explains why regular reviews matter, how busyness can mask a lack of progress, and why direction, not speed, is the real measure of success in your practice and your life.

In this episode, Dr. Killeen breaks down the Zeigarnik Effect and why unfinished tasks are such a mental drain for practice owners and leaders. When work stays undocumented or unresolved, it quietly occupies mental space and fuels overwhelm. This episode explores how simple acts like writing things down, assigning tasks, and creating closure can free up energy and restore clarity without doing more work.

In this episode, Dr. Killeen reflects on a recent talk by Mark Costes and unpacks what overwhelm really is and why so many dentists are stuck in it. This is a calm reminder that busyness is not the same as effectiveness, and that sometimes the most productive move is to slow down, listen, and regain perspective. A thoughtful episode for anyone feeling stretched thin and tired of carrying constant pressure.

In this episode, Dr. Killeen shares a simple but powerful idea from James Clear about good habits versus bad habits and why leadership habits can feel especially unrewarding early on. From one-on-one meetings to building trust over time, this is a reminder that the habits that matter most often have a delayed payoff. If you’ve been showing up without seeing results yet, this one’s for you.

In this episode, Dr. Killeen reflects on a lesson from James Clear about why good habits are hard and why bad habits are easy. He connects that idea to leadership in dentistry, especially the habits that don’t feel great in the moment but quietly pay off over time. If you’ve ever wondered whether the effort you’re putting in now is actually working, this one’s a helpful reminder to keep planting the seeds.

In this episode, Dr. Killeen breaks down the Peak–End Rule and why it plays such a big role in how patients remember treatment discussions and make decisions. He shares a simple shift in how you sequence options and frame pros and cons that can dramatically improve clarity, confidence, and case acceptance. Small tweaks in the order of your conversation can make a surprisingly big difference.

In today’s episode, Dr. Killeen breaks business down to its basics: there are only two ways to build a healthier practice—grow revenue or cut expenses. The real challenge isn’t knowing that, it’s deciding which lever deserves your energy right now. Focus on one high-impact move at a time, instead of trying to do everything at once. Clarity, not complexity, is what actually moves the needle.

In today’s episode, Dr. Killeen talks about why so much stress comes from trying to control timelines and outcomes we don’t actually have power over. Instead, he shares a simpler—and more freeing—approach: narrowing your focus to the very next action. Progress doesn’t come from rushing the future, but from taking the next right step and trusting the rest will unfold.
