In this episode, Dr. Killeen kicks off with a surprising quote from C-3PO in Star Wars and connects it to a powerful insight from Viktor Frankl, author of Man’s Search for Meaning. The idea is simple but honest. Struggle is part of the human experience, and dentistry is no exception. From canceled appointments to clinical complications, tough moments can either make us cynical or make us stronger. Dr. Killeen explores how choosing our response to difficulty is what ultimately shapes us as leaders, clinicians, and people. While hardship is unavoidable, growth is always a choice.

In this episode, Dr. Killeen shares a simple but powerful analogy about investing in your home and how it reflects the way we build our lives and practices. Do you focus more on how things look from the outside, or how they actually feel on the inside? He explores the tension between external validation and internal alignment, especially in dentistry where reviews, awards, and peer recognition can easily shape decisions. Lead with integrity, build around your values, and choose the kind of success you can feel proud of when the day is done.

In this episode, Dr. Killeen reflects on a trend many dentists are seeing right now. Patients are still saying yes to treatment, but overall dollars are down. Instead of reacting with fear, he reframes the moment through the lens of steel. Before steel is quenched it is strong, but after it goes through intense heat and rapid cooling, it becomes even tougher and more resilient. Dentistry works the same way. Challenging cases, tighter schedules, difficult conversations, and uncertain seasons are the fire that sharpens your skills. When you lean into learning and build real clinical and communication competence, confidence naturally follows. Pressure is not the enemy. It is often the process that makes you better.

In today's episode, Dr. Killeen shares a simple learning strategy inspired by Richard Feynman that can level up your clinical skills, leadership, and systems. The idea is straightforward. If you really want to understand something, try explaining it in plain language like you are teaching a sixth grader. By choosing a concept, simplifying it, identifying gaps, and refining your explanation, you quickly uncover what you truly know and where you need to grow. Real learning happens when you can explain it clearly and simply.

In this episode, Dr. Killeen talks about the kind of learning that never stops. Not CE credits or classroom time, but the everyday growth that keeps us adaptable and relevant in dentistry. As materials evolve, technology advances, and patient expectations shift, staying open to learning is what keeps us moving forward. The biggest obstacle is often our own ego and the belief that we already know enough. The moment you admit you do not know something, is the moment real growth begins.

In today's episode, Dr. Killeen unpacks a simple idea that applies to nearly every corner of dentistry. One size does not fit all. From choosing the right crown cement for zirconia versus layered E.max, to selecting scanners like the iTero, to building a practice model that fits your personality and team, success comes from alignment not imitation. He encourages dentists to stop copying what works for someone else and start evaluating what truly fits their workflow, values, and goals. Test, adjust, and build a practice that works for you, not just one that looks good from the outside.

In this episode, Dr. Killeen shares why 3D scanning is one of the most powerful tools you can add to your new patient workflow. Using the iTero as an example, he explains how scanning goes far beyond crowns and bridges. It gives patients a clear, visual understanding of gum recession, occlusion issues, wear patterns, and bite changes that they may have never noticed. When patients can see what is happening in their own mouths and track changes over time, conversations become clearer, trust grows, and case acceptance improves.

In this episode, Dr. Killeen challenges the traditional view of intelligence. It is not just about IQ, speed, or memorizing information. The real measure of intelligence is whether you are using your skills and drive to intentionally design a life you actually want to live. He reflects on the quiet burnout many high achievers experience and invites you to pause and consider what you are building. Success without alignment can feel empty, and that a meaningful life does not happen by accident.
