In today's episode, Dr. Killeen uses a simple idea from 3D printing to highlight an important lesson for dentistry and leadership. In 3D printing, every layer needs support underneath it. If something tries to extend without a foundation, the structure fails. The same principle applies to building a successful practice. Mission, vision, and core values are not just words on a wall. They form the foundation that supports systems, team culture, patient care, and long term stability. Check whether the structure of your practice is truly built on something solid.
