A year training under Dr. Robert Cialdini, the godfather of influence, changed Dr. Chris Phelps' entire business. In this episode, he shares why it can change yours too!

After building four fee-for-service practices, Chris hit a wall every dentist knows. Patients weren't saying yes. Team members weren't following through. Associates weren't using the skills he'd paid to teach them. The problem wasn't clinical skill. It was human behavior, and once he understood how people actually make decisions, everything shifted.

In this episode, Chris joins Peter and Ian to break down Cialdini's seven principles of persuasion and why they've become the most overlooked business skill in dentistry. They get into why logic alone never moves a patient, how the order you present treatment changes how many people say yes, and which single principle Chris says dentists botch the most, the one costing the profession billions.

Peter shares how he built each principle into his own practice, from new-patient gifts to reviews to the simple shift of sitting beside patients instead of across from them.

If you've ever heard "I'll think about it" and watched a case walk out the door, this one will change how you communicate for good.

HOSTS: Dr. Peter Boulden and Ian de Jongh

SPECIAL GUEST: Dr. Chris Phelps

In this episode, Peter Boulden and Ian de Jongh sit down with Dr. Chris Phelps, one of the few dentists personally certified by Dr. Robert Cialdini in the science of influence and persuasion.

Together they explore how behavioral science can transform case acceptance, leadership, patient communication, and practice growth. Chris shares the lessons he learned while rebuilding struggling practices during the financial crisis and explains how understanding human behavior became the catalyst for dramatically improving both patient outcomes and business performance.

• Patients make decisions emotionally before they justify them logically.
• Communication is one of the most valuable skills a dentist can develop.
• Presenting treatment from highest value to lowest value increases acceptance.
• Authority and trust work together to influence patient decisions.
• Commitment is one of the most powerful drivers of follow-through.
• Too many treatment options often create decision paralysis.
• Technology should support relationships, not replace them.
• Social proof builds confidence and reduces uncertainty.
• Small changes in language can significantly improve case acceptance.
• Understanding behavioral science makes dentists better leaders and communicators.
• Great patient experiences are built on trust, not persuasion tactics.
• Success leaves clues across every industry.
