About this podcast

Is it possible to influence a decision before you’ve even made a proposal?

In this episode, Patrick is joined by Dr. Chris Phelps, CEO of the Cialdini Institute. Chris isn’t just a teacher of persuasion; he’s a practitioner who used these methods to turn his own struggling dental clinics into high-profit powerhouses during the 2008 recession.

In This Episode, You’ll Learn:

They dive deep into the concept of Pre-suasion: the art of setting the stage for a “Yes.” From the specific wording on an intake form to the channel playing on the waiting room TV, Chris reveals how environmental cues shape our clients’ mindset.
✅ The “Proactive” Switch: How asking patients if they preferred to be “Proactive or Reactive” increased treatment acceptance by 33.5%.
✅ Environment Matters: Why playing CNN in your lobby might be killing your sales (and why HGTV’s “Fixer Upper” is the perfect primer for healthcare).
✅ The Team as Detectives: How Chris trained his staff to uncover “Liking” similarities (kids, tennis, hobbies) so he could build instant rapport.
✅ The “Cat and Mice” Analogy: A brilliant explanation of the difference between manipulation (control) and persuasion (internal change).
✅ Membership Models: How applying the “Costco Model” to healthcare overcame the scarcity mindset of retirees.

Your Ethical Persuasion Challenge

1. Audit Your Intake: Look at your intake forms or “contact us” fields. Are you asking questions that prime your lead for the mindset you want them in? (e.g., “Do you prefer quick fixes or long-term solutions?”)
2. Check Your Environment: Walk into your own office or look at your Zoom background. What “mindset” does it trigger? Is it sterile and cold, or warm and transformative?
3. Train Your Detectives: Ask your team to find one personal interest of a lead before you hop on a sales call with them. Use that intel to build genuine rapport.

Key Takeaways from This Episode

1. Pre-Suasion dramatically improves case acceptance.

Dr Chris Phelps explains how shifting a patient’s mindset before presenting treatment increases acceptance by over 33%, using one powerful question: “Do you prefer to be proactive or reactive with your oral health?”

2. Intake forms can double as influence tools.

By adding carefully crafted “this-or-that” questions, practitioners can ethically uncover patient values, financial preferences, urgency levels, and treatment expectations.

3. Your environment shapes patient decisions.

Sights, sounds, smells, and waiting-room content influence mindset. Dr Chris Phelps shows how controlling environmental cues leads to more relaxed, receptive patients.

4. Unity and co-creation increase loyalty and follow-through.

When patients feel involved in choosing the treatment path, they feel ownership — which boosts loyalty, referrals, and compliance.

5. Ethical persuasion solves internal team issues, too.

These principles don’t only change patient behaviour — they also improve staff performance, motivation, and alignment, reducing procrastination and resistance.
