Why This Book Exists

The most expensive problems in dentistry aren't clinical. They're conversational.

In over 38 years inside dental practices, Tammy Duncan has rarely found a clinical problem at the root of a practice's struggles. What she finds — consistently — are gifted clinicians leading teams that are linguistically unprepared for the most important conversations they have every single day.

One lost new patient per day. At a conservative $1,500 lifetime value. That is $375,000 a year. Walking out the door. Before the patient ever walked in. And nobody in the practice had any idea.

— Tammy Duncan, Four Minutes and Seventeen Seconds: How One Conversation Changes Everything in a Dental Practice

The fix is not a script. It's not a seminar. It's not a new software system. It's a complete communication transformation — built into the daily rhythm of your practice — that gives every team member the words to build trust at every single touchpoint.

That system is A.L.I.G.N.™ — and this is the book that teaches it.

Everything your practice needs to communicate differently — starting Monday
