The Mentorship That Most Airway-Focused Providers Want…But Rarely Get

Tired of airway theory and not enough personal, practical case by case guidance?
Whether you treat children, teens, or adults, you deserve real mentorship that helps you diagnose and treat airway-first cases with clarity and confidence.
Ask questions about the support you can expect, the skills you will gain, and whether one of the mentorships — E.C.H.O. (Early Childhood Health-centered Orthodontics™) or E.R.R.S.™ (Extraction Retraction Regret Syndome™)— is the right fit for you.
Dr. Bill Hang has spent more than forty years challenging traditional orthodontics. After realizing early in his career that extraction and retraction were harming patients, he spent decades studying with global leaders, treating thousands of airway friendly cases, and teaching hundreds of CE courses. He now brings that experience to clinicians who want practical, hands on mentorship.

This Community Exists For Airway Providers Who Want To Go Beyond Theory and Build The Practical Skills Necessary To Give Patients The Outcomes They Deserve.

Most of the providers who join Dr. Bill Hang’s mentorships have already taken more than enough airway related CE. But many still feel unsure when it comes to applying airway first techniques in their practices. That gap between theory and practical application creates a confidence crisis that leaves providers frustrated while their patients continue to struggle with mouth breathing, poor sleep, under development, pain, and long term health issues.
Dr. Hang created this community to close that gap so you can treat airway first cases with clarity, purpose, and confidence at every stage of life.
See if you are a good match for one of the mentorships — E.C.H.O. or E.R.R.S.™ — and whether the community, pace, and support level fit the way you practice

Two mentorships designed for dentists, orthodontists, and pediatric dentists who want practical, hands-on support for airway related cases.

E.C.H.O. is for providers who treat children in early childhood through the primary dentition years.
E.C.H.O. focuses on early airway protection, forward facial growth guidance, and supporting long-term airway health in developing children.
E.R.R.S.™ is for providers who treat teens and adults with airway, TMJ, sleep, or facial growth challenges.
E.R.R.S.™ focuses on reversing the effects of retraction or extraction treatment, restoring airway volume, and improving facial balance and function.
Understand whether E.C.H.O. or E.R.R.S.™ is the right mentorship for your patients and your practice.

A Personal Note From Dr. Hang

A Message From Dr. Bill Hang
“I created these mentorships because clinicians were doing their best but still didn’t have the guidance they needed for airway-first care. It’s the mentorship program I wish I had when I was learning.”

 — William M Hang, DDS, MSD

Ask your questions, understand the commitment, and choose the mentorship, E.C.H.O. or E.R.R.S.™, that aligns with your purpose and your patients.
