"My practice has grown by 20-30% since joining. But that’s not WHY I joined, nor is it the BEST part. I joined to enjoy practice more, gain confidence in my communication and add functional testing. What I got is way more ease in my schedule, way more flow in my adjusting, a better understanding of my patient's needs, and an understanding of why valuing and prioritizing MY vitality has shifted my practice. All without changing a single procedure, just changing how I show up and serve each and every day."

Dr. Pip Penrose Young, Stratford, Ontario

"The key to moving our practice from one that was stuck and stagnant to one that is growing and thriving has been the vitality shift. The vitality shift got us moving and the vitality engine keeps us moving. The vitality engine has helped us develop our skills to communicate & practice congruently in a vitalistic manner. We’ve never been happier or more fulfilled in practice."

Dr. John and Marie Osborne, Ireland
