Our Founders
Katherine and Kimberly Corp
Most identical twins split in the first week after conception — before the body has decided which side is right and which is left. Katherine and Kimberly Corp split in the second week. By then, left and right were already written into the embryo. When it divided, each half inherited the opposite orientation.
One sister's dominant hand is her right. The other's is her left. They are not copies. They are reflections — and that biological fact became the foundation of a teaching philosophy.

Our Values
What guides the PAI community
Four values shape how we teach, mentor, and support every educator.
Challenge
We believe growth lives just outside comfort. Our curriculum is rigorous by design — because the instructors our students become will be asked hard questions by complicated bodies.
Motivate
Teaching is an act of sustained belief in another person's potential. We train our instructors to see what a student is capable of before the student can see it themselves.
Encourage
PAI was built in part because our founders experienced what it feels like to be made to feel wrong in their own bodies. Encouragement here is not soft. It is structural.
Inspire
The goal has never been to produce instructors who teach the way we do. It has been to produce instructors who teach — with rigor, with curiosity, and with a genuine love of movement.
Global Network
Fifty centers. Six continents. One curriculum.
PAI's satellite network spans the globe — but every center teaches from the same foundation: comprehensive, apparatus-based training built to the highest international standard, wherever in the world it's delivered.
