Why Keynvor?

“I’ve been seeing John for a few years, as I was struggling with range in my hips after 14 years of professional rugby.

The type of treatment John gives is unique: I can feel and see improvement within the session.

What is also great is he explains why he is doing things and how it’s connected to your issue.

I couldn’t recommend John highly enough - you won’t believe the difference it makes, until you’ve had a session with him. ”
