Our story
Keynvor means ocean in Cornish — a nod to our director’s roots and to the values of flow, strength, and resilience that guide our work.
Our services are built for athletes and performance teams who want more than standard physiotherapy. We specialise in Be Activated, a system that resets movement patterns to optimise efficiency and power, accelerate recovery, and reduce pain and injury risk.
Alongside this, we provide manual therapy, movement assessment, breathwork, and strength & conditioning support. Whether through demonstrations, team clinics, or 1:1 athlete programmes, we deliver practical solutions that enhance performance and fit seamlessly into existing medical and coaching structures.
Our background
Founder
John Gripper — MCSP, Neuro-Muscular Activations Therapist and MSK Chartered Physiotherapist
John has worked across elite environments including Bath Rugby and Manchester City FC. He has over 10 years of experience practising at high-performance clinics, collaborating with specialists in rehabilitation, podiatry and performance medicine.
From big-wave surfers and footballers to Olympic skiers and snowboarders, John brings evidence-led physiotherapy and activation techniques to athletes aiming for the highest standards.
John has trained directly with Douglas Heel, founder of Be Activated. Experiencing Doug’s workshops — and the dramatic, immediate changes they produced — was a turning point in shaping John’s approach to physiotherapy.
That encounter continues to influence his work today, blending Be Activated with physiotherapy and performance principles to help athletes move and feel better, recover quicker, and compete with confidence.
He blends this with Connect Therapy by Dr LJ Li and ‘TINNL’ from Alison Taylor to be able to view the human body through a different lens than conventional physiotherapy. So if you’ve not got to where you want to with conventional physio treatment and rehabilitation, this can offer a totally different perspective as to why you are where you currently are, and a different strategy for how to get you moving forwards to a place of resilience and performance.
Inspired by Douglas Heel and the late great Louis Gifford, John has built his career on delivering world-class physiotherapy to athletes and active individuals alike.
