David Ooi

Rehabilitation Specialist & Personal Trainer



David Ooi (@davidooibjj) is our Rehabilitation Specialist who graduated from University of Hertfordshire with a BSc in Physiotherapy before returning home to Singapore to practice. He initially studied Mathematics at the University of Warwick, and worked in analytics. However, he found himself wanting to work in a field where he can be more active, caring and healthy. This led him to pursue a new career in physiotherapy. 

David takes a systematic approach to injury rehabilitation, identifying the goals of his patients and letting that guide the development and implementation of a comprehensive plan to achieve them. David is a keen supporter and practitioner of Judo and Brazilian Jiu Jitsu, and has also won multiple titles in both disciplines. In addition to competing, David has taught both martial arts to a wide array of people, ranging from children and beginners to adult competitors, a passion which has also led him to a role within the Ultimate Fighting Championship (UFC). Working in close proximity to elite fighters has led David to develop a strong interest in the rehab, prehab, and strength and conditioning needs of combat athletes.

David has taken part in the world of competitive grip strength, and holds the prestigious honour of being the inaugural winner of ‘Britain’s Strongest Fighting Hands’.
