Greg Guillon 

As a former national tennis player in France, Greg has always been passionate about helping athletes reach their optimum performance as he understands each athlete has its own unique array of physical and mental attributes. 


After graduating from the British School of Osteopathy in 2009, Greg set up his own private clinic in Chiswick, London, as well as working at one of the biggest gyms and tennis club in West London where he fine-tuned his skills treating the general public as well as sports people, from gym goers to professional athletes.

It is in 2016 that Greg had the opportunity to work with British Athletes at the Loughborough International as well as The Diamond League in Rome in preparation for the Rio 2016 Olympic Games. In 2020, he decided to launch PROSTAR PERFORMANCE

a platform of services for professional athletes specifically designed to optimise performance and reduce the risk of injury.

Combining years of experience working with athletes including Premier League football players and ATP Tour players as a performance therapist and consultant, Greg has developed expertise in dealing with high performance athletes' requirements.

As a performance therapist, Greg is interested in understanding the biomechanics of the athletes and its interactions with the athletes technical and physical abilities based on the requirements of their sport. Greg is qualified to address all types of musculoskeletal dysfunctions as he uses a wide range of structural, functional, cranio-sacral and visceral techniques to address these dysfunctions and optimise body movement.
