CARL SAUNDERS (FOUNDER)

I’m Carl, the founder of X8 Health. My journey began as a professional rugby player before serving as a Royal Marines Physical Training and Exercise Rehabilitation Instructor. Along the way, I faced my own challenges with serious injuries, which gave me a real appreciation for the importance of recovery and long-term performance. Over the years, I’ve trained and rehabilitated everyone from elite athletes to those recovering from surgery or managing chronic pain. To bring everything together, I completed a master’s in Osteopathic Medicine, allowing me to provide a complete approach—covering diagnosis, treatment, rehabilitation, and performance. X8 Health is the result of that journey: a place where I can help people from all walks of life recover, rebuild, and perform at their best.

X8 prides itself in delivering the highest level of treatment, encompassed with a strong evidence based practise studied at the highest level, for all patients from all aspects of life.

Now come and meet the rest of the team.
