Christos is extremely knowledgeable and is now working to straighten my legs to regain full functionality in both knees. He is certainly among the best, if not the best, sports physio working in London. It may take time and effort but certainly worth the investment. Worth consulting for any muscular and joint problems, particularly if you have been working out for some time and trying to cope with niggles. Christos is good at seeking the root of the problem and sorting it out.
