What Parents and Athletes Are Saying

"Very highly recommended!! We’re so grateful we found Sambo7. Nikos Michaelidis is an outstanding coach. He has world-class technical knowledge and provides high-level training, of course — but a special thing that really sets him apart is the deeper respect, trust and empathy he cultivates. He helps athletes build even more confidence, focus, effort, and a strong mindset as a result. And he makes the hard training fun! My son started once a week, but soon asked to go several times a week because he enjoys it so much."
