J.R. is the favourite teacher of my son. They are friends. J.R. is a good psychologist and delicate person. He always finds connection with Andrew. Gradual and subtle J.R. leads him from simple to more sophisticated movements, and Andrew feels his new levels, his potential and upgrades his self confidence. It gives incredibly good results that always evolve into something new. Andrew always waits for these lessons and we, the parents, are thankful to J.R. for all that.
