I've worked with Coach Sjong for just under a year, remotely. I had been at a plateau for a few years, and with his help, I easily improved by 2 letter grades. This was despite an injury that I incurred during training, and to me, that's critical. He immediately understood the type of injury I had, and coached me through a phase of recovery which was longer than I would have done myself, but had me coming back stronger still. His training programming is excellent, and when combined with video and skype calls, he proves he has a knack for communicating the nuances of climbing technique and how to improve it. read more
