I believe so, must have some level of skill to be riding at his level. Must say that most of what I see of him though is on Katie Price programmes, lol!
My daughter used to train and him and he is a very good trainer. He will have a 'sit on' any horse and get them going really well. Certainly improved the horse we had at that time with his training.
I did a couple of clinics with him and really enjoyed them. I was having some issues in canter with my tb and he got the measure of me and the horse v quickly. Like someone else as said he will have a sit on and my horse looked like a different animal and the sessions put me back on the right track again (at last!)
