Martin has given several group trainings that I have participated in along with a handful of colleagues. He has great results. Participants enjoy it. They continue to (voluntarily and at their own cost) come back to future trainings of his, and in my own experience Martin's trainings are of the highest quality. He also has that rare quality of really loving and caring about what he does so that he's sincerely trying to improve and craft his skill to be the best trainer and coach he can. I also run the company where he has given these trainings. The fact that I invite him back repeatedly (and will do so again) itself recommends him very highly.
