I was lucky enough to be involved in (one of) the first DOS conferences and it was a brilliant experience. So good that we were all keen to repeat it a year later, and did with, I believe, even greater success! Wholly professional and soaked in warmth from start to finish Marta and Greg ensured that everybody involved, participants and, lucky me, the trainer, got full value from the extended sessions. DOS offer really valuable, pragmatic, meaningful days of training, with time - for once – for both substantial input, and participants to experience, enjoy, reflect on and really question the content. Great stuff from start to finish, DOS come highly recommended.
