Social Proof from Rebecca Dash

I joined Martin's weekend course quite late (the night before if I recall rightly!) but from the outset he was very helpful and communicated clearly. The course was made up of around 5 attendees and we were taken through the Scrum Master certification training at a good pace that allowed us to digest the breadth of information we were being given in the space of time we had (2 days). I would recommend Martin if you want to train to be a Scrum Master.
