I’ve been fortunate enough to have been to three training courses led by Chris Bramley.
Besides the obvious pleasant and fun laced way of leading these sessions, Chris stands out by not only knowing the products very well, but also being fully aware of the widest scope in which the product could be implemented.
Maybe not directly obvious, but Chris is extremely astute in gauging the different levels of technical knowledge and understanding of people attending his courses, adjusting the tech level of his knowledge transfer seamlessly to a level slightly above the lowest common denominator where his playful and pop-quizzing style quickly draws the level high enough for it to be interesting and relevant to all.

In short, a very well rounded person technically, personally and didactically.
