I became CSM and CPO with Mitch Lacey as CST. All that I can say is that the courses were great and that Mitch besides being a great instructor he mixed the theory with is personal experience adding even more value to the courses. I recommend Mitch as a professional (Scrum and IT related) and mostly as a person (to go out and eat some pastéis de belém or the world best chocolate cake).
He is definitely the guy you want as an instructor. He is 100% dedicated to his classes and sticks with the values of Agile. In fact, I even saw him do some push ups with a student, during the class, just to show everyone that you shouldn't be late (Agile Principle: Respect)
