I had in the summer of 2012 the pleasure of attending one of Jacobs project management course incl. PRINCE2 certification. I have worked with project management for several years and needed some theory to practice. And I got it. Jacob gave me with his dedication and knowledge a lot of new tools and insights that can be used during your workday.
He was good at keeping focus while having a positive and humorous approach to sometimes heavy subjects.
I can give Jacob my best recommendations.
