I attended the Washington DC bootcamp from May 8 to 12th. I signed up for this bootcamp because of the reviews and video testimonials from the previous bootcamp attendees and I was not disappointed! David Langer was our instructor. His teaching quality was exceptional. His real life analogies throughout the bootcamp assisted the learning. He has a thorough knowledge on the subjects he teaches and patiently answered all the attendees questions and clarifications – be it during the class or after.
