David provided training to my technical sales team and delivered an excellent, thought-provoking and performance-enhancing course. The material was delivered in a practical, engaging and fun way and without a doubt, improved the skills of my team. I would recommend David to anybody looking to use his services.

I was a student in a class taught by David for improving public speaking and presentation skills. His teaching style made me learn to have fun with public speaking instead of viewing it as something to fear. In addition to turning speaking into something that was enjoyable, he taught us techniques to use to make sure the audience attending the presentation would benefit from having done so. David’s teaching style led to a lot of student interaction and marked improvements in student performance throughout the class. Also, I left the class with plenty of take-away tips on public speaking that I still use to this day.
I highly recommend contacting David if your job involves giving presentations to customers or clients.

David is an outstanding trainer, careful well thought out lessons providing plenty of usage scenarios and hands-on experience. David has a knack for taking a complex subject and simplifying as much as it needs, and no further, which is extremely helpful when trying to digest wholly new concepts.

David is a gifted and talented trainer. I had the chance to participate in the official Asterisk course in Belgium. His knowledge, how to give courses and his enthusiasm makes David a trainer of great value. Any teacher could follow the example of his teaching methods and his unwavering enthusiasm. I had the opportunity to meet many trainers in my career. David is the best! David is excellent in all of his work. It was a great pleasure to meet him.
