Bogdan Vaida burst onto the training scene in 2009 using extremely old Powerpoint presentations. Luckily, two years later, he switched to experiential training and learning by using methodologies that he practiced devotedly in all of his training. Known for his no-nonsense approach to getting results, Bogdan has been told that he helps participants get their own "insanely practical insights."

What does he do? He travels around the world doing experiential training in fields ranging from video editing to personality typologies and trainer training. While doing this, he also manages his online courses, which have over 10,000 students from all over the world.
