„I have been having a chance to co-operate with Joanna for almost 3 years. She helped us in very effective way to coach key people in our organization to expand theirs capabilities. I am receiving very positive feedbacks from our staff regarding her workshops and case studies. I had an opportunity to work with her very close in the past. Joanna was the only person who helped me realize the real change which has happened after my previous promotion. She was very professional and frank with me.”
