I made superb experiences with David, as he is a very professional and enthusiastic trainer, who really loves to learn something new from his students as well. His class were not setup as the one which are mostly known from school, as he uses different types of media such as audio and videos, as well as different techniques of learning. His teaching does not follow the classic patterns of ordinary school lessons. David knows how to get his students' attention by addressing their needs (eg, topic suggestions, interests), preparing them for the next session and then discussing them in the following sessions. David is always very interested in exploring topics that are new to him. David convinces during his presence with his inner peace, his consistently positive charisma and his high self-motivation. It has always been a great pleasure for me to see and work together with him to further improve my skills. Thanks and all the best, Patrick
