Noam
StudentThe tutorials given by Andres were always very engaging. He is excellent at bringing his enthusiasm across, making his classes not only educational but very fun as well. He had a lot of patience, happily explaining and re-explaining what we needed to understand, going above and beyond in that he sometimes supplied written additional material after the tutorials when needed. He is also great in creating a relaxed teaching atmosphere, so all the students felt very much at ease asking any questions.

ColleagueAndres is always approachable, patient and respectful. He is committed to his role outside of exercise classes and always available to discuss problems or answer questions. I am very comfortable recommending him for working with children online. He has shown the enthusiasm for teaching, the patience and the professionalism necessary for doing so.
