Perfect! For the introduction with me and my son, Yannik’s attitude was as we’d hoped. Yannik was clear and concise with his approach and method but most of all he was able to connect with my son as others haven’t and implemented my son’s interest and enjoyment of soccer to support math concepts. My son is excited for upcoming sessions and look forward to working with Yannik. Jackpot to us and highly recommend
