My son and my daughter attended Mirai for almost 2 years and they have improved tremendously with their tennis. I am very pleased that I found Coach Donny. Since he handled my son, my son started to win tournaments. He is a very professional and pleasant man. The other coaches in his academy are the same. They are amazing at what they do and are very nice to kids. Kids are never bored, they always want to come back to have trainings! I highly recommend Mirai! They also have the best venue in town! At the Raffles Hotel, what else can you ask for?
