I will start off by saying I DO NOT TRAIN HERE. I am the significant other of someone who does. I have come here to be a spectator. I really enjoy this gym. First off, it is very friendly. Simpson Go and his father are two very humble and kind people. Sim has been teaching my boyfriend bjj for quite awhile now and he enjoys it very much. He goes Monday through Friday and comes home exhausted from working out every night! He is working his way up in the gym and I have observed how Sim is a very good teacher. He explains everything thoroughly before anything is done and watches all of his students and encourages their technique. I have nothing but good things to say about him, his father, and their gym.
