★★★★★Jackson JiangDecent place to send your kids for solid tennis techniques. Highly recommend, coach Hong is very nice.
★Andrew L'HuillierCoach Hong is nice, but the woman who runs the place was incredibly rude to my daughter. I'll never bring my kids back here.
★★★★★Jane JingMy son has been learning tennis at Hong Tennis Training Center since summer 2017. From the video you can tell that the coach did very good job. I am very happy for my son. The group classes are fun too. We travel from Virginia to here three times a week. Highly recommend!
★Sue FritzPlaying volleyball on the non-tennis courts. It's about 34 degrees outside and 40 here in the facility. There is a one-room restroom that is nice and warm. But I don't know how this plays follow any kind of code.
