One parent, Scott M., shared that his son started taking TaeKwonDo lessons from Mr. Joe at age 5, that the experience has been great, that Mr. Joe’s teaching goes far beyond physical conditioning, and that their son has matured far faster than he would have without JSK TaeKwonDo. The same parent also described a family atmosphere, said their son is “hooked,” and noted that their daughter started at the school as well, ending with “Recommend!” Last updated January 9, 2026.
