Been going there two years and mediocre experience as far as conditioning and discipline. Tonight my daughter was being promoted to green belt and had a sit in instructor with two of his students. My 13 year old daughter had to spar a 2nd degree black belt who sparred hard but with self control. She accidentally struck my daughter in the throat once not good but understandable because there are hazards associated with the sport. She then sparred a brown belt 16-year-old boy who was hitting and kicking hard. His sensei claimed he told him numerous times to take it easy and I saw several hard strikes from where I sat and finally stood up and said that's enough several times getting louder to get the attention of the "responsible" adults in charge of the class. I did say "take it easy jack***" to be sure they knew I had enough because I would not stand and watch my daughter continue being pounded on. The guest sensei then got in my face and told me how stupid I looked by making a scene and challenged me to a fight on the floor for defending my daughter. He took his certificates off Wittler's wall and left in a huff with the dojo owners after him to make peace. They stood outside and accused me of being drunk - which I was NOT - and talked about how there was no way that I am a Christian which is a word that is misused and attached to far too many things it shouldn't be. Christian tae-kwon-do . . . HA!!! By the way, one dad in the class told me he would have responded the same way and another told the guest sensei that his student/son was hitting my daughter too hard. The Wittler's were adamant in their defense of their guest but I am certain after I have cooled off that I did the right thing. I did not send my kids to the street to train and get in shape. I sent them to a controlled environment where I thought I could trust grown adults who bear and abuse the name Christian to try to profit.
