I am a member of the Brice Road branch of the Oriental Martial Arts College, and I work with Grandmaster Choi a lot in the school. He is always patient and fair with me, even when I make mistakes (and I have made some big ones). I have been taking classes from him for over a year in Kimoodo, which has improved my health immensely. Just the loss of 140 lbs has made a major difference in my life. Master Choi has had to correct me, cajole me, and keep me going at times. He has always been there for the students and his track record of successful students is impressive to say the least. He is running a business, and at times he has to be the businessman, but I have seen him bend over backwards to assist his students. I now work on his computers and electronics to pay for my classes.
I know John Petway from the OMAC. John was on a work to study program, cleaning the Dojang and he did a very nice job cleaning. What happened between him and the ladies of the OMAC I have little knowledge of, but I do know these things are not pleasant and are always messy.
If anyone would like to see one of the students (and GM Choi's son) doing an impressive demonstration, look at this:
Oh, and John also has a comment on there.
