Hi i am heather polovsky from dance with butterflies here to tell you about how special jon is.i had just lost my personal trainer when i met jon in October in 2008. when i first met jon he was teaching his koga class in the basketball court. each time i came to koga jon would train me 1 on 1. by the third weak. i had learned so much from him. every good weak at weight watchers i had thanks to his help. i am not diabetic because of him. i was able to do the whole entire class without any help. he made sure he brought in a dvd for me to buy from him for my charity event. everybody that saw his dvd in the basket couldn't wait to buy raffle tickets just to help out my charity event.
