I have worked with Grandmaster Petrotta since 2006. At the time I was a 4th Dan in Kukkiwon and was just starting a school in Belgium. He helped me get started and has been a steadfast supporter of my schools, which eventually trained some very good people (mostly expats in Belgium) who have since returned to their home countries. As someone starting out, I could not have asked for better. He is a rock-solid person of integrity. He will do what he says he will do. If I send him an email, he will respond that day. Although I am in semi-retirement, I still have my few students join the ISA and, though I have the right-to-recommend in the Kukkiwon, I still forward my student's requests for Kukkiwon Dan certificates through him. He does it faster and it is always correct. I believe he has a very good relationship with the Kukkiwon.
