GM Petrotta,
      Once again thank you for your time and efforts helping me receive my 4th dan. I am very fortunate to have found you. I was getting close to my testing date for my 4th dan and I was nervous that I would never have the opportunity to get promoted. I found you and all my worries were over. I have not tested for a belt in 3yrs so I forgot how awesome it is to test. I am also very impressed with how quick the certification process went. I believe it was less then 3 weeks and now I am in the Kukkiwon data base. Thanks again for all you do in the martial arts community!

Sincerely,
Master Gregory A. Pothier
