I am very happy to write a phrase that can explain or testify the important job that Mr Mark Hamilton has done.With the prime law, he has helped us to understand what we did not understand, to know what we did not know and to open our eyes in order to see what we cannot see. He is a courageous man, he did the best he could to teach us what was unclear for us, that’s why, I am very grateful to him, and I want to thank him for the great job that he has done. Thanks again, Mr Hamilton Efenor A.
