Nathaniel Sims began training in the martial arts at the age of 11 as an extremely shy boy and has developed into one of AMAA’s finest instructors. Mr. Sims is a true ‘product of the system.’ Coming to AMAA as a quiet, mild-mannered child, not fitting in with many other sports or activities, he took to his martial arts training, and began helping with classes. Growing up in the martial arts helped instill in him confidence. “Nothing thrills me more than seeing a student progress & grow in character as they go up the ranks.”
Outside of the martial arts, Mr. Sims enjoys studying art and video games (he has even developed his own!).
