I have trained in Japanese shotokan karate for over 40 years and I can assure you that Sensei Nina Chenault is a very knowledgeable instructor.She is a student of the late Sensei Nishiyama and received all her Dan ranks through him and Sensei Fusaro. She also has some excellent students who are capable senseis in their own right. Safe but demanding training.It looks like the couple of negative reviews were not from people who have ever been to the dojo. might be misposted.
