Aikido Diamond State
Stefan and John's black belts are registered both at the Aikikai Honbu Dojo in Tokyo and The United States Aikido Federation. John Hadfield began his study of aikido in 1993 under the Rev. Zenko Okimura. He has a background in boxing, wrestling and judo, has practiced several styles of aikido, and has been teaching aikido for more than 20 years.

John's classes reinforce the importance of the basic principles of aikido awareness and posture, breathing and relaxing, entering, turning, moving off the line of attack, and taking the attacker's center. He is a Nidan (second degree black belt) and Fukushidoin (certified instructor) through the United States Aikido Federation.

I was curious and took a class. I think that Aikido is very good for everyone looking to keep fit/work out. This class has fantastic and experienced teachers. The energy of the group is wonderful. I highly recommend that you give Aikido a try.

Both Shihan (6th dan) and Shihan (6th dan) used to visit when I still was a kyu and after 20 years I still enjoy exploring unique aikido ideas here with great dan and new kyu.

AWESOME PLACE TO TRAIN!!! I have been with John and Stefan for, I am guessing, 5 years now. And I cannot think of training anywhere else! If you have an interest in Aikido, or you just want to try it out. And your like close to the New Castle, Delaware Area (Or even if you do not live close but can still make it to class!) you will NOT be disappointed! Also, most of the students there have been with them longer than me. So that says something. And those students are VERY good!!
