Training with the Central PA and Eastern Shore MD group
Ben is both highly experienced in the material and great to train with, get in touch with him if you are going to be in the area and are interested in meeting up to train.
Sangenkai Germany has study groups in Darmstadt and Manheim.
Kristoffer and Matei are first class martial artists and great people to boot; if you're in the vicinity of Oslo I can't recommend enough getting in touch with them to train.
The Spanish group are a great group to train with and you'll find a number of dedicated practitioners from several martial arts who are putting in serious work on the material; they're also lovely people who enjoy good fun, food and drinks outside of training.
Mika had been training in Sangenkai methods for many years and can be relied upon for great training, get in touch if you're planning on being in Sweden anytime.
