I have been training in Tae Kwon Do for more than 10 years with the last one and a half years with Mariusz Steckiewicz. He is a great instructor with a lot of experience. He tries to attend to the wishes of his students and always considers their experience, physical needs and abilities.
Mariusz gets along very well with people, particularly well with children. He is a patient and motivating instructor. He combines Tae Kwon Do with the necessary fitness and core training, with diversified, well prepared training sessions.
I can definitely recommend Mariusz as an instructor.
