Denis is amazing! I met him as a teacher in brain injury matters and keep contact with him regularly. He instructs my 1 to 1 classes via zoom, and as he was my teacher at brain injury matters, you may have worked out I have a brain injury. The left side of my body is much weaker and in some ways quite dysfunctional. Denis allows for me to work with my body comfortably while still encouraging me to push myself. I feel his approach to yoga has really helped me strive on with my abilities which I want to do. Definitely top marks from me. If you want to try yoga at any level he is a superb teacher. He definitely gets top marks from me!
