I had been taking yoga for about six months. After my first class with Perri Institute teacher Callie Ritter, I figured out I was lacking in my foundations. Her yoga class builds you from the ground up and she makes sure that students understand and develop strong background knowledge of yoga principles. Her classes are the perfect combination of physical and mental challenge, as well as relaxation. This allows me to do a sort of mental retooling, enabling me to focus better, while at the same time being relaxed - something that six months ago, I never thought could be possible.
