Mark Stephens is an extremely knowledgeable and compassionate teacher. I chose his teacher training because of his philosophy of sustainability and his focus on sthira sukam asanam (steadiness, ease, presence of mind). The amount of knowledge of yoga anatomy, history, asana alignment and sequencing that I gained through the training was astounding.  I left speaking a new language, living a new culture. Once I completed my certification, I was hired by a local yoga studio just one month later. During my practice teaching "interview," the studio owner was clearly impressed with my knowledge of anatomy, alignment and sequencing - all of which I attribute to Mark's teacher training.
