Please forgive the gushing tone of this review. I can't help it! I'm just back from a yoga retreat in Hawaii. This is the Hawaiian retreat with Ken. He has an uncanny ability to meet an individual and a group right where s/he/they are and to stick with that focus. I think of him as a healer, a leader, and an inspiration. Last year, I was a yoga novice, yet through his gentle leadership I kept up well. And that experience was repeated this year. As others have written, Ken also excels at integrating the spiritual foundations of yoga with the physical experience of the practice. Wish I lived in the Bay area, instead of the other side of the country!
