I've learned that the wife of one of my spinning class fellow students is a certified yoga instructor. She's been practicing since 1985 and received her teaching certification via a 3-year residency at the Himalayan Institute of Yoga Science and Philosophy and has also worked at the Center for Holistic Medicine in the Chicago area.

It sounds good, but I don't know anything about Yoga certification. She offers classes through a local area church - several 8-week programs. I just have her winter/spring schedule but assume that she will teach all summer.

What say ye Yoga mavens, is this good certification?
