The instructors at Yoga Tree are very well trained and are dedicated to their practice. They are friendly and helpful and welcome to working with people at all levels. I've always felt safe and included in all of the classes I've been to at Yoga Tree. They have classes for various levels including lots of speciality workshops sprinkled through out the year. It's a good idea to check out their website often to see what's happening. The only downside is that some people may consider it a bit expensive at around $12 or so a class, but you certainly get what you pay for.
