Our classes are limited to 12 people per class time.
We ask that you reserve your space in class through our Zen Planner Scheduling Software.

In order to reserve class space you will need a Zen Planner member login account. This is different from the website member login. Your Zen Planner Login is emailed to you when your membership is created.
