Yoga Teacher Training FAQs

This advanced yoga teacher training is designed for those who want to continue their study of yoga beyond the 200-hour foundation.


 Graduating from this 300-hour yoga certification program allows you to register as a Yoga Alliance RYT-500, which is recognized worldwide. 


While this yoga teacher training program is designed for in-person learning in Worcester, MA, and we encourage this as much as possible, we understand that flexibility matters. We offer hybrid flexibility to join remotely when needed.  We do highly recommend attending in person when possible, as the community and hands-on learning are central to the experience. Feel free to reach out if you have specific questions.
