Kathleen Snapper

Kathleen Snapper yoga teacher

Kathleen Snapper

Kathleen has been teaching at the Prana Center since 2014.  She often begins class with a few moments of mindfulness meditation and she may offer hands-on assistance in alignment during her class.

She began practicing power yoga with Shawn Shaw in Ashland in 2003.  She had always been active in group fitness classes and martial arts but found a more peaceful energetic feeling practicing yoga postures and making the connection with pranayama. 

When her children left for college, Kathleen decided to spend some time on self-discovery.   Not sure what she should be doing in this next phase of life, she decided to quit her office job and register for a couple of college courses.  She practiced yoga, meditation, and journaling and spent a semester working on a research project and looking at her world through a camera lens taking many great photos.  

During this time of self-discovery, Kathleen began yoga teacher training and received her 200-hour RYT in Vinyasa Flow at H.Y.P. Studios in Needham with Jennifer Houghtaling and Alex Amorosi in 2013.

Kathleen continues to study yoga and meditation and recently completed additional training in Yin Yoga.
