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.

Jacki Libby


Jacki Libby

Jacki found yoga as a safe place to hide from the chaos of everyday life. She immediately became inspired by the healing powers of yoga and began calling it ‘magic.’ A teacher of hers told her that may be false advertisement, but for Jacki, yoga has been just that – magical.

Jacki teaches Vinyasa flow – a vigorous, athletic, breathing practice that builds heat within the body, strengthens and conditions the body and also increases flexibility. She also teaches gentle restorative – a very slow moving, meditative, breathing practice that uses props and the weight of the body to relax and settle down. She believes we spend most of our days gripping, holding, clenching, and hardening. We take very little time to let go, release, and to be soft. This is the reason she loves the opposite yet complimentary energies in Vinyasa style and Restorative style yoga.

Jacki steps on her mat everyday – as a student and a teacher. Her work integrates movement with mindfulness. She offers clear instruction, with an emphasis on how the pose should feel rather than how it looks. Her intention is to build trust – a connection with her students, and to create a space where the students can begin to trust themselves. Because that’s where all the magic begins.

Jacki received her Yoga training at Metrowest Yoga and Training Center in Worcester, MA.
