Are You Interested in the Benefits of Yoga?
The practice of yoga invites you to breathe deeply, relax into the present moment, and feel what’s happening inside and around you.
Dynamic Gentle Yoga Class
Offered in-studio or on Zoom
Breathe, relax, and feel during a practice of slow, mindful, internally-focused movement.
Discover new strength and flexibility while honoring your limits, strengthen your concentration/focus, and relax your nervous system in a non-competitive environment.
Private Yoga Sessions
Offered on Zoom or in-person
Want to practice one-on-one? Let’s work together to customize a practice to meet your needs and preferences.
Private yoga sessions can be done in a chair or on a yoga mat – or a combination of both to focus on what you need, such as stretching, pain relief, breath, and stress-reduction.
I’m available on Zoom or if you would like to meet in-person, I am located in Frederick County, Maryland.
