Michelle Tibbs, Yoga and Pilates Instructor

Michelle began practicing yoga in 2002 after the birth of her third baby boy. Having experienced a hip misalignment due to labor and delivery, she found that practicing yoga not only healed and balanced her body by realigning it, but that it also calmed her mind, energized her body and restored her to wholeness. After taking her first yoga class in 2002, Michelle sought to share her love for yoga by teaching in the inner city of Seattle. In 2005, she completed her 200 hour teacher training with YogaFit and has been teaching ever since. In 2007, she completed her mat Pilates teacher training. 

Michelle is grateful and honored to be able to share her love for Pilates, wholeness and wellness!  She hopes to help her students feel the same wholeness and balance that she is grateful for every day.

Jen Hughes, Yoga Instructor

Jen attended her first yoga class with her mom at age 16 in Maine. She has been practicing yoga since 2000 and teaching since 2011. While attending school in Colorado for experiential education and recreation, she studied Iyengar yoga and Ashtanga yoga. Her desire to teach and share yoga with the world was sparked in November 2007 after losing one of her teachers unexpectedly to suicide. “The only way I could process how I felt was on my yoga mat and I knew that my dharma included offering solace of this kind to the world. Yoga is so much more than downward dog and balancing on one leg, it’s about building capacity for our lives.”

Jen's classes mirror her personal practice: getting totally in tune with what your physical, emotional and mental bodies need, allowing your edge and intuition to meet at a beautiful place. Jen has had the opportunity while living in Seattle to deepen her practice through completing the 8 Limbs Yoga Teacher Training program and attending workshops with Nicolai Bachman and Rod Stryker. In addition to teaching yoga classes, Jen loves making people laugh, visiting her family in Maine and sipping tea while watching birds on her deck.

Eunice Hobbs, Yoga Instructor

Eunice was drawn to yoga because she found she could be herself while practicing. When Eunice first began practicing yoga, however, she felt intimidated by the thin, experienced people she saw in classes. She kept practicing, though, because moving through the postures made her feel great! Being in the poses facilitated a shift in her awareness that helped her accept and love her body. 

Now Eunice enjoys offering the gift of self-acceptance to her students. As a medical assistant for 19 years, part of her inspiration to become a teacher was to motivate others to get on their mats and realize that yoga applies to regular life. Eunice believes that everyone--young, old, curvy, slight, black, white, and everyone in between--benefits from a regular yoga practice. As a yoga instructor, she ensures that her students feel safe to explore their body, mind and spirit while on their mats. 

Eunice trained at Urban Yoga Spa and received her 200-hour RYT in 2014. She began community yoga classes at Odessa Brown and still teaches there regularly. Eunice is a mother of three young adults.
