Kari Baigrie

Instructor: Prenatal & Postnatal Yoga

Born and raised in Cape Town South Africa, Kari turned to yoga in 2001 to heal a knee injury. With a background in dance she was drawn to the vigorous, flowing movements of Vinyasa, but kept coming back for the transformative, inner journey that yoga took her on. As a teacher, Kari draws from Vinyasa but also Hatha and Yin Yoga for the balance that they bring to a practice. Through her prenatal and postnatal training, she loves to pass on to new moms the gift of support that yoga was to her, during her own path to motherhood. Karen’s classes are flowing and soulful, with room to be as strong or gentle as you may need to be. She is passionate about yoga being for all bodies and finding ways for everyone to enjoy the benefits of this ancient source of healing and wholeness.

Karen trained with Nubia Teixeira’s Bhakti Nova school of Yoga and lives in Marin County, where she grows vegetables, hikes, teaches yoga, makes art and is mom to two middle school sons.


Raquel Benson

Instructor: Teen Yoga

Raquel discovered yoga as a teen over 10 years ago in Salt Lake City, Utah. A physical therapist suggested taking classes to regain range-of-motion after an elbow dislocation in gymnastics. She quickly saw the benefits yoga contributed to her healing process and returned to full strength within just a few months. It was the acrobatic arm balances and inversions that motivated her to further develop a yoga practice and eventually begin teaching to share her passion with others. Raquel leads a vigorous vinyasa flow incorporating balances, inversions, and deep stretches moving to the beat of her playlist. Yoga helps her feel stronger, healthier, and all around happier which she promotes in her teachings.
