Al Dewsnap

Yoga Instructor

Yoga Certifications: 200-Hour RYT Common Ground Yoga



Al is a 200-Hour certified yoga teacher and lifelong student of yoga. Al first started
practicing yoga during her time as an undergrad at UMass Amherst, at a time when she was
very overwhelmed by the pressures of her coursework. Each time she got on the mat, she felt
more and more connected to the body and inner world, providing an increasingly solid
foundation to stay grounded through those stressful and challenging times. In 2015, Al took an
8-week Mindfulness-Based Stress Reduction (MBSR) training, which formally introduced her to
the art of meditation and how the practice translates to situations off the mat. Yoga and
mindfulness have since become a cornerstone of her wellbeing, and as her practice deepened,
so did her desire to share it with others. As a yoga teacher, she is inspired by creative and powerful, yet nurturing flow sequences that challenge and inspire students to get to know the strong, resilient warrior within and cultivate empowered habits of self-care. She guides students with the intention to coordinate movement with breath, to bring awareness to our inner world, become more in-tune with the body, and to remain grounded and balanced in the face of challenges both on and off the mat.
