Susan Britton, RN - Psychotherapist - Yoga teacher

Susan Britton worked at The Griffith Edwards as a replacement therapist from 2000-2002. She previously had a long nursing career in Palliative Care at the Royal Victoria Hospital. When she had some time to orientate herself to this new work, she realized that there were many overlapping issues (ie. grief, loss, and family dynamics). In 2003 she decided to become a yoga teacher and after a 200 hour intensive training and being aware of the positive aspects of yoga and recovery, she applied to teach yoga to the clients of the Day Program. The techniques she uses are warm-ups, postures, relaxation, breathing techniques and meditation. After stopping the use of a substance, one becomes aware of their emotions, their bodies and their busy minds. This is where she believes that yoga can be very beneficial in giving the clients some tools to replace their substance use and to be able to sooth their nervous system.

Since 2003, she has added 300 more hours of yoga teacher training and will continue to keep pursuing more education.
