Gary has been practising mindfulness and meditation for over 35 years. For the last thirty years he has been teaching meditation and Buddhism at the Manchester Buddhist Centre and the Dharmavastu Study Retreat Centre in Wales (now sadly defunct), and as a visiting teacher at Buddhist Centres in the UK, Ireland, Sweden, Germany, and America. He is also the author (under his Buddhist name, Ratnaguna) of The Art of Reflection.

He began working with Vidyamala and Sona in 2003, wanting to work outside of a Buddhist context, helping people who are suffering, but using his skills as a teacher. As well as teaching on local Breathworks courses, he trains health professionals and others in mindfulness as a health intervention.

He is the Director of Training for Breathworks, and has developed the Mindfulness for Stress course, which he delivers regularly in Manchester.
