I have been meditating for some 35-40 years and studied both in the Vedic and Buddhist traditions as well as Christianity.

In my professional life I was a Primary teacher. I have 4 grown up children and am now retired from full-time teaching of children.

I took up mindfulness  teaching around 5 years ago. I have taken the 8 week MBSR course myself and then went on to complete the week intensive level 1 teaching course at Bangor University. I continue to practise meditation and attend retreats regularly.
