Way back in 2000, Mark Williams opened doors for her to start bringing mindfulness to the patients of a Welsh oncology department where Trish herself had just finished treatment. Over the 20 years that followed, she continued to teach enabling the programme to slowly adapt from the original MBCT, with John Teasdale guiding Trish as they teased out what was needed for this particular group. From this, a workbook for teachers was published (Bartley, 2012) followed by a book for people with cancer themselves (Bartley, 2017). Trish has continued to work with people with cancer, including training many teachers in the programme in the UK and further afield, and offering online one to one connections to a few people at the end of their lives.
