Meet the TLI Team

The TLI team is a close-knit group of seven people with wide experience of ministry in parish, diocesan and national settings. Our daily work enables us to keep in close conact with the changing landscapes of leadership in the Church of England and these experiences inform our programmes.

We also draw upon the expertise and experience of a wide range of visiting speakers and consultants in the development and delivery of our programmes and publications.
