When working with couples my teachers have been Sophie Slade of Imago Relationship Therapy, Hedy Schleifer and Sue Wintgens
Where appropriate I use some of the newer methods available derived from Energy Psychotherapy (for example EFT "tapping") which can be helpful in releasing trauma.
With Covid-19 all my work is on-line for now. I am happy to work in this way and overcome the inevitable limitations.
