In memory of Dr Thomas Lynch

It is with great sadness and a heavy heart that we share the news of the passing of our partner, friend, and colleague, Dr Thomas Lynch, following a short illness. Tom passed away on November 5th, at his home in France.

Tom leaves behind an extraordinary legacy that has profoundly shaped our field and the lives of countless individuals. As a community, we have spent years learning and practicing ‘his’ RO DBT. While we mourn this immense loss, we also carry a profound sense of gratitude. The greatest tribute we can pay to Tom is to continue the vital work he started, upholding the high standards of care he taught and keeping his vision alive in our daily practice.

We will miss his vibrant personality, rigorous intellect, deep compassion, his sense of humour, his kindness and his amazing clinical expertise and we will continue to work together to keep Tom’s work alive and contribute to the benefit of those in our society who are suffering.

We have set up a memorial board if you would like to post a message: https://www.kudoboard.com/boards/1m8rTA3u

We will also be hosting a public memorial in Tom’s memory via Zoom on December 8th 2026 at 10 AM US Central Time / 5 PM Central European Time: Join the Zoom memorial

On behalf of Erica, Jodi and Roelie, with great sadness.
