Rethink Mental Illness Chief Executive Mark Winstanley to retire after more than 40 years with the charity

After more than four decades at Rethink Mental Illness, Mark Winstanley has announced he will retire from the charity at the end of March 2027.

Mark joined the organisation in 1984 and has dedicated more than 40 years to improving quality of life for people severely affected by mental illness.

Having held a number of roles across the charity throughout his career, he’s served as Chief Executive for the past 13 years.

“This has not been an easy decision," Mark said, sharing his decision with colleagues. "Rethink has been a hugely important part of both my life and my career. What I thought would be a job became a vocation, and more than 40 years later I remain as passionate about our purpose as ever.

"The difference the right support can make to someone’s life has always been the reason for this work. That remains as true today as it was when I first started.

“I’ve been privileged to work alongside extraordinary colleagues, volunteers, trustees, campaigners, supporters and people with lived experience who have inspired me every day. Together, we have amplified voices that too often go unheard, strengthened services, and campaigned to drive change across mental health support and policy.

“Leading Rethink has been one of the greatest privileges of my life. But living with long-term health conditions has made me increasingly aware of the importance of giving more attention to my own health and wellbeing. After a great deal of reflection, I believe now is the right time to step back and begin the next chapter.

“I’m confident Rethink has a bright future ahead. We have strong foundations, talented people and an unwavering commitment to improving the lives of people severely affected by mental illness.”

Mark will remain Chief Executive until March 2027 and remains fully committed to his role and delivering the charity’s strategy over the months ahead.

The Board of Trustees has already begun the process of recruiting his successor and expects to provide a further update soon.

Kathryn Tyson, Chair of Trustees, said: “Mark’s contribution to Rethink Mental Illness and to the wider mental health sector has been extraordinary. Four decades of service to one organisation is a remarkable achievement, and his leadership, compassion and commitment have helped shape Rethink into the organisation it is today.

"We’re deeply grateful for the contribution he has made to the charity and the wider sector, and look forward to celebrating his many achievements in the months ahead.”
