Alzheimer’s Society has appointed Michelle Dyson CB as its new CEO

Michelle Dyson, our new CEO

Michelle is the former Director General, Adult Social Care at the Department of Health and Social Care and joined Alzheimer’s Society on 1 November 2025. Michelle, who recently left the Civil Service after almost 27 years, was awarded a CB (Companion of the Order of the Bath) for services to health and social care in the New Year's Honours List 2025.

Michelle Dyson said: “I am thrilled to be joining Alzheimer's Society as Chief Executive Officer. I am so impressed by the scale of what Alzheimer's Society does - in terms of its direct support services, hugely ambitious programmes of research and innovation and wide-ranging partnerships across the UK. 

"The challenge of dementia is enormous, a cruel disease which is already the leading cause of death in the UK. Three of my grandparents had dementia so I have personal experience of the terrible human consequences. 

The sense of ambition and possibility at Alzheimer's Society is striking, and I am honoured to lead the charity at this important time.

What our Chair of Trustees thinks

Dame Suzi Leather, Chair of Alzheimer’s Society, said: "I am absolutely delighted to announce Michelle Dyson’s appointment as our new Chief Executive Officer. Among a highly competitive and talented field of applicants, Michelle emerged as the outstanding candidate. 

"A hugely bright dedicated public servant, Michelle has wide experience of different policy fields in central government and has led in some tough areas of public policy. Her unwavering commitment to driving positive change and making a difference to people’s lives shines through her professional career. I know she will bring a passion for the dementia cause and a determination that in all that we do, Alzheimer’s Society excels. 

The entire organisation, board, staff and volunteers, welcomes Michelle and looks forward, under her leadership, to increasing our impact as the leading charity working to ensure that dementia no longer devastates lives.

Michelle has taken over from Corinne Mills, Chief Operating Officer at Alzheimer's Society, who was interim CEO since Kate Lee left the organisation earlier this year.
