Our Board

Adam joined the Cornerstone Board in 2023 having spent over twenty years in management and leadership roles in health and social care commissioning.

Adam’s training and professional background include a practical interest in the ‘Social Determinants’ of physical and mental health, which includes the link between decent, affordable housing and people’s overall well-being and life opportunities.
