Aisling-Duffy-CEO-Certitude-Yarrow

Aisling has spent her career to date working within not-for-profit organisations, seeking to improve opportunities for people with learning disabilities and people with mental health support needs.

Raj Mungur – Director, Care and Support

Raj joined Yarrow in 2002 to head the care and support team and in 2015 he was promoted to Director of Care and Support. Raj has worked in both the NHS and the voluntary sector having started his career as a qualified nurse for people with learning disabilities with a keen interest in resettlement work. In the early 80’s Raj took the lead role in moving a group of young people from an institutional setting into an ordinary house in the community and was later part of a larger resettlement project which involved moving 55 people out of a long stay hospital into ordinary living in Guildford. Raj has developed, established and managed community-based services for people with a range of support needs including complex needs. Since the closure of hospitals, he has seen many shifts in approaches from normalisation, social role valorisation to person-centred support and now personalisation, and throughout these changes his guiding principle has been to see people take their rightful place in society and not be marginalised.

Darren is an accredited safeguarding trainer for the organisation as well as leading Yarrow’s behaviour support team in supporting our services to manage people with complex behaviours. Darren’s recent work has been to develop services under an Individual Service Fund, transferring them from an existing block contract into personal budgets allowing people the greater opportunity to choose the services they want.
