A specialist team providing
specialist care
We provide specialist care for vulnerable people who present with challenging behaviours associated with complex neurodegenerative and mental health needs.
Residents who live in our homes primarily have a neurological degenerative condition such as Dementia with an underlying mental health condition which makes them inappropriate candidates for dementia care homes or residential care homes for the elderly.
“At Cornerstone, we see things differently;
we do things differently.”

We do more than the expected
We’re unique
Our approach and attitude towards specialist care have received industry recognition, but our residents always remain at the core of our service, underpinning everything we do.
Our multidisciplinary team are specialists in their field and we only recruit individuals whose values align with our own. This is why every member of our team, from ancillary workers to nurses, are dedicated to working with dignity, honesty and respect. They come to work every day to be the best they can be, with belief in their abilities to provide specialist care.
