“My uncle was smart, funny and worked until he was 60 but his speech and ability to communicate with people was such a frustration for him. He died in his 70’s a couple of years ago having led a fabulously full life and was loved by many but I know his life would have been even more fabulous, and more importantly, he would have had the independence that he craved if The Shepherd Centre has been around for him when he was a child,” says Sandra.
