Jewish Care is hoping to raise £150,000 from its Rosh Hashanah appeal, which focuses on the care and support shown to its residents.
The featured character is Sharon Arad, social-care coordinator at Clore Manor in Hendon. In a letter to donors, Jewish Care chief executive Simon Morris highlights the lengths Mrs Arad and her colleagues go to help clients and their relatives - from "picking up flowers to welcome a new resident to helping to organise a shivah.
"People like Sharon don't want thanks for the immense amount they do. But their work only gets harder as residents get frailer and the care they require increases."
Mr Morris added that over 70 per cent of his charity's residents are funded by their local authority. "But this level of funding falls far short of the cost of care we provide."
