Lawrence Marshom was so impressed with the care his grandson Noah received at Great Ormond Street Hospital that just saying thank you didn’t seem enough.
The 65-year-old former stockbroker decided he would sign up as a volunteer and was approved after two months of intensive training.
“It was a dream come true for me. I was like a kid,” he said.
Three years on, he has produced a book of poems and songs about his exprience to raise money for the hospital’s charity.
