Throughout his career, Sutton has trained nearly 300-400 dogs, but more importantly, he has made many lives better.
"I have a student who I've trained a couple times - huge, huge New York Yankees fan, and she wanted to learn how to get from her home in Morris Plains, New Jersey by herself with her seeing eye dog...it's a madhouse, and the dog fights through that. It's amazing," said Sutton.
Being underground makes Sutton think, "What if I couldn't see.... would I have the confidence and the daring to do that?"
When all the people go hurrying along - head down or looking straight ahead Walt Sutton has found a way to see something wondrous.
