MIDDLEBURY — Bob Gold has divided his life into two parts. He spent the first part as a dentist. He studied at the New York University School of Dentistry and was a clinical assistant in prosthetic dentistry at Harvard University. Gold ran a successful private practice for over 20 years in Manchester, N.H.
Then in 1996, while he was sitting at an intersection, a pickup truck crashed into the rear end of his car, leaving him with traumatic brain and spine injuries. He lost his ability to read and write, and all ability to practice his profession.
