Johnson has worked for WCVB since its launch in 1972. He is also a senior medical contributor to ABC News, providing on-air commentary on medical problems for “World News,” “Nightline,” “20/20″ and “Good Morning America.”
“I never felt like a television personality,” Johnson said in a statement. “I always felt like a physician who was talking to his patients. I thought of what we were doing as trying to teach.”
Johnson, who has received many awards during his tenure at WCVB, will retire at the end of the year.
“I must say that the friendships and the support I’ve had from my colleagues in both medicine and media have been so meaningful to me,” he said. “I really cherish those friendships and they’re as important to me as any visible achievement I’ve ever had.”
