I work for a disabled physician who is looking for ways to communicate with other disabled physicians or retired doctors. Can you suggest anything for him?

You should try the American Society of Handicapped Physicians. It has no Web site that I could find. But the director is William Lambert, and the society’s address is 3424 South Culpepper Court, Springfield, MO., 65804. 

Canadian Association for Physicians with Disabilities

The Association of Disabled Professionals

These groups should be able to help your boss get in touch with others who share his concerns.
