It has been a long time since my son, Robert Graves attended the Illinois School for the Deaf. I believe he graduated in 1992 or 1993. It was a learning experience for both Robert and myself. I would rate the school and dedicated teachers A-1. I would like to know if it is possible to get a copy of Roberts diploma. Somehow throughout the years, his diploma got lost. Would very much appreciate it. Thank you! Pat Schwengels........Roberts mother.
