Hello Dawn, this may be a place to start. Your father must have attended an officers candidate school somewhere.
It appears there is no Association for the 57th Signal Bn. but i did come up with a link for the SIGNAL CORPS OFFICER CANDIDATE SCHOOL ASSOCIATION
On the Homepage, click the "WWII Era" button in the upper left corner. On the page that opens, there is an email contact for a Major Richard Green. You can send him the info on your father, hopefuly they can be of some assistance to you.
