This is a little less complicated than we originally thought. Apparently letters are the only mail he can receive directly from us. Unfortunately, he is not allowed to receive stamps or pre-stamped items either. All postage has to be purchased through the commissary.
Use the following format when writing to Steve:
STEVEN MARSHALL WILLIAMS 53327-074
FEDERAL MEDICAL CENTER
P.O. BOX 14500
LEXINGTON, KY 40512
Please do remember Steve when sending out holiday cards. They will do a lot to help his spirits and will hopefully help feel connected to us on the outside.
