Who do I contact to send money for some expenses for a sober living resident

You need to contact them for the right answer. Let them know what you are looking to do. They will have the best answer.

I spoke to a woman at the information department and she said they couldn't receive packages but she said I could mail books. Maybe I misunderstood. I'll check again

There are no expenses up there, and they won’t let you send the clients money. Or candy, or stationary, or really anything at all except a letter. The only expense I can think of is a suit for graduation from the program which they purchased at the on-site thrift store usually for about $5.00. If the client doesn’t have $5.00 he still gets the suit...👍🏼
