call the building and ask to talk to the activity director or activity staff. they will help you volunteer and direct you to residents who just need someone to talk to or sit beside
edit: I recommend anyone looking to get into volunteer work do this. (especially if you have anxiety about volunteering or working with people; old folks often can't remember shit abt specifics but they do remember when they get visits.) it is easy work, it'll make you feel good, and you'll get some pretty good stories out of it.
they do not. most activity departments/skilled nursing facilities are desperate for volunteers. staffing ratios in snf are untenable and even in upscale nursing facilities these people are not getting meaningful one-on-one time.
if anyone here is seriously thinking abt doing this and has questions, please hmu.
