No, but they are only there on specific days of the week. Call them and find out what they are. (Leave a message if you call when they're not there). I think Wednesday is one of the days they are there...and maybe Saturday (not sure). They are a great organization....do great work!
You don't need an appointment but check their website for hours and days. They are terrific and great to work with. I highly recommend them.
