It's a tough question. I think most people don't know where to meet someone. Church meetings sound like a good place to me if she is religious, where she can find like-minded people. Meet-up groups is another option if she is interested in something in particular, I guess. I wouldn't show my worry to her and push her in this though. This might make things worse for her. I think it's her responsibility to take the actions. You can guide her if she asks. She sounds like a person who can take care of herself. I understand your worries, though.
