Go onto Meetup.com and see if there are any relevant meetups in the San Francisco area for people looking to practice English. Alternatively, just go to any Meetup for a topic she's interested in (e.g. crafts, health, etc.) and she can talk and interact with the people there.

I would recommend that she volunteer somewhere (a non-profit or a clinic) where she'd be talking to people for most of the day. The best way to improve is just by practicing. I think that'll be more efficient and effective than any of these language sites/products.
