San Antonio Regional Hospital is three miles from much of Ontario and Upland. We are not on that campus. We are the residential next step when a physician says the person does not need another night in a hospital bed but also should not go home alone.
Claremont and Montclair families use the same 10 corridor. If you are coming from the Claremont Colleges area, say so — we will pad the drive time.
Foothill Boulevard is not a shortcut at 5 p.m. Use the freeway unless admissions tells you otherwise.

- Are you affiliated with San Antonio Regional?
- No. We are an independent DHCS-licensed residential program. Hospital social workers may still call us as a community resource.

- If they are medically appropriate for residential support and a bed is open, yes. Bring discharge papers if you have them.
