St. Mary's is Kaiser's hospital proxy. You are able to go to any ER and if needed, Kaiser will have you transported via ambulance, to either Kaiser Ontario or Kaiser Fontana. This happened to me and it was painless. I prefer Kaiser Ontario. Kaiser Victorville has an Urgent Care and they are building another Care center in Hesperia, California.
Kiaser Fontana. Sierra exit off Interstate 15, about a 35 minute drive feom Vicrorville on a goos traffic day.
