No message left. Redialed and it is, in fact, the Kaiser South Sac and Elk Grove Medical Center.  I am a Kaiser member but have never used the South facilities nor do I have any appointments or presdcriptions pending, so I'm not sure why they called and hung up.

Kaiser South Sac or Wyndam calling to schedule specialty appts and it can also be the pharmacy calling to remind you of a prescription ready to be picked up.
