UPDATED with a reply to "Holly N.":
I did contact the corporate office. They assured me that the director would be spoken to about these incidents. I also contacted the AZ State Health Department who not only planned on contacting and educating the director and staff, but also informed me that a Sunrise Preschool in Tucson (among others) had been closed down due to health code violations.
There is NO WAY I would have continued to allow my children to be subjected to such negligence in order for them to try to "rectify the situation". I stand by my review and will warn any parent who is considering Sunrise Preschool, or ANY child care facility, to do your homework and call the DHS in your area.
