My Mother and my step father have lived at Sun Terrace Prosser for two years!!! As a family we are truly grateful for the care provided. My Mother is solely dependent on the staff and they do a fantastic job of being attentive to her needs!!!

My parents were in Sun Terrace for 7 1/2 years. They took good care of them through the covid years and as they each declined in health. The staff really cares and I had peace of mind knowing they were looking out for them when I wasn’t there.
