Companion Care Needed For My Father In Portland

Looking for a very compassionate, patient, experienced caregiver for my father, who is 90 years old. Primarily working on Saturday and Sunday, but would potentially need back up on week days. His primary need is companionship; someone to talk to and engage with. He is relatively independent in his self care skills, but needs some reminders regarding his daily routines. Occasional transportation to the nearby grocery store.
