Companion Care Needed For My Father In Scappoose

I need a companion care provider with Alzheimer's / Dementia experience for my 89-year-old father. He has some short term memory loss but is still fairly capable in taking care of himself. We would prefer someone who can handle light housekeeping and maybe help preparing meals as he has a hard time operating his oven due to poor vision. He loves to go shopping so would need a ride as he no longer drives. Preferences for a caregiver who is a non-smoker. He likes his privacy and lives out in the country, so a few hours per day for maybe 2-3 days per week would be awesome!
