Companion Care Needed For My Wife In Santa Barbara

I need a companion care provider with Alzheimer's / Dementia experience for my wife in her 60s. Schedule Details: The position would start part-time and gradually increase over time. So a few hours once or twice a week initially. My wife is a very young 62 and is cognitively very sharp but she suffers from Primary Progressive Aphasia so has lost almost all her ability to speak, or understand others. She is still very independent but has trouble with anything computer or phone related, plus she has lost her driving license so needs help getting to places. Preferences for a caregiver who is a non-smoker and comfortable with pets.
