Seeking Part-time Senior Companionship In Westminster (Church Ranch Road)

I'm seeking someone who has experience with/is comfortable with people with dementia. Medical experience isn't strictly necessary if you have been a caregiver or assisted your own senior family members. My 77-year-old mom lives in a memory care facility where her medical and personal care needs are managed. I visit at least 3 times a week but would like someone to spend a few hours with her on the days I can't be there (weekday afternoons would be best.) She is friendly and enjoys chatting, walks around the building with her walker or even sitting outside if the weather is nice. Duties include companionship and social interaction but no medical needs Ideally I'd like to find someone open to the possibility of more hours (mutually agreed upon as needed) if things work out when I have to travel for work or other family obligations.
