Companion Care Needed

About who needs care: She has middle-late stage dementia. She needs help doing everything, and my father is almost 80. We live on the property with them, so there's lots of support. But, none of us are trained in dementia care. She's on hospice care, so they take care of bathing her. We currently also have a home care agency assisting 4 hours, 3 days a week, which allows for some flexibility with times. Services needed include: feeding, bathing / dressing, going to the restroom, and mobility assistance. Additional Info: Must be at least a CNA.
