Companion Care Needed - Full-time / Part-time

I need senior care provider with experience with Dementia patients. Our care concerns are: Help Staying Physically Active, Companionship, Errands / Shopping. Looking for a companion that can take her out of the house a couple of days a week while we are working. The social aspect is what we need help with. Maybe going to a senior center or lunch or taking an art or gardening class. We might ask you to run errands occasionally. We need her to have a "friend" to do things with. She is a DNR. She still knows who we are but can get agitated at times. You will need to be able to manage that if it occurs.
