Companion Care Needed - Full-time / Part-time

About who needs care: My wife is in her 60s with Alzheimer's. She's so loving and caring but we need some assistance during the day so I can work. Would love to have someone who has experience with Alzheimer's, keeping them active. She really needs a kind person who can do little activities outside of the home with her. She loves getting a coffee and chatting and being in a community with other people. She sometimes needs someone to just take charge and not ask her if she wants to do something but just take her along for a walk, errand, to a senior center, etc.
