Companion Care Needed For My Mother In Chicago

About who needs care: My mother has been diagnosed with modest dementia. She and my father are still married and he's in relatively good health (he's 10 years younger), he takes very good care of her, but could use some professional support, especially because he would like to be able to be volunteer with his church on Thursdays in an activity she is not able to participate in due to her limitations. Looking for someone to come by at least on Thursdays to check on her, help her make lunch, do some basic housekeeping, and possibly some physical therapy for her recent shoulder surgery and/or just take a walk to get some exercise. My father has ADHD, so I need someone who will be proactive in confirming the schedule every week to keep consistent care. Services needed include: meal preparation, errands / shopping, and light housekeeping.
