Help For Elderly Father With Memory Issues

My father is in his mid seventies and was recently diagnosed with moderate dementia. He lives alone, and is on waiting lists for assisted living facilities. He does alright, but I would like to make sure he has someone checking on him and helping with life's daily activities. I visit very frequently, so this would help supplement my time visiting. Tasks include daily wellness check-in (Did he eat/shower yet? Confused about anything?), store trips, companionship, and very light cleaning. I manage all appointments, doctors, meds, and finances. He is a former fly fishing guide, hiker, and bowhunter, so if you like to talk about the outdoors, he'll have plenty to say!
