I'm a graduate student at Stanford and caring for my dad. I'm looking for someone to take care of my dad for a few hours 1-3 times per week (while I'm at work), taking him to hiking trails and tutoring him basic math books at a cafe or library to help with stimulating his mind and memory. I am covering his physical exercise at the gym every day but I am looking for someone to keep him mentally stimulated during the times where I have to work. Thanks!
