Helper/assistant

I am looking for an assistant to my father who is starting to struggle with his memory. He is very independent, but struggling keeping important tasks organized like scheduling and keeping track of his upcoming appointments, keeping track of doctor recommendations from these appointments, and keeping his medications organized. It would be helpful to have someone check in on these things to help him stay organized and attend the appointments my sister and I are unable to attend due to work. He also could use help prepping a couple meals for the week and getting grocery lists together. He can do the shopping but needs help with the organizing! This would be an as needed, someone more so on call (non-urgently) to be as an assistant to him to keep him organized as he is struggling to stay on task.
