Normally we would discourage you from board & train, but your circumstances are special and if you can find an honorable one that comes with great references then it might be best. Just besure you are clear on their methods and in agreement with them. They should ask you to take some lessons from them to ensure that you are clear on the methods and can keep it up.
Good luck with your dad.
