Medical expense relief

Hi my name is andrew Coar, I'm raising money for my dad to help ease his medical expenses due to his insurance company kicking him off of their plan after a major surgery. My dad had surgery on his arteries to save him from having a major stroke. After that surgery his insurance dropped him. He just recovered from that and then had a ulcer which ruptured putting him back in the hospital with no insurance and near death. I just dont want him to recover just to be completely overwhelmed with medical debt every little bit will help relieve alittle stress and will be greatly appreciated.
