Help Larry with his finances after his surgeries

Hello we are Larry's parents in San Diego. Larry is 32 years old. He recently just had heart surgery. He is recovering amazingly well! He is strong and in good spirits and we are very proud of him. After he recovers from heart surgery he will be scheudled for a kidney transplant. Larry does have insurance and he does have some savings. But as we all know being out of work for so many months will deplete his savings and not everything is covered. We would like to ask friends and family for as much help as possible and help him with his financial recovery. Thank you so much for your help!
