Help Tristan with finances while in Nashville

Hi my name is Angie. I’m asking for help for my nephew Tristan. Tristan is 26 years old and in heart failure. He currently is not a candidate for a heart transplant but he will be having LVAD surgery within the coming days. After surgery he will be in the hospital for about 6 weeks then he will be required to live close to Vanderbilt Hospital with 24/7 care. The hospitality house will cost $400 a week. Needless to say Tristan has been out of work since his diagnosis last December. His wife is in her last months of RN school while also working 32 hrs/week. They have a 4 year old daughter. Anything donated would go towards housing, food, and travel expenses for his wife.
