Ed Poole (Dad) Medical Expenses

I am hopeful we can help my dad and mom out. In December my dad found out he has cancer, Stage 4 small cell lung cancer. He has always worked so hard to make a living and always gave his all to help a friend.
Dad retired and was driving a school bus trying to live on a fixed income.
Now with all the cemo and cancer treatments, him and mom won't and don't have enough to cover the cost.
I asking for help because he is a proud man and would never do so.
I just don't want him and mom to have to worry and focus on getting better and kicking cancers but
Thank You
His Family
