Life for Mark's Medical Fund

My father Mark is in need of a liver transplant. He was diagnosed with a liver disease and cancer serveral years ago. Through surgery and thanks to God, the doctors were able to remove the cancer, however there is a high probability of the cancer coming back.  Unfortunately the liver is incurable.
Doctors in Houston request Mark to have a liver transplant. His health has continued to decline over the years because of his liver disease and has since caused Encephalopathy which is a disease, damage, or malfunction of the brain.
He has to continue to take medication on a daily basis to help prolong his life and to give him as healthy of a life as possible with the help of medication and God. His medical insurance has been cancelled because he has been unable to work needless to say medical bills are piling up and medication is extremely expensive.
Funds are desperately needed to help one of the most kindest, lovable and sweetest husband, father and grandfather ever.  Mark is my step-father whom my mother, sisters and I love dearly. My birth father died at the age of 32 from leukemia when I was just 12. Mark is only 60 and we can't imagine losing another father nor my mom another husband at such a young age.
Please help my family!
