David is 9 years old and is going into weblos in cub scouts this coming year. He just finished third grade and loves to swim. He is always positive and motivates those around him. He is an only child and is cared for my his single mom Mischell. 
David started experiencing headaches that led his mom to take him to the eye doctor for a check up. Upon examination the eye doctor told them they needed an MRI. One was able to be ran and David was sent emergency to All Childrens hospital  where they were told he has a large mass in his brain. After a six hour surgery, it was determined he has cancer. A biopsy was sent off to decide on a treatment option. 
Financially, this family needs help in every aspect from gas cards, to meal cards, to money to be able to provide the treatments that could save his life.
