David Perry's brain tumor medical bills

On the night of the 30th, our dad suddenly started convulsing in his bed and was unresponsive. By the time the ambulance took him to the emergency room he had suffered 3 seizures, each lasting about 5 minutes, and had yet to wake up. After an MRI showed a mass in his frontal lobe, the neurologist determined it a tumor. Fortunately, he has no paralysis or brain damage, and was fairly lucid this morning when he regained consciousness. To our relief, he is acting like the same dad we know and love (despite having been heavily sedated). The tumor will need to be removed, of course, at a time yet to be determined.
What he needs help with is the financial burden. This has been, in his words, the hardest year of his life, as he took a risk in becoming self-employed and leaving his prior job, and suffered setback after setback. Through his and his loving wife's hard work and sacrifices, they have been able to keep their house. But obviously, this medical development is both untimely and devastating, made worse by the fact that he has no health insurance coverage. Anyone who knows our dad knows he isn't one to ask for help, but we also know there is no way he can pay the looming medical expenses on his own. If you are able to contribute any amount, no matter how small, we will all be incredibly grateful!
