Help Ruben Galvan with Cancer Treatment Costs

This is my friend Ruben Galvan. He works hard as a custodian at Wylie High School and always puts a smile on the students' and staff's faces. He has stage 4 cancer. He is scheduled to go to Houston for four weeks in June. During that month, he will be treated three times per week. Please help lighten his load by helping with expenses. If we can raise $4,000, he won't be burdened with worrying about out-of-pocket expenses (hotel, food, gas).
