Help my brother fight leukemia!

Today we received some shocking news... after visiting doctors and going to the ER, my brother was recently disagnosed with acute lymphoblastic leukemia. This is a very unexpected and unfortunate situation and I hold back tears as I type this up. He has been an amazing brother, son, friend, and father of 4! He recently had two beautiful baby boys. He already has a lot on his plate being a dad and, as we all know, treatment is not cheap. Any help would be so greatly appreciated. If you cannot donate that is completely understandable; sharing this is just as appreciated and helpful. I’m not sure how much everything will be but I’m trying to help my brother out as much as possible to relieve some of the stress he has already taken on. Thank you all!!
