Please Help Declan with Medical Expenses

I met Declan after a training in which I shared the story of my brother in laws battle with cancer. He introduced himself and said the story really struck a chord with him as at the young age of 25 he’d been cancer free for 2 years. He lost his previous job due to time off to get treated. He actually battled 2 types of cancer and won! Our conversation shifted to how excited he was to be in the insurance business and more specifically to be with FFL, as it’s a fresh start for him and his new wife. I was saddened to get a call from another friend telling me know that Declan’s cancer had returned and he’d need a stem cell transplant along with Chemo and radiation. His health insurance company is now denying him the coverage for the treatment so after he wins this battle he’ll be stuck with a monumental bill. Please help out what you can. Declan is a great guy and an absolute warrior! Thank you!
