Helping my coworker with medical bills

My coworker Kara found out a few months back that her husband Albert has Leukemia.  Thankfully he is in remission now, and he has undergone a stem-cell transplant.  While he will hopefully make a full recovery, Kara and Albert are having to deal with some mounting medical costs, and this is my attempt to help the two of them focus more on Albert's care and and less on the financial burden.  I appreciate anything you can voluntarily contribute to help them get through this situation, and even $1 goes a long way!
