Alan's Marshall sr. Medical bills

This is for my dad Alan Marshall he was diagnosed with colon caner in June 2016,  Because of this he has been in and out of the hospital and has some bills that he is unable to pay. He has had first round of chemo and radiaion, and his first surgery went well.  He has recently started his second round of chemo and will have the next surgery once done with this round.  He grew up in the lakeside neighborhood and worked at Marshall Hardware as a kid.  From 2000-2010 he ran the Lakewood one stop along with his Wife Linda, kids Jenny, A.J. and Kristy.  He currently has been working at Marshall Hardware.  He was also a volunteer fire fighter with Normanna fire department for about 20 years.  He is also an avid hunter.  Loves to bird and deer hunt.  Any help would be greatly appreaciated.
