A Sioux Falls man who created an organization to help those battling cancer has died. 

Matt Ellefson formed SURVIVEiT after doctors diagnosed him with late-stage lung cancer in 2009. 

SURVIVEiT allows cancer patients to give feedback on the care they’ve received and lists cancer centers as rated by survivors. 

It also features a resource library put together by doctors and reliable links. 

Here’s a story we previously did with Ellefson.
