DemiCon is hosted by the Des Moines Science Fiction & Fantasy Society.

The Des Moines Science Fiction & Fantasy Society, INC (DMSFFS) is an non-profit charity 501(c)(3) organization located in Des Moines, Iowa. It is entirely volunteer run.

DMSFFS strives to inspire individuals and communities to READ, IMAGINE AND THINK; creating a better world through education and support of literacy, science and the arts.

There are a number opportunities for you to support our vision.

Give financially

Each year we select a charity or cause to raise money for throughout DemiCon weekend. The money raised comes from activities like the charity art auction. Fans and other groups also help raise money.

This year we’ve added an option for you to donate to the DemiCon charity through our Square account, as well as the option for you to generally support DMSFFS community events and education initiatives.
