He was diagnosed with a rare form of cancer in 2011, called Neuroendocrine.
Doctors found five tumors in his stomach.
After surgery and treatments, the cancer is back, and doctors say the treatment he needs can only be found in Europe.
"It's horrible, it's horrible. But, this is something we can do to help take a little bit of the stress off him to help him pay for the treatment that he needs," said Jenny Miller.
The trip costs $45,000, and that's why everyone is "Jammin' for Jerry."
This is an event his family and friends decided to put on, to raise money for trip's expenses.
"I balled the day the girls told me about today's function, and all the stepping up that everybody's been doing and it was overwhelming. It's absolutely overwhelming," said Kimberly Etzler.
There was food, raffle tickets for different prizes, shirts, and much more.
"People are so generous, and giving and kind, and it gives us hope that we can get there on our fundraising goal. We're very appreciative," said Miller.
"Even a lot of people we don't know. Friends of friends in the community, stepping up behind us, it's amazing," said Jerry Etzler.
The family has already raised $17,000.
They are confident this event will help get Jerry the treatment he needs.
"Not in a million years could you ever say you don't know what you've done for our family," said Kimberly Etzler.
Donations for the Jerry Etzler fund are being accepted at any Nodaway Valley Bank.
