Lemonis heard of the town after an 88-year-old store owner in Horton was arrested last month for not repairing hazards to his store.
The town has moved past the arrest, but now is focused on revitalizing a downtown that has empty store fronts and struggling businesses.
As part of his philanthropic efforts, Lemonis works to fix small businesses. After hearing about Horton, he decided to fix a town.
"What it's going to take is a complete downtown main street overhaul," Mayor Tim Lentz said.
After meeting with the city, Lemonis donated $150,000 to update the town.
He is hoping for a fundraising goal of $1.2 million to complete everything. They will seek donations from local businesses.
One of the few remaining businesses in town is the English Leather Shop, at its same location since 1959.
"What I would really like to see is the strengthening of the services and kind of draw them in and bring them to one location," Owner Luke Pollock said.
Lemonis will return to Horton in the next few weeks to see how progress has come.
