It is thanks in part to a $35,000 grant from the NFL Grassroots Program.
Packers President and CEO Mark Murphy presented the check to Manitowoc Lutheran High School.
"It brings so many people together for Friday night games, Saturday afternoon games. It is a real source of pride for communities" Murphy says.
MLHS is one of only 17 schools in the nation awarded the funds.
The field re-model included a new fence, and brand new bleachers to replace old wooden ones that had fallen out of code.
With the upgrades, the school is now WIAA approved to host playoff games.
"That is exciting, we were five seed this year so we did not get to host any but not only to host our own games, but we can be a neutral site host. The city of Manitowoc has three high schools and prior to this only one met WIAA standards to host a playoff game" explains Scott Reinhard, Development Director at Manitowoc Lutheran High School.
Renovations are about 90 percent finished.
The total cost for the project was $110,000.
