There were also groups of coworkers who had seen the opportunity and thought it'd be great for their corporate volunteer work.

"We had volunteered with the Denver Rescue Mission before, making boxes, and it really felt like we made an impact, to put all the food together and see it coming together," said Natalie Donofrio, whose employer Ernst & Young suggested the Day of Service for their volunteer program. "So we wanted to get as many people as we could here."

As she and a few dozen volunteers on site worked efficiently in their assembly lines to package boxes of food for senior citizens who live under the poverty line, the impact here at the food bank also became evident quickly.

"It's really fun," Ellis said during a break in the action. "We've got fans, corporations sending employees. We've got players, we've got cheerleaders, a lot of staff members. Everybody's all in today, and I'm really proud of the effort that everybody on our staff [made] to put this together."

It was a large undertaking, and with the goal of celebrating the NFL's 100th season, it had to be — and it just made sense that anyone in the area could take part.

"The NFL is celebrating its 100th season in 2019, and across the country we are working together to bridge the gap between the teams and the cities that they play in," said Allie Engelken, Executive Director of Community Outreach for the Broncos. "Hosting 100-minute service projects here in Denver through a day of service makes us feel closer, not only to the nonprofits that we're serving, but the fans that we're working alongside of to make those projects come to life."

And whether it was at the Food Bank of the Rockies, the Denver Broncos Boys & Girls Club, Big Brothers Big Sisters of Colorado or any of the other nonprofit organizations where community projects were hosted, everyone came away knowing they had done at least just a small part to help improve where they live. Ultimately, more than 500 volunteers contributed 88,700 minutes of service, which has an estimated value of more than $40,000, based on the Independent Sector's Value of Volunteer Time in Colorado.

And this is just the start. The Denver Day of Service will return next year, and you can already count the Ruscettas among those eagerly awaiting the sign-up sheet in 2020.
