🥞🧇 The Batter Battle! 🧇🥞

In honor of Employee Appreciation Day, we “flipped” the script with a little friendly competition: Waffles vs. Pancakes!

(Or, at Team Timberline: Walter vs. Walters! 🤣)

Team Waffles says those crispy edges are the GOAT.
Team Pancakes insists fluffy stacks are the true breakfast champion.

So the real question is… who do you think won?! 👀

Either way, we celebrated the real stars of the show—our amazing team. 🙌

Timberline continues its commitment to community engagement with another Adopt-A-Highway volunteer cleanup.

We were lucky enough to get out again before the snow started flying and picked up another several bags of trash from our local roadways!

In 2025, Timberline made a commitment to increasing employee engagement in our community through volunteer opportunities. Our goal was not only to build a stronger connection to our community, but to build stronger connections among our employe owners as well!

Last week, we had the pleasure of doing our very first cleanup as part of the Adopt-A-Highway program. We look forward to future opportunities to serve our community and our employee owners!

⚾️ Last Saturday, Team Timberline enjoyed an evening at the ballpark – Veterans Memorial Stadium - celebrating hard work, collaboration, and the incredible people who make it all happen.

⚾️ Although our beloved Kernels lost by a single run, we shared laughs, cold drinks, good food, and a warm but beautiful Saturday evening together.

⚾️ We are reminded that great teams thrive on connection, both inside and outside the workplace.

Thank you KCRG-TV9 and Jackson Valenti for sharing this perspective.

Even though President Trump’s steepest tariffs aren’t in effect during the 90 day pause, manufacturers in Iowa are still preparing for potential changes.
