🎉 NEW MACHINE DAY AT KOESTER CORP! 🎉

Koester Corporation is excited to welcome two new additions to our CNC machining department:
🔹 Haas TL-1 Toolroom Lathe
🔹 Haas ST-25Y CNC Lathe with Live Tooling

These investments increase both our capacity and capabilities, allowing us to machine more parts, reduce lead times, and tackle increasingly complex projects for our customers.

The addition of the ST-25Y's live tooling capabilities means more operations can be completed in a single setup, improving efficiency, accuracy, and turnaround times.

At Koester Corp, we're committed to continually investing in the equipment, technology, and people that help us better serve our customers.

Today, Koester Corp celebrated the retirement of our oldest employee, Gary Brumbaugh. At 84, Gary can still outwork someone half his age and can simply be described as "a quality human being."

Thank you for all your help, Gary. Enjoy retirement!

Yesterday, Koester Corporation celebrated the retirement of Brian Ruen, a dedicated team member with more than 39 years of service.

Brian began his career at Koester as a wireman in the panel shop, went on to QC control panels, and later transitioned into the role of electrical engineer. Throughout his career, he specialized in electrical CAD design and consistently stepped up to do whatever was asked of him — always at the highest level.

Brian’s commitment to quality and integrity is best captured in his own words:

“It’s better to do things the right way than to do things just to get them done.”

Thank you, Brian, for your years of dedication, craftsmanship, and the standard of excellence you leave behind. Best wishes in your well-earned retirement!

🎄 Merry Christmas from Koester Corporation 🎄

Last week, Koester Corp celebrated the Christmas season with a catered lunch for our team — a chance to slow down, enjoy good food, and spend time together.

To add a little extra holiday cheer, employees had opportunities to win gift cards, Koester apparel, and even Vacation hours as a thank-you for the dedication and hard work they show throughout the year.

We’re grateful for this incredible team and wish everyone a Merry Christmas and a happy, safe holiday season!

Yesterday, our team gathered for a company lunch to celebrate the season — and to reflect on what we’re genuinely grateful for.

During the meal, our President shared a message that perfectly captures who we are as a company:
Koester Corp is thankful for both the long-time team members who built our foundation and the new faces who bring fresh ideas, creativity, and problem-solving into the shop every single day.

Wishing everyone a safe, joyful, and restful Thanksgiving!
