Our Spencer office spent a day painting two Y's Service Club Clay County Fair Nutty Bar stands for their 2026 Iowa Society of Certified Public Accountants Month of Service project!

Here’s a quote from Wes about the experience: “Most of the paint made it onto the stands, but a little ended up on us too. It was a warm day, so we wrapped up the project with some well-earned time in the shade. We are grateful for the opportunity to serve our community!”
