Growing from Within: A Chat with Greiner Intern Spencer Flattum

Written by Kate Carlson
Greiner Intern Spencer Flattum

“I decided to become a construction engineer because I have always liked building. From growing up doing do-it-yourself projects with my dad and going on volunteer trips to help rebuild homes, decks, etc.”

That was a quote from one of our most recent interns, Spencer Flattum, during his first week with Greiner. It’s hard to believe that summer is almost over, as this fall Spencer will be returning to Iowa State University to finish his degree.

Fortunately, he will continue to work for us throughout the school year at our office in Des Moines. And of course, we are excited to hopefully bring on another intern full-time after graduation!

We sat down (remotely) with Spencer recently. Here’s what he had to say.

As a Greiner Construction intern, what was the most beneficial experience for you? Why?

Working with many different superintendents and project managers who gave me the opportunity to get hands-on experience in the construction industry. They all gave me beneficial feedback/advice on how I approached problems that may arise on the job site.

What new skills, techniques, or knowledge did you gain this summer?

One good piece of knowledge I learned is when both a subcontractor and a general contractor are efficient, they are both profitable in a project. So, when planning on when to bring on subcontractors, it’s important for the general contractor to have everything they need to keep working without slowing down.

One technique I improved on is learning to identify areas where problems are going to arise, so when subtractors come up to you with a problem you will have a solution. With that said, if I don’t know the solution to a problem, it’s okay to tell them I will figure it out and get back to them.

How would you describe the company culture at Greiner?

[Greiner is] A group of highly dedicated workers striving for a common goal—helping the client get the project results they want. To achieve this, Greiner has created a positive, engaging environment where collaboration and hard work is recognized.

What projects were you personally involved with?

I worked on three projects this past summer:

What are your goals and aspirations for the future?

I’m hoping to work my way up to either a Project Manager or Superintendent for Greiner Construction!

What advice would you give to a future intern?

Don’t be afraid to ask questions! Everyone is extremely helpful and are willing to help you learn and grow.

Are you interested in beginning your career in construction with Greiner?

We are always on the lookout for bright young minds with a passion for the world of commercial construction. If you’re a current college student who is interested in joining a dynamic, respected Minnesota-based construction company, send your resume to

What makes Greiner different?

If you are on our team, your opinion is valued no matter what level of the organization you are at. Because to us, it’s not what you’ve done, it’s about what you aspire to do.
