From Intern to Leadership

Sam Brockshus, PE

I began my journey at ISG as an intern in the Storm Lake office, gaining experience in surveying and civil engineering while completing my degree at Minnesota State University, Mankato. After graduation, I transitioned to a full-time position at ISG’s Mankato office.

From the start, I was embraced in a collaborative and supportive environment where team members were eager to share their expertise and answer my questions. Over the past 10+ years I have steadily progressed in my career, earning the role of Structural Engineering Practice Group Leader.

"As someone who started as an intern, it was motivating to see ISG's investment in career trajectories, playing a role in growth and success for everyone, no matter their role."

ISG Design Competition

ISG's Design Competition invites university students to showcase innovative, community-focused design solutions. Finalists have a chance to win $1,500 and gain recognition as future design leaders.

Congratulations to the 2026 winner, Devin Johnson, an landscape architecture student at North Dakota State University.

2nd Place: Rajesh Sarker – South Dakota State University, Architecture
3rd Place: Shima Goodarzi – North Dakota State University, Landscape Architecture

"The projects submitted to the ISG Design Competition were all quite impressive in their creativity and conceptual clarity. The winning schemes, in particular, combined strong concepts and thoughtful details, using both natural and architectural elements to solve functional problems and create elevated human experiences. The graphic and verbal presentations were a pleasure, as well. Congrats to all!"

– Beret Dickson, ISG Director of Design, 2026 ISG Design Competition Judge
