Superintendent gives top marks to CANCO team

As the Sioux Center Community School District prepared to open its brand new, $42 million, 180,000 square-foot high school building, Superintendent Gary McEldowney had only good things to say about Carl A. Nelson & Company and the value the firm brought to the project in its role as construction manager.

The superintendent also offered a complimentary critique of the Carl A. Nelson & Company construction management project team. You can watch that video here.

BONUS: The project architect had some pretty nice things to say about our leadership, too. That video testimonial is here.

“... if it went like this again, I’d be willing to start tomorrow to do this again, because I felt supported along the way. ... Trust was established very quickly, and was carried out through the end of the project.”

Gary McEldowney, Superintendent, Sioux Center CSD, Sioux Center, Iowa

CANCO comes through on high school renovation project

In this brief testimonial video, Shenandoah Community School District Superintendent Dr. Kerri Nelson discusses the benefits of engaging Carl A. Nelson & Company as construction manager on a project that resulted in a multi-million dollar renovation of Shenandoah High School. Visit our YouTube channel for the full-length video, which also addresses project history and our project team.

Read more about the project, and see a collection of before-and-after photos, in CANCO News.

“I would recommend (Carl A. Nelson & Company) to anyone. I would stand behind their work, because I have seen the quality. I know they follow through with their commitments. And they’ve done well in Shenandoah, and they’ve served our community in an outstanding way.”

Dr. Kerri Nelson, Superintendent, Shenandoah CSD, Shenandoah, Iowa
