About

Prof P is Nathan Preheim—Entrepreneur. Investor. Educator.

I teach entrepreneurship the way it actually works: through action, not theory.

Clear thinking. Practical frameworks. Real execution.

The Approach

Built at Creighton

Developed inside the Greisch Center for Enterprise Value, Creighton's cross-campus hub for entrepreneurship and innovation.

Open to all majors, this is where students don't just study entrepreneurship, they practice it.

Students are:

launching ventures
building side hustles
testing ideas in the real world
leading innovation inside organizations

Where it happens:

in the classroom
through applied learning
in research labs
across campus events designed to turn ideas into action

Why it matters:

The future belongs to people who can create value, who can spot opportunities, test ideas, and move quickly.

That's what students build here.

They graduate with more than knowledge. They leave with momentum.
