Poets & Quants asked members of the MBA Class of 2015 to share their favorite professors in a feature posted on the site. Olin’s Geoff Nykin, MBA’15, featured as one of P&Q’s outstanding grads named Barton H. Hamilton, the Robert Brookings Smith Distinguished Professor of Entrepreneurship as one of his favorite profs.

“Professor Bart Hamilton, who teaches several economics courses at Olin, challenged me to think differently and always treated me as an equal. Bart wants people to disagree and encourages passionate discussion. I think his classes best reflect the types of real-world conversations that occur in board rooms across the country. One time, Bart and I got into a disagreement over compensation strategies for sales associates. Although we didn’t come to an agreement, I was incredibly impressed with how he debated with me as a peer and greatly valued my perspective.”
