Mortenson Development Inc.

His ability to fill Mortenson's pipeline with more than $500 million in hotel work moved Nate Gundrum to the head of his class last year, when he was tapped to join the firm's Advanced Leadership Development Program, which prepares employees for senior management roles. Colleagues credit Gundrum with strengthening Mortenson's relationships with hotel brands, operators and debt and equity partners. Among his more notable projects is Marriott at HarborCenter, part of a $160-million mixed-use facility in Buffalo, N.Y. In his native Minneapolis, Gundrum is active in a Big Brothers program and has participated in the Middleton Outreach Ministry, a program intended to prevent hunger and homelessness by providing community members with food, clothing, housing assistance and emergency financial assistance, among other services.
