Greg Ohlhues manages and leads the Architectural and Engineering Design office in St. Paul, Minnesota, where Haskell works with large and small private-sector businesses within the U.S.A. and globally, as well as to local, state, and federal government agencies.

Greg joined Haskell in 2017, bringing unique insight into clients’ needs after 25+ years of experience in engineering and operational roles with notable companies such as Hawkins Inc., Koch Industries (Flint Hills Resources), and Cargill. Having held leadership positions within these various industries has allowed Greg to achieve the strategic task of building an Engineering Group from the ground up to support his previous employers’ internal customers. His project work has led him across the country with his crowning achievement building a brownfield chemical plant over multiple years. He now brings the same leadership and candor to Haskell’s clients to achieve equally remarkable results.
