"Alex has proven himself, both in the market--having been involved with some of the largest transactions in the Front Range--and by taking a leadership role with Cresa through his dedicated service on the National Strategic Advisory Board," says Chuck McKenney, co-founder of Cresa Partners, which specializes in representing tenants.

During his career Hammerstein has completed more than five million sf of tenant representation assignments, including "complex and demanding situations." Those assignments include headquarters relocations, facilities consolidations and lease restructures, according to McKenney. His client list includes Array BioPharma, DigitalGlobe Inc., CSG Systems, Global Healthcare Exchange, Regis University and Spyder Active Sports.

"Alex is talented and experienced, a perennial top producer in our company," says Marc Lunde, another partner in the firm. "Alex is recognized for representing high-profile clients; his contributions to our company have been invaluable."
