About

Callum Harrington

Callum Harrington founded Bold Citadel Lab in Chicago in 2017 after eight years at two large professional services firms, where he led strategy and operations engagements for clients in manufacturing, logistics, and financial services.

Before consulting, he spent three years as a director of operations at a mid-size distribution company in the western suburbs of Chicago, an experience that gave him a working knowledge of what strategy documents look like from the inside of an organization trying to implement them.

He holds an MBA from the University of Illinois and reads more organizational psychology than he probably admits to clients. He lives in Chicago's Lincoln Square neighborhood with his family.
