Klein & Hoffman introduced Ampy, a bright orange ampersand, as a cultural cornerstone and recognizable icon of collaboration.

At Klein & Hoffman, we work collaboratively to deliver value-driven architectural restoration and structural engineering solutions. Innovative yet practical, we listen to you, develop creative solutions, and find ways to go from “no” to yes.” Since 1953, we have worked with building owners, campus and facility managers, condominium association boards and architectural firms, putting our client’s best interests at the forefront. Pragmatic and practical, we push the envelope while being mindful of budgets, consistently delivering superior results in high-rise buildings, campus environments, condo buildings, and famous landmarks, including the Shedd Aquarium, O’Hare International Airport, and Loyola University.
