J. Mac Willett

As founder, president, and principal engineer of Willett Engineering, a Gray company, Mac’s primary responsibility is the review and management of all structural consulting services offered to Willett customers.

His design profile includes structures ranging from single-level commercial complexes to multi-level office structures, K-12 schools and campuses, film studios, warehouses, manufacturing facilities, and more. In addition, Mac’s work encompasses consulting to the precast and concrete industry, analysis of existing structures, plans review, design of concrete formwork, design of special structures, specification preparation, and construction observation.

Mac has also been involved with many projects requiring the investigation of existing structures for modifications and/or repairs. He is familiar with an array of construction methods used in the past and has analyzed structures over 100 years old. Some of these projects have required the development of new methods of structural problem solution and retrofit techniques.

Mac is involved in his community and volunteers for his local YMCA. When he is not working, he enjoys exercising, reading, and supporting the local high school basketball team.
