Our Leadership

HAWA Engineers is led by a group of principals and associates, each with experience in the design and construction of mechanical, electrical or telecommunication systems. The emphasis we place on the expertise of our staff is seen in the number of registered professionals— who average more than 25 years of experience — on our team. Our high ratio of registered engineers reflects our niche of providing engineering services on unique and complex projects.

Project managers are the critical link between our design staff and other members of the project team. Project management responsibilities include making sure all customer project goals are met within budget and on time, managing day- to -day activities and recommending engineering solutions consistent with the planned usage and life cycle for each facility.


Management, marketing, finance and quality control provide essential reinforcement for our exceptional team. Through research and support, both detailed and large scale, this leadership group helps HAWA project managers and team members understand the businesses of our customers. This, in turn, helps us serve all our customers better.
