About Us

"We are excited to announce that our company name will be changing to HECO Engineers.  We all live in a world that is continually adapting and changing.  Our name change reflects Holladay Engineering’s tradition of responsiveness to our clients through expanding the depth and range of our engineering services. Holladay Engineering has established a reputation of providing our clients with responsive, quality, engineering services, tailored to their specific needs.  As we rebrand our company, there has been no change in management and we will continue to provide the same elevated level of service on which we have built our reputation."
