We aim to deliver professional engineering services that efficiently meet our Clients' technical requirements and high expectations for quality and value.
Our Team
Our current staff size is 45. We have 11 registered Professional Engineers on staff, including 5 Designated Consulting Engineers. Seven of our senior staff are LEED Accredited Professionals. This high ratio of professionals to staff translates into the delivery of a particularly professional service to our clients. John Bisset remains active in the firm, mainly involved in special projects. Everyone on our management team is actively involved in engineering. We believe ownership is strongly linked to the quality of our engineering services. A cornerstone of our ownership structure is the ongoing process of senior management succession, ensuring that the company’s quality and culture have a broad base within the shareholder group.
