Four teams take the next step in joining one growing, multidisciplinary organization
On September 15th, 2026 Engineering Analytics, 2IM Group, Nelson Geotechnical Associates, and Curran-McLeod officially became MacKay, marking the next step in the integration of four firms that joined the company over the past year.
Engineering Analytics joined MacKay in August 2025, followed by 2IM Group in February 2026 and Nelson Geotechnical Associates and Curran-McLeod in March 2026. Each firm continued operating under its established name during an interim integration period, with the designation that it was part of MacKay.
With the transition to the MacKay brand, the four teams now join colleagues across the company under one name.
“Bringing these teams together under the MacKay name represents an important milestone, but what matters most is what it allows us to do for our clients,” said Derrick Smith, CEO of MacKay. “We are combining exceptional technical expertise, strong local relationships and broader resources in a way that makes our entire organization stronger. As we grow, our commitment to excellent client service remains at the center of everything we do.”
Clients of all four firms will continue working with the professionals and project teams they know and trust, while gaining access to MacKay’s broader network of expertise, services and resources.
The transition also creates a more unified experience for clients, employees and partners. Beginning September 15th, the firms’ digital presence, communications and other branded materials will transition to MacKay.
Together, these teams are moving forward under one name and a shared commitment: Guided by values, driven by impact.
