Dillon Consulting Limited (Dillon) has entered into a partnership with David Nairne + Associates Ltd. (DNA).
DNA is a multidisciplinary consulting firm providing planning, architecture, civil and structural engineering, and project management services that has been in practice since 1972. Dillon is an engineering, planning, management, and environmental science firm that was founded in London, Ontario in 1946.
“We are excited to partner with the incredible team at DNA,” said Sean Hanlon, CEO and president, Dillon. “When we looked at DNA, we saw a firm that genuinely shares our passion for nation-building and community improvement projects. We deeply respect the 50-year legacy of trust and loyalty DNA has built, and together we will continue to live our shared mission to elevate value every day for our clients.”
DNA is highly recognized across the West Coast and Northern Canada for its deep, meaningful relationships with Indigenous communities and leaders, as well as its work with municipalities, non-profit organizations and federal, provincial, and territorial governments. The DNA team includes architects, engineers, and planners who approach every project with the mindset of community builders, combining their expertise to improve quality of life and infrastructure. DNA will continue to operate separately from Dillon Consulting Limited as David Nairne + Associates Ltd.
“I’m deeply honoured for the opportunity to build on the legacy established by my father, David Nairne, and Fereydoun Dabiri,” said Kathryn Nairne. “Their leadership, vision, and commitment have laid an exceptional foundation, and I’m excited to help carry that legacy forward while shaping the next generation of our success.”
Following Dillon’s March 2025 partnership with Atlantic Canada’s FBM Architecture Ltd. (FBM), the alliance with DNA represents the western expansion of Dillon’s architectural subsidiary, Dillon Architecture Limited (DAL). With FBM anchoring the practice on the East Coast and DNA driving capabilities in the West, DAL is positioned to provide a connected, coast-to-coast presence that dissolves traditional boundaries and delivers premier architectural design backed by Dillon’s full suite of multidisciplinary consulting services.
