FOUNDER & PRINCIPAL CONSULTANT
Built on the inside. Built for owners.
Most consulting firms tell you what you could do. Nicholas Gan, P.Eng., PMP, has spent 13 years on the other side of the table — managing capital programs, leading design and construction, building asset management strategy, and operating the asset afterward.
As former Manager of Engineering at the Region of Peel, Nick led teams across asset management, condition assessment, design, construction, and program delivery — scaling capital throughput from $1M to $100M+ annually. GCG brings that full owner-side spectrum to every engagement, across all five service lines.
