What our clients have to say...

The work was completed in four phases that allowed us to move employees in stages, enabling business to continue as usual. This was particularly important to us as we had hard deadlines that affected patient care and R&D project deadlines for new product releases. SGC met each and every deadline.

Jim Nafziger , Director, Systems and Supply Chain

Working with S.G. Cunningham has proved to be – by far – the best contractor relationship we have had in our history. Their attention to detail, adherence to timelines and ability to work around our business operation needs was impressive.

Wendi Campbell , Executive Director
The Food Bank of Waterloo Region

From the moment we issued a Letter of Agreement, George was in full swing. He was able to mobilize within days, communicated effectively and efficiently. He and his team understood how to use their experience to move the job along. By combining our efforts for scope retention and George’s team’s appreciation of our needs, we arrived under budget and on time. This is a level of business trust that cannot be understated, especially in the contracting industry
