“Without John in our team, we would not have been successful. Without him, and just relying on our turnkey contractor, we would have failed complying with our environmental permit consent, and we would have been forced to restart another project just to correct vendor errors. By having John on this project, I did save a huge amount of capital reinvestment and waste of time and efforts.”

“I worked with John McKinnon for over a year on a particularly challenging capital project and throughout that time John demonstrated an exceptionally positive and focused skill set and attitude. John’s water and waste water expertise was paramount to identifying and addressing engineering and process issues, working with a problematic joint venture supplier and the ‘hands on’ provision of communication and training for the client’s employees. There is no doubt that the project benefited immensely from John’s involvement and the resulting operational efficiencies and effectiveness of the plant were largely achieved by his determination and drive.”
