Our History

At Witzel Dyce Engineering, we work collaboratively, which allows us to exchange ideas and knowledge. This in turn ensures that our clients receive solutions that are cost efficient and effective. We take pride in our reputation as being practical and efficient designers and managers.

Witzel Dyce Engineering was founded in 2013 by David Witzel and Brian Dyce in Kitchener-Waterloo, Ontario. Since then, we have been fortunate enough to grow our firm to now include eleven skilled engineers and project managers. The quick growth we have experienced over the last few years was not what we had intended when we started the firm in 2013. However, we have managed to grow our firm to meet the expanding needs of our core clients while maintaining high standards of quality and service.

Our growth has allowed us to take on larger and more complex projects while ensuring that we are still able to meet the needs of our smaller clients and projects.
