SVP, People and Culture

  • I have had the privilege of working for DC since 1996 and proudly hold the honour of being the company’s first employee. Working with DC since the beginning has allowed me to learn the company from the ground up. It has been extremely rewarding to see our team grow and to be given the opportunity to serve so many interesting clients. Building a healthier and safer world is important to me because I know from personal experience the tragedy of losing a loved one to a workplace accident. Outside of work, I have a degree in history from Carleton University. Spending time outdoors, running, reading and genealogy bring me joy. I love spending time with my husband and our two children.
