David de Lange joined NRG in 2015 as leader of the company's Alberta operations, bringing with him more than 30 years of research experience in government, retail and consulting. Most recently, David was a Senior Associate with the Praxis Group in Calgary where he worked with a wide range of clients applying his skills in the structure, design, administration, and analysis of quantitative and qualitative research projects.

David is committed to providing information that companies, organizations and government can rely on to make decisions in the best interests of their clients, their employees and their stakeholders. Drawing on his experience working for Parks Canada and Calgary Coop, much of his research focuses on understanding and improving how the public and other stakeholder groups perceive and interact with organizations that have an influence on their lives.

David has a Master's degree in Resource Management from the University of Manitoba where his research focus was understanding the dimensions of human behaviour in natural environments. A former member of Canada's National Cross Country Ski Team David has maintained his interest in high athletic performance through his passion for running and fitness. He is a loyal supporter of Arsenal FC, and spends his remaining spare time renovating houses, travelling and despairing about the Alberta weather for alternately baking and freezing his large vegetable garden.
