She has more than 25 years of experience in developing, implementing, delivering and managing energy and environmental education programs for youth and teachers.

Diane Kashuba is the Fund Development Manager with ACEE, bringing nearly 10 years of experience partnering with donors to make a bigger impact. Her passion for the outdoors and her passion to connect donors with amazing, worthwhile causes have come together wonderfully in this new role. As Fund Development Manager, Diane helps ACEE diversify its revenue through strategic fund development and donor stewardship. Prior to joining ACEE, she completed her Masters at University of Guelph in Consumer Behaviour. Then, leaving industry for a role at a large NGO, Diane went on to create engagement opportunities that shared emotion and information - touching the hearts of Canadians, and encouraging action. She helps children, youth, adults, professionals and corporations connect meaningfully with the cause. Diane and her family continuously seek outdoor opportunities at the river, mountain or campground. Email: Diane[at]



Laura Hughes joined the ACEE team in 2017 as the Youth Coordinator for Climate Change and Energy Education. Laura brings two years of energy conservation outreach experience to the team, as well as two years’ experience in international environmental conservation, primarily in the Caribbean and the South Pacific. Most recently, she lived with a tribe in Papua New Guinea as she studied environmental economics and climate change impacts in low-lying islands of the South Pacific. Laura completed her MSc in Environment and Resource Management at the Vrije Universiteit in Amsterdam in 2016 and has an undergraduate degree in Geography from UBC. Based in Calgary, Laura can be found at yoga on weekdays and climbing mountains on the weekends. Email: Laura[at]


Marie Tremblay joined ACEE in May 2018 and brings to her new role a dual passion for education and the environment. With university degrees in engineering, education, environmental design (Master’s) and ecology (PhD), it’s fair to say she also has a passion for learning. Marie’s professional experience includes over a decade of teaching in a variety of settings from grade 1 to university level, including five years in Indigenous communities of Canada’s far north. Marie has also been an active member of Alberta’s environmental community for over two decades as a graduate student, conservation scientist in the government and non-profit sectors, and board member of Nature Calgary and Alberta’s Prairie Conservation Forum. Marie lives in Calgary and when she is not working loves to explore southern Alberta’s diverse natural environments by foot, ski or paddle with her family and friends. She is also an avid cyclist and proud mother of two delightful young men, Eric and Alex. Email: Marie[at]

Diana Kurila joined ACEE in June 2018 as a summer intern. She is entering her fourth year at Mount Royal University in the B.Ed program and is passionate about science and environmental education. Diana found her calling after becoming a Students on Sustainability volunteer, where she focused on inspiring students to take action through energy use reduction, wildlife conservation, and vermicomposting. With ACEE’s support, Diana was able to impact ten Calgary classrooms. Diana will be reviewing and upgrading ACEE's teaching resources and database in order to create easier access for teachers. Diana lives in Calgary and loves to volunteer and challenge herself in new ways. Email: Diana[at]
