Board of Directors

Christina recently returned to Nova Scotia after 9 adventure-filled years in the Yukon, including 4 years as the Executive Director of the Yukon Conservation Society. Her professional experience has been in sustainability and the environment: management of renewable resources, land use planning, climate change adaptation, and advocacy for wildlife and habitat protection as well as energy conservation and renewable energy. She is passionate about finding interdisciplinary solutions to the interconnected social, environmental, cross-cultural and economic challenges we face today.  After many years away, Christina is excited to live by the ocean again and find ways to connect deeply with the land and people of Nova Scotia.

Helga Guderley made St. Margaret’s Bay her home since retiring in 2010 from being a professor of comparative physiology at Université Laval for 30 years. She continues to teach graduate students at Dalhousie University because the amazing variety of physiological adaptations of living organisms continues to delight her. Helga became involved with environmental advocacy shortly after arriving in Boutiliers Pt., fighting the clear cutting on nearby Crown lands. The strong support of her petition against the use of biomass for power generation started her collaboration with the Ecology Action Centre, in particular the Wilderness section. The EAC’s work in its various departments has consistently impressed her and she looks forward to working more closely with the organization.

Helga was born in Dayton Ohio, to recently arrived German immigrants. She did her PhD in Zoology at the University of British Columbia where she met her husband, John Himmelman. They have two grown sons and a lovely little grand-daughter. They look after a mix of gardens and forest in Boutiliers Pt. and enjoy being near John’s homelands along the La Have river. She enjoys hiking, biking, swimming, being in natural landscapes and knowing the names of the plants she sees.

Dawn was born and has lived most of her life in Halifax. Her early career was in the field of nutrition where she worked as a clinical dietitian in both Alberta and Nova Scotia. Having completed a Master in Health Administration, and training as a leadership coach Dawn enjoyed several roles in the NS health system in the areas of staff wellness, leadership development and coaching, and change management. Throughout her career Dawn fostered a systems view of how living-systems like teams, organizations, forests and oceans actually behave as a means to achieve lasting change. An eco-system view of life continues to be Dawn’s sweet spot in retirement as she engages in volunteer opportunities that contribute to enhancing the health of the planet. Dawn is a life-long nature enthusiast and is most happy on her bike, on a seaside hike or on the golf course.  She can also be found on her yoga mat as the sun comes up.

Having grown up in New Brunswick, studied in Montreal and lived for 18 years in Amsterdam, Rhiannon moved to Halifax in August 2018 after spending a year on a 44’ sailboat travelling with her family.

Rhiannon has spent her professional life working on the end-to-end supply chains of international corporations in food and consumer goods manufacturing and retail, most recently as a senior executive, board member and company director. Driving transparency, accountability and implementing strategies and practices to address these issues has been an important focus of her work.

Keith MacMaster is a lecturer and Ph.D. Candidate at the Schulich School of Law, Dalhousie University. He holds a Master of Law degree from Dalhousie and an MBA from the Richard Ivey School of Business at Western University. He concentrates on legal issues in environmental finance for banking and ocean-based industries, especially working on problems of seabed mining.
