Since inception, Groundeffects, has successfully created comprehensive development and operations plans for many projects ranging from resort communities, hotel developments, urban renewal projects, independent school facilities and nature based tourism attractions. Groundeffects and its principals are also the founding partners in the Sea to Sky Gondola which is one of Canada’s most acclaimed and successful new tourism attractions. Currently, Groundeffects is working with Groupe Lune Rouge in developing a network of major tourism attractions.

Here is a brief story on the team that makes this happen.

David Greenfield, principal



Prior to starting Groundeffects with Trevor, David Greenfield was most recently Executive Vice President with Intrawest Placemaking – one of the world’s leading experts in resort village creation. He was responsible for all of the division’s real estate development activity in Western North America, including Mexico, Hawaii, and the Pacific Rim.

David began with Intrawest Corporation in 1987. He was one of the original resort development employees for the company and was instrumental in helping Whistler/Blackcomb to become one of the most celebrated mountain resorts in the world. David was also directly responsible for planning, revitalizing and creating the resort village and real estate development at Mont Tremblant, Quebec. This resort rapidly became one of the most successful new resorts in North America and continues to be one of the top travel destinations in Quebec.

In his 20-year career with Intrawest, David was involved at various times in the strategy, planning and development of literally all the resorts in Intrawest’s resort portfolio.

David has a Civil Engineering degree from the University of Alberta and a Master’s of Science degree in Urban Land Economics from the University of British Columbia. He lives in Whistler, BC.



Trevor Dunn, principal



Prior to starting Groundeffects with David, Trevor Dunn worked with Intrawest from 2001 to 2008 , most recently acting as Vice President of Development. He was responsible for delivering the Westin Imagine Orlando, a $130-Million, 315-room condominium hotel. In his development role, he was also responsible for $50 million dollars of asset divestitures that included commercial assets, land, and business entities.

His focus is in these key areas;

  • Tourism attractions operations
  • Operational planning during pre-development to ensure that all the appropriate businesses are factored into the plan
  • Financial and legal structuring to ensure that the operational spaces meet feasible capital returns in the proper legal structure
  • Post-development integration with all of the stakeholders to ensure the operational businesses are successful from the beginning



Trevor served as the initial General Manager of the Sea to Sky Gondola during its first year of operation and is currently serving as the Managing Partner.

Trevor Dunn has an Applied Science degree in Engineering from the University of British Columbia and is active with the Canadian Cancer Foundation. He lives in North Vancouver with his wife Emily and children, Riley Josie and Oliver. When he is not trying to keep up with them, he enjoys running, surfing and exploring.
