Karen Sutherland


Karen has been in love with drafting ever since she chanced to take it as a high school elective. An Architectural Technologist with Crosby Hanna & Associates, she draws on her passion for design and a diploma in Architectural and Building Technologies from SIAST to help the landscape architects and planners take projects from concept to completion.

While much of her days are spent at the computer immersed in AutoCAD, Karen takes care of a gamut of things, ranging from preparing and printing project documents to contract administration, research, and clerical tasks. Somehow she even manages to find time to get a breath of fresh air once in a while on site visits. For Karen, the most rewarding part of her job comes from collaborating with co-workers, clients and consultants to deliver an exceptional end product.
