Katrina Grisé


Earning her diploma at the Northern Alberta Institute of Technology (NAIT), Katrina developed a wide array of skills and knowledge that have contributed with her passion for sustainable landscape design. Participating in functions such as map drafting for community planning and creating design drawings for landscape projects, Katrina puts maximum effort into everything she does. As an escape, she can often be found scouring Pinterest for new recipes or DIY (do it yourself) projects and exploring her new city. It’s safe to say that plenty of Katrina’s time is spent problem solving with AutoCAD and entertaining her creative side.

Stephanie Klyne


Certainly she’s fun, energetic and creative, but you’d be hard-pressed to find an adjective that can begin to capture the real Stephanie. A technical school graduate in Media Arts Production, Stephanie has taken her love of photography, film and graphic design and fused them all into an unexpected career as a CAD Technologist with Crosby Hanna & Associates. For an artist like Stephanie, the relaxed, friendly and inspiring atmosphere at Crosby Hanna feels so much like home.

Stephanie’s great sense of humour and contagious, easy laugh instantly endear her to clients and co-workers alike. When it comes to work though, she’s downright serious – applying her artistic passion and eye for detail to every plan she designs. From drawing concept plans for the architects to photographing projects onsite, Stephanie’s creative muscle gets plenty exercise.

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.

The mixture of art, science, and working with people eventually led her to obtain her Master of Landscape Architecture degree. Now, as a Project Landscape Architect with Crosby Hanna & Associates, she is looking forward to the ever-changing challenges of landscape architecture from planting design to project management.
