Dustin Dilts

MLA, BEnvD, MALA (Associate) 

Dustin’s approach to design draws on the importance of found conditions in decision making. Dismissing the idea of site as a blank slate, he believes it is the existing conditions of a site that are worth taking the extra time to investigate, a process that must occur prior to the implementation of design decisions that seek to remove or make new. Dustin understands that looking deeper into a place leads to a greater respect for what is already there; it is only through careful, immersive study that design can truly enhance what we already have. 

Dustin brings this philosophy to his role as part of O2’s design team. He is fluent in all phases of the design process, from conceptual design to contract administration. Through his work in planning and the public realm, he has developed an expertise in urban design, regional planning, active transportation, and public space design. Dustin has also volunteered on multiple not-for-profit boards.

While completing his Master of Landscape Architecture degree at the University of Manitoba, Dustin gained valuable experience collaborating with Berlin-based competition adviser [phase eins] on the institution's campus planning design competition. His graduate research was driven by the concept of landscape as a fundamental infrastructure, informing spatial and ecological conditions of subsequent built form. His practice reflects this understanding of precedent and values landscape as something which is working and active.  



Kerry Thompson


Kerry holds a Master of Science in Planning degree from the University of Toronto, where her studies focused on land use planning and policy.

She also holds a Bachelor’s degree in Geography, with a Minor in Environmental Studies, from the University of Victoria.

Kerry has professional experience in the public, private and non-profit sectors. She has provided land use planning services in British Columbia and Alberta, where her strengths in research, analysis and communication have enabled her to support multi-disciplinary teams on a wide variety of projects and consultation events. Kerry also worked for several years in the green building sector, providing support for home energy evaluations and government incentive programs.
