“She’s one of the most prominent designers from Canada. Her vision is to create original architectural spaces with special emphasis on scale, texture, color and proportion within the frame of her clients’ needs.”
Cosentino Magazine

“Theresa was involved in all aspects of the project from architectural design through to interior design including art curation. She was extremely collaborative and responsive at all times throughout the project. She has an eye for detail and demands quality and perfection in every facet of the design process. We are beyond thrilled with the final result!” 
– Esther & Stuart Waugh, Clients

“Theresa Casey reveals her belief that design is about feeling. The Toronto-based interior designer is not interested in rooms that are “done”. To this end she works the shapes, proportions, textures and light into a harmonious balance.”
– Janice Lindsay, The Globe and Mail
