Team
Lori Sellmer
Principal Designer & Founder
Lori was born and raised in Calgary and found her passion for design at a very young age. She never wavered in her commitment to the field of residential design. As an award winning design student, she graduated as an architectural technologist from the Southern Alberta Institute of Technology. Working for one of Calgary's largest homebuilders she honed her skills in both drafting and interior design.
With over 20 years of design and interior decorating experience, Lori's clients are supported with an extensive construction and design know-how. A love for travel and zest for life is evident in her structured, classic, yet slightly eclectic design style. After living overseas for three years, you can always find her ready to hit the road in search of new inspiration.
Sarah Barnes
Interior Designer
Sarah brings a combination of technical precision and creative flexibility to her role at Lori Sellmer Design. With a background in finance and consulting, she was drawn to design for its problem-solving and detail-oriented nature. She supports projects from early millwork drawings through finishes, lighting, and furniture layouts, translating strong ideas into refined, personal spaces. Her design philosophy is rooted in what lasts, favouring thoughtful layouts, enduring materials, and details that make everyday life easier. Outside of work, she’s often with her red golden retriever, Goose, at pottery class, or on the golf course with friends.
Mahalia Lokhorst
Interior Designer
Mahalia’s background in psychology and hospitality informs her approach to movement and function within a home, ensuring each space feels intuitive and effortlessly livable. She contributes to every aspect of a project. From thoughtful space planning to selecting materials, and layering in finishes while simultaneously designing built-in components and intricate details, she ensures that every element works together seamlessly. Outside the studio, Mahalia is a wonderful mom to two young children. She enjoys adventures with their Great Dane, Triton, skiing in the mountains, and expressing her creativity through watercolour painting and poetry.
“At Lori Sellmer Design we focus on providing original and inspiring interiors for custom new build homes and large scale renovations. I work closely with my clients to find out who they are and how they live. I love to be there for them from the first design drawings, all the way to the last toss cushion. I strongly believe that having the best client relationships leads to the most beautiful outcomes."
