Mahsa Tamadonfar


Mahsa joined Montgomery Sisam in 2020 with experience in all phases of project development. Her previous work has included projects of many different scales across the retail, hospitality, and residential sectors.

Mahsa’s ability to adapt easily to change allows her to work on several projects concurrently without compromising the quality of the work. She has demonstrated this time and again as an integral member of many of our long-term care teams. Her projects include, among others, new long-term care homes for Sienna Seniors Living, Arch Corporation, Humber River Hospital and Trillium Health Partners. Her responsibilities have included coordinating and managing the Revit model and drawing outputs, and designing and coordination building interiors, assisting with finalizing the interior design and selecting finishes.

Mahsa has a great interest in the intersection of health care design and behavioural science. And she continues to seek out opportunities to learn more about the intricacies of architecture for speciality care.
