Petar Sesar


Petar is a recent addition to the firm, starting in September 2018. He attended Fanshawe College's Architectural Technology program, graduating on the Dean's Honour Roll in April 2011. In addition, Petar is currently completing his Diploma in Architecture through the RAIC Syllabus and Athabasca University. 

Before he joined Nicholson Sheffield Architects, Petar worked for Global Affairs Canada, where he worked on projects for Canadian Embassies and official residences abroad. He also worked for Watson MacEwen Teramura Architects in Ottawa, where he oversaw all phases of project construction, from concept design to contract administration. Petar offers a wide range of experience, having worked with new and existing build, as well as with heritage buildings. 

Not only is Petar a successful technologist, he is also a talented photographer, and is proficient in AutoCAD, Revit, SketchUp and Adobe Design Suite. We're very excited to have Petar's depth of experience and collaborative attitude around the office!
