NSA is pleased to announce our newest associate, Hillary Little. 

Hillary joined the firm in January 2018 as an intern architect. Hillary is known around the office for her quiet demeanor and stealthy sense of humour. She has a fierce eagerness to learn all aspects of the architecture industry, making her a well-respected member of our team. 

During her time at NSA, Hillary has played an instrumental role in several of the firm’s projects including the addition and renovation of the Childcare Centre located at the Jerry McCaw Family Centre YMCA in Sarnia, where she was involved from the design phase through to construction. She has particularly enjoyed working on construction documents for some of our many projects with the Thames Valley District School Board.  

Hillary’s energy and excitement towards her projects make her a joy to work with, and are just a few of the reasons we are thrilled to welcome her as our firm’s newest associate.
