In 1998, a young woman named Shannon Passero planted a seed in the maze of streets that make up Chiang Mai, Thailand. She worked tirelessly for almost two decades, bringing her designs to North America, Europe, and Australia. She traveled the world for inspiration and designed in Canada and manufactured in Thailand.

In 2013, in downtown Thorold, in the heart of Niagara, she opened her first stand alone retail boutique in a 200-year-old Firehall and then expanded it again in 2015 and called it the Post Office by Shannon Passero. The store is now 6500 square feet on the main floor of a historic building that has been recognized by the National Trust of Canada for its historical significance in Canada.
