Colleen Mahaffie

Marketing and Communications Manager

The ability to communicate clearly and effectively is a foundational skill, which Colleen saw in her youth as a camp counselor with toddlers and as a tutor to high school students. She graduated from Villanova University with a Bachelor’s degree in Communications and worked in marketing for travel and interior design before finding her place in the impact sector. Colleen worked for an environmental nonprofit, Forests Ontario, prior to joining CSI as the Marketing and Communications Manager. Putting people and planet first is a core value for Colleen, and one that she is happy to embody at CSI. Here, she works closely with the team to manage the external communications of the Centre and helps to market its many offerings, ideals, and members. She also has a passion for good design, typography, and the Oxford comma.

Colleen moved to Toronto from the beautiful green mountain state of Vermont. You can usually find Colleen hanging with her rescue pup, Bennie, and exploring the many neighbourhoods of Toronto. She’s always happy to chat about craft beer, politics, and Grey’s Anatomy.

We’re excited to honour and recognize the First Nations, Métis, and Inuit peoples as we celebrate National Indigenous History month in Canada. We’re building on the Indigenous-led innovators that we highlighted last year, spotlighting CSI members and alumni whose work centres and celebrates Indigenous communities, and supports reconciliation.

Today, CSI celebrates the 18th anniversary of opening our doors as Canada’s (and maybe the world’s!) first coworking space. Of course, we’ve evolved over the years to become so much more than just that - we are a curated, tight-knit community who cares deeply about making the world better for all. To celebrate the past 18 years of partnership and social innovation, we picked just 18 milestones (from the thousands of star moments) to share.
