Lily Viggiano

Senior Project Manager

Lily Viggiano is driven by a profound belief in fostering an accessible, equitable and just society for all.  As GreenHouse’s Senior Project Manager, Lily created and leads Changemaker Labs, a program that invites changemakers from across the Waterloo Region to come together and take climate action. This initiative is aligned with Canada’s goal of achieving net zero emissions by 2050 and operates an intergenerational participation model. In her previous role at the Halton Youth Initiative, she empowered over 300 young leaders to make meaningful community contributions. With a focus on developmental relationships and leveraging assets, Lily mobilized a dedicated group of adult allies that played a vital role in the project’s success.  A recognized expert in youth engagement, she was seconded by Volunteer Canada to develop a youth engagement curriculum for the Canada Service Corps. Lily has a Bachelor of Public Relations from Conestoga College.
