It begins with a vision.
Dorsay Development CEO Geoffrey Grayhurst has long championed a leadership approach focused on connection, support, long-term value, and intention for the communities we build.
We stand by this commitment to build and develop thoughtful residential and commercial properties, creating spaces where everyone can thrive.
We are thrilled to announce the official opening of the Dorsay Community & Heritage Centre.
A fantastic event co-hosted by the City of Pickering welcomed neighbours and community members into the space – the new home for the City’s Archives, Museum and Library. Featuring community event and meeting spaces, we are proud to have partnered with the City to help bring this beautiful community amenity to life and to help foster conversations, experiences and connections.
Congratulations to the citizens of Pickering. We are honoured to be a part of your story.
