Community is at the heart of everything we do at CA. We’re dedicated to helping all people in Columbia thrive through opportunities to be healthy and connect with their neighbors.


We recognize that diversity enriches our community in powerful ways. CA is committed to celebrating our differences and advancing a culture of growth and learning.


CA is rooted in the long-held value of inclusion. We’re continuing to build a community where everyone feels welcome and experiences a true sense of belonging.


As environmental and financial stewards, we are proactive and intentional in caring for our community’s resources. We don’t engage in stewardship alone – it’s a shared and collaborative effort.


Together, We are building Columbia's Future

What makes Columbia truly special is an ongoing commitment to the vision espoused by James Rouse, our founding father. At Columbia Association, we consider ourselves keepers of Columbia’s vision.

Together — with your input and commitment — we will keep Columbia the special community that James Rouse envisioned.
