Flock DC is a real estate management company serving the District proper.

We knew from the start that to take flight, we all need fuel. This core value is at the heart of Flock’s birdSEED philanthropic giving initiative.

Good citizenship and bold contributions to community are part of our wingprint. Our giving began 12 years ago with our time. Indeed, it was all we had to spare. We helped build playgrounds, plant gardens, serve meals and sort clothing. We have (and still) wander the streets with trash bags and lend our spaces to those who have needed to gather, plot and plan for a better world.

These are the seeds we’re planting today as part of a reparative move toward a more just future.

We hope you join us. We have a lot of work to do.
