Mosaic Development Partners
Transforming Neighborhoods....One Block At A Time





Our approach:

No ego. No nonsense. No procrastination.

Whether it’s a building or a vacant lot, we ask ourselves the important questions:
Will our results leave the community in a better place than when we began?
Will our ideas lead to greater sustainability?
Do we have the right team to ensure that we can turn our ideas into reality?

What we do:

Mosaic Development Partners develops commercial real estate, identifying real estate projects that have the potential to bring positive change to a community. With job creation, diversity, and community acceptance in mind, we partner with those who share our vision and add value to a project: an experienced developer, a construction manager, or a community group. Where others fail or give up, we find innovative solutions—subtle or radical—that help bring a project to fruition.

About Mosaic Development Partners

Established in 2008, Mosaic Development Partners started its journey to help revitalize communities in one of the most difficult economic times in the history of real estate development. Leslie Smallwood–Lewis and Gregory Reaves remained persistent, faithful and focused on improving communities through the redevelopment of real estate. Then and now, we focus on building new ideas, especially in locations where solutions aren’t obvious.
