Gregory Reaves

Founder & Co-Owner, Mosaic Development Partners

GREGORY REAVES has spent more than 30 years working at all levels in corporate and private industries. He graduated from Howard University, Washington, DC, with a BS in Chemical Engineering.  He also played division I soccer in college and two years as a semi-professional player.  

Greg established his career in the pharmaceutical industry by joining McNeil Consumer Products Company, a division of Johnson and Johnson, where he worked as an engineer in support of research, manufacturing and packing operations.  Greg then joined Merck and Co. Inc., where he held eleven different positions during his tenure with the company.   During this time, he led college recruiting for the manufacturing division, directed Government Affairs and Community Relations for five states, headed corporate world-wide media relations, and led Research Communications and Policy.  Greg worked on a multitude of consumer product launches, managed all national and international media relations, coordinated all financial data releases with the CFO and investor relations, and worked closely with the CEO, including on policies that led to the global reduction in pricing of AIDS medicines to the developing world.   

Greg left Merck and joined a mid-size real estate development company, where he was COO and a member of the executive team.  He held specific responsibility for operations, hiring, marketing, public relations, commercial leasing, and government relations.   

Greg then co-founded Mosaic Development Partners, a Philadelphia based, minority-certified commercial real estate development company.  Greg and his partner have successfully helped stabilize neighborhoods, by partnering with municipalities, established developers, not-for-profit organizations, and government entities, to revitalize properties in key, but disinvested, community corridors. Mosaic and its partners have invested more than $200 million directly into Philadelphia neighborhoods and BIPOC businesses, resulting in hundreds of construction and full-time jobs, eliminating blight, and spurring additional investment in those communities.  Along the way , Mosaic has formed creative partnerships, such as Cheyney University, the nation’s oldest HBCU, to reimagine the future of on-campus education through the repurposing of underutilized real estate assets.  Recently, a Mosaic partnership was awarded the rights to co-develop the Philadelphia Navy Yard.  This project represents a 20-year, mixed-use redevelopment comprising roughly 8 million square feet and $5 billion investment in life sciences, new residential housing, hotels, restaurants and other amenity spaces.
