From Startup to Standout: How NBIC Helped Luminary Turn Systems into Sustainable Growth
When Celisa Webster first joined the Nashville Business Incubation Center’s (NBIC) Groundwork program in 2020, she didn’t just want to build a cleaning company; she wanted to build a community of excellence. She already had purpose: a passion for excellence, integrity, and community. But what she needed was proof: systems, structure, and measurable growth. Her vision for Luminary Cleaning Services was never just about cleaning spaces; it was about creating opportunities for Nashville residents and modeling what good business looks like when integrity leads the way.
From Small Town Fields to Strong Foundations
Brandon Mason’s construction roots go back to his family’s Kentucky farm, where he learned discipline and labor early. Surrounded by relatives in residential construction, he developed a strong foundation in materials, timelines, and accountability. That hands-on experience led him to earn a Construction Management degree from Western Kentucky University and manage large commercial and infrastructure projects, ranging from $5 million to over $500 million.
In 2019, Brandon launched BCMason Group, focused on industrial and infrastructure projects. While the firm gained a reputation for performance, operational complexity increased with contracts, from estimating and financial controls to project tracking and client communication.
