Meet the Team

Hamilton Sweeney

Founder

Hamilton Sweeney founded Stone Development in 2023 with a clear vision: to build a development firm rooted in Central Florida that approaches every project with the same level of rigor, intentionality, and hands-on involvement. With experience across both commercial and residential asset classes, Hamilton brings a well-rounded foundation to the firm's acquisitions, underwriting, and project execution.

Beyond the numbers, Hamilton is deeply involved in the physical side of development. From managing the bidding process to tracking construction budgets in real time, he stays close to every phase of a project to ensure costs stay in line and timelines hold. That ground-level involvement shapes how he approaches acquisitions, always evaluating deals with an eye toward what it actually takes to build and deliver them in the Central Florida market.

At the core of Stone Development is Hamilton's long-term commitment to building something lasting in the region he knows best. He is drawn to the entrepreneurial nature of real estate and is focused on developing the relationships, instincts, and track record that define a firm built to grow.

Mia Russo

VP of Operations and Interior Design

Mia Russo brings a rare combination of creative vision and operational precision to Stone Development, shaped by years of experience at a leading interior design firm where she worked on residential projects across the country. Exposure to diverse markets, architectural styles, and client expectations gave Mia a sophisticated eye for design and a deep understanding of what makes a home feel intentional from the moment you walk in the door.

Known for being exceptionally organized and detail-oriented, Mia approaches every engagement with a clear process and a sharp eye for staying ahead of design trends, ensuring that each home Stone Development delivers reflects a modern, curated aesthetic without ever feeling overdone. That owner-first perspective is woven into every decision she makes, from material selections to space planning, and it is central to the product Stone Development is building in Central Florida.
