Our Origin

Kos Partners takes its name from the Greek island of Kos, birthplace of Hippocrates and home to the Asclepeion, one of the earliest healing centers in the world. In antiquity, Kos was a place where medicine, philosophy, and environment were inseparable. Healing was understood as a holistic process, shaped by architecture, landscape, and the sensory experience of place.

In the same way Kos once redefined healing as an integrated process, we believe today’s real estate must redefine development as an integrated practice—balancing financial discipline with environments that restore and endure.

Founded by a Greek-American developer, Kos Partners draws inspiration from this legacy to shape a new model of real estate development. Just as the Asclepeion combined science, nature, and architecture, Kos Partners believes that the built environment should integrate wellness and sustainability at its foundation. This approach to development is not about amenities or trends, but about creating places that are resilient, regenerative, and elevate quality of life.

Company Vision

Research shows that wellness and sustainability must be built into both the financial model and the design ethos of every project.

Kos Partners is building a forward-looking model of real estate development—one where financial rigor and design excellence work together, and where wellness and sustainability are embedded at the foundation of every project. Each development is conceived as an environment that engages the senses—through light, acoustics, materiality, and atmosphere—shaping how people live and experience place every day.

It is no longer enough to say a project is adding wellness or sustainability. Research shows that these facets must be built directly into the financial model and the design ethos of each development, where they clearly and significantly impact both financial returns and human health and well-being.

We achieve this by combining market research and foresight with partnerships that place us ahead of the curve. At the core of every project is a world-class team of architects, designers, and industry leaders in wellness and sustainability. Their expertise ensures that our projects deliver both resilient performance and lasting revenue.

Leadership

Kos Partners was founded by Katerina Gregoriou, a real estate developer with a background in architecture and engineering. With academic training in architecture and real estate development at Columbia University and mechanical engineering at Stanford University, Katerina brings an interdisciplinary perspective that bridges financial discipline with design insight.

Prior to establishing Kos Partners, Katerina led the origination and design development of complex mixed-use and hospitality projects in New York City and Europe. This experience informs the firm’s commitment to pairing institutional performance with the creation of environments that enhance quality of life.


Looking Forward

Kos Partners is actively advancing its first flagship project in New York City while evaluating opportunities in a select pipeline of sites across urban markets. Each project is chosen with discipline—iconic locations where our philosophy of integrating wellness, sustainability, and design excellence can translate into both strong financial performance and lasting impact.

Our future growth is measured and deliberate: securing exceptional sites, shaping them alongside world-class sustainability and design partners, and delivering projects that define the next generation of real estate development.
