GREEK MARBLE ASSOCIATION
John Papagiannoulis Bros
An important milestone
A defining shift for John Papagiannoulis Bros was moving from a purely production-driven company to one positioned closer to sourcing
marble—through our own quarries and select partnerships—but also to end projects. By aligning our operations from the birth of the
marble we work with to its final destination, we bridge the space between material and architects and partners worldwide. This transition
has shaped our north star: to understand marble and place it meaningfully within contemporary architecture and design.
Philosophy
We approach marble as something alive, aiming each time to match it with the right project. We consider origin, performance, and use, and guide our partners towards the best choice for them. We always focus on understanding both the stone and the context in which it will exist, building relationships based on trust and long-term reliability.
Strengths
Our company stands out through its long-standing international presence and experience across all segments of the natural stone sector. Our people have a combined experience of over 200 years in all operations: from quarrying and processing to selection and specifying. With our own quarries in Thassos and Volakas and a factory in Athens, alongside a wider network of premium stones and specialized producers worldwide, we offer both range and control. Our strength lies in understanding each project and helping our partners make the right material decisions with confidence.
What we stand for
Quality & Trust
The Greek Marble Ouzeri
Greek Marble Ouzeri is an opportunity for us to share what marble means in our lives. It is a material to admire, but also to understand, observe, and make part of everyday life. We invite guests to experience Greek Marble in small, intimate moments that ground us and bring us together: around food, a drink, conversations with friends, a moment to rest. And hopefully inspire them to use this versatile material in their next projects as well.
