We are the only team specializing in rare diseases (Orphan Diseases) across neuroendocrinology, neurology, and neurometabolic disorders. Our unique consortium brings together renowned specialists who collaborate seamlessly while maintaining their independence. This innovative structure allows us to assemble a bespoke, cross-border treatment team for each patient - perfectly aligned with your individual medical needs.

As of July 2025 the Lazar| Seideman | Samaras clinical network for rare neuroendocrine disorders has officially relocated its headquarters from Athens to New York City. After many successful and fulfilling years in Athens – for which we are sincerely grateful – this move marks an exciting new chapter for our international presence. Importantly, this relocation of the headquarters does not affect the quality, accessibility, or continuity of care, particularly for patients within the European Union. All of our European colleagues who were previously based at our Athens headquarters remain fully active in clinical practice – continuing their work from new premises in Athens. They are not operating from the United States, but continue to serve patients locally and across the EU with the same commitment and expertise. We thank you for your continued trust.
