Leadership includes Harvey Mendelsohn (CEO), Catherine Mendelsohn (COO), Micheline Mendelsohn Luhn (Deputy CEO), and Chef Spike Mendelsohn (Executive Consultant), supported by a small team including a Financial Controller, Director of Business Development, and concept-level operators. In-country representative offices are maintained in Cairo, Athens, Amman, and Dubai to support international expansion.
