Personal services


Healthcare has been at the heart of Philippe Austruy’s activities for 40 years. He founded the first medical and surgical hospitalization group in France, giving this sector the industrial and professional dimension it has today. He then took part in the restructuring of the retirement home sector. After Medidep and the first IPO in this sector, he developed this activity in Belgium and Luxembourg.

Driven essentially by the well-being of human beings, the SIS Group continues to endeavour for dependency care, from the youngest to the oldest, in France, Belgium and Luxembourg: crèche, addiction care centres, accommodation facilities, etc.

The Group has exported its services to other countries: Portugal, Brazil, Greece, Colombia, Mexico, etc.

Real estate


The capacity to manage a real estate portfolio is one of the keys to success in healthcare. This ability has consequently developed naturally within the SIS Group, focusing primarily on the management of clinics, retirement homes, retail premises, creches and home service agencies.

The SIS Group created the first French real estate company dedicated entirely to the dependency and early childhood care by grouping its ad hoc real estate assets in Foncière Siscare. Siscare held 82 such assets at the end of 2019.

The creation of Foncière Siscare has made it possible to optimize the human, technical and financial resources dedicated to the management of the group’s asset, the number of which has grown substantially, apace with the fast-growing dependency and small childhood care markets in France and Europe.

An activity of promotion, property sales and rentals of furnished accommodation has followed in the footsteps of these initial experiences. SIS Immo, as this real estate segment is known, owns residential and office premises in France, Portugal, Spain, Brazil and Greece.

A new coliving housing project was born in 2020 in Brussels :


The value of the SIS Group’s real estate assets in 2019 was estimated at more than €700 million.



Art of living


For a group interested in people's well-being, the art of living is a central concern. Within SIS, the art of living is expressed through a wine-growing business, catering and contemporary art collections. SIS has reawakened several beautiful dormant wine-growing estates. A concern for quality and respect for the terroir and nature have revived them and made them flourish. After three such projects in France, the Group is developing in the Douro Valley in Portugal and in Italy. Quinta da Côrte is launching a wine-tourism business. The Group has recently acquired La Bernarde, a vineyard near the famous Commanderie de Peyrassol. This estate was acquired with the aim of developing organic wine production. You can find the natural produce of these vineyards in simple, authentic and lively restaurants, currently in Paris, Saint-Tropez and Brussels. The art of living theme continues in a park of more than 70 monumental sculptures in the Domaine de Peyrassol and an exhibition centre in Brussels. New works are regularly added in the sculpture park.

Philippe Austruy


At the helm of SIS, a family-owned holding company for all of his shareholdings and businesses, Philippe Austruy is a pioneering entrepreneur and business leader in the private health and long-term care industry.

Over the past forty years he has contributed to the present structure of the French health landscape by participating in the founding of private hospital-care groups, more specifically surgical clinics (medicine, surgery and obstetrics).

Philippe Austruy then committed to and reorganised the long-term care sector with the development of private care homes for the elderly and the design of a new format, post-acute care and rehabilitation centres, which have helped to contain hospital health expenditure. Finally, he supplemented the range of services dedicated to addiction by developing a home-care services business.

As a genuine pioneer of new horizons, he is also participating in the opening-up to private players in the childcare sector, thereby ramping up the supply of nursery places accessible to young parents. Based on the establishment of public/private partnerships, the founding and management of Early Childhood Education and Care (ECEC) establishments offers turnkey solutions to hospitals and their employees as well as to local authorities and their constituents.

Finally, as a wine lover with a passion for the finest terroirs, Philippe Austruy has amassed a superb collection of vineyards that over the years he has rehabilitated with a focus on excellence: The Commanderie de Peyrassol and La Bernarde in Provence, Château Malescasse in the Haut Médoc, Quinta Da Côrte in the Douro Valley in Portugal and Tenuta Casenuove in the heart of Tuscany in Italy.

Born in 1949, Philippe Austruy is a graduate of the Paris Institute of Political Studies and has a doctorate in economics. An acknowledged expert in the health sector, he has authored a number of articles and books and held responsibilities within the Fédération Intersyndicale des Établissements d'Hospitalisation Privés (Private Hospital Care Federation - FIEHP), the private oncology syndicate and other sectoral organisations. He also founded the club of companies listed on the Nouveau Marché equity market which promoted growth companies.
