Pierrick HAAN

Pierrick Haan is an engineer by training, specialized in biological and medical engineering. In 1982, then completing an internship in a unit at Inserm, he created a start-up called SEFAM (Société d'Étude et Fabrication d'Appareillage Médical), focusing on the use of medical technologies.

On the advice of Dr Jean Krieger (neurologist at the Strasbourg State Hospitals) and Prof. Paul Sadoul (head of the respiratory department at Nancy University Hospital, Inserm Unit Director, and founding President of Antadir), in 1984 SEFAM began developing a continuous positive airway pressure device to treat the still little-known syndrome of sleep apnoea. Equipment to diagnose and treat respiratory disorders then became the core of SEFAM’s business.

In 1993, Pierrick Haan bought Dupont Medical which he grew to a market leader for assistive technologies for independent living.

In 1994, Haan sold SEFAM to the American group Puritan Bennett, of which he had become a shareholder.

In 2010, he bought SEFAM back from the American company Covidien. Haan had a big idea: to bring SEFAM, a historical French brand with unique experience and expertise, back to life and to make it the partner of choice for doctors, home healthcare providers and patients with Obstructive Sleep Apnea (OSA).

Pierrick Haan’s strategy is based on innovation, developed in close collaboration with our Medical Advisory Board he has assembled and which is composed of leading doctors with expertise in the treatment and management of respiratory sleep disorders.
