Christophe Dumoulin held the offices of deputy mayor and mayor of the municipality of Bagnes between 2005 and 2012. Born in 1970, he joined the family firm at the start of 2013 and he is now its managing director. He holds a Swiss Federal Trustee Certificate that he obtained at the IREF, in Yverdon, after three years of continuous training.

As mayor of Bagnes, he was successively in charge of the finance department and of the utilities department. He was Chairman of the Board of Sateldranse SA and Netplus SA (telecommunications) and of SOGESA, SEDRE SA and GECAL SA (energy). He was a director of the Board of TMR SA (transportation), Téléverbier SA (ski lifts) and Forces Motrices de Mauvoisin SA.

During his sixteen years of political life, Christophe Dumoulin participated intensely in the cultural life of Bagnes, notably as a member of the Board of the Verbier Festival. He still remains very committed to the associative life in the canton of Valais. He was treasurer of the Ski Montaineering World Championships of Verbier-Val de Bagnes in 2015 and he holds the same responsibility for the Chamber Orchestra of Valais. Finally, he is Chairman of the Tour des Combins.

Married with three sons, Christophe Dumoulin has a passion for cars. It is however not uncommon to encounter on the trails and routes of the valley, where he practices hiking and ski-touring. This regular training allows him to indulge, as an Epicurian, in another of his passions: wine.
