Stéphanie Peyrissac was born in 1970 in Neuilly sur Seine.

Trained at the Institute of Art and Archaeology of Paris IV Sorbonne, she holds a Master II in research and is the author of a monograph and the catalogue raisonné of the painter and sculptor Jean Peyrissac (1895 – 1974). After a year spent as assistant to Christophe Durand-Ruel in the contemporary art department of the study of the auctioneer Francis Briest, Stéphanie Peyrissac returned in 1992 as a temporary employee to the Contemporary Galleries of the Centre Georges Pompidou, Museum of Modern Art, where she worked on the organization of the various exhibitions with the curator Jean de Loisy. She is notably an author of the catalogue of the important exhibition "Hors Limites, l'Art et la vie 1952 – 1994" in 1994. She then worked on an exhibition project in Europe "Song Lines Europe 97-98" with Jean de Loisy and then spent a year as a documentalist at the Fonds Régional d'art contemporain Centre in Orléans. In the 2000s, she began working for the dealer Luc Bellier for whom she inventoried the family collection and collaborated on the various exhibitions in his gallery on rue de l'Elysée: Edouard Vuillard "le silence me garde", Edouard Munch, Jacques-Henri Lartigue "l'empreinte du bonheur", Pablo Picasso "l'oeil, la main, le génie".

For the past twenty years, she has chosen to work in a private practice in order to pursue her work as an art history researcher. As part of this activity, she spent five years finding the paintings of a family whose property had been looted during the Second World War. She carries out research and expert appraisal work on request. She also searches for paintings for seasoned collectors or helps build collections.
