After a formation at the Royal Academy of Fine Arts in Antwerp - Belgium, Catherine Ruszniewski created a painted wooden toys company in Belgium while still painting, using lithography, and drawing to express herself.
She came back in France in 1996 and exhibited her paintings again at the Paris-Prague gallery of Jana Boxberger in Nant, near Millau.
Eventually, after settling on the Bay of Arcachon in South-West France in 1998, she devoted herself mostly to canvas paintings. She exhibits her works regularly in different regional galleries, including l'Atelier at La Teste de Buch.
Today she divides her time between her art and transmitting it to others in individual or group courses.
