Chantal Kiener enjoys discovering little known artists. She has exhibited works such as the French artists Louis-Nicolas Cabat, Henry Cros, Georges Dorignac, as well as Armand Paulis (Belgian), and Florence Este (American). She selects works for their quality, originality, power, and poetry.

By appointment, Chantal Kiener presents paintings, drawings, and sculpture from the 19th and early 20th centuries, particularly preparatory studies, with a particular fondness for landscape studies executed en plein air from the late 18th century and the early 19th century.

Founding member of the Salon du Dessin, where she exhibited over many years, she took part in the creation of the 2017 Fine Arts Paris Salon and has exhibited regularly at the Quartier Art Drouot (QAD) since 2024.

At the 2018 Fine Arts Paris Salon, Chantal Kiener exhibited a collection of landscape studies (oil on paper) by Johann Jakob Frey (1813–1865) and, in March 2022, a collection of drawings and oil sketches executed between 1837 and 1852 by Louis-Nicolas Cabat (1812–1893). She contributed to the rediscovery of the work of the artist Henry Cros (1840–1907), mounting a monographic exhibition in 2017 of previously unpublished documents, sculptures, drawings and paintings, many of which were acquired by French and international museums.

As a lover of classical music, Chantal Kiener combines art and music by offering a selection of opera sets based on her discoveries.
