Louis Stern Fine Arts, located in West Hollywood’s Design District, focuses on Mid-Century West Coast Geometric Abstraction and represents the artists who defined and epitomized the California Hard Edge movement: Lorser Feitelson, Helen Lundeberg, and Karl Benjamin. The gallery also holds works by other influential Mid-Century abstract painters including John McLaughlin, Frederick Hammersley, and Roger Kuntz.

Other estates represented by Louis Stern Fine Arts include Mark Feldstein, James Jarvaise, Ynez Johnston, Matsumi Kanemitsu, Alfredo Ramos Martínez, Mimi Chen Ting, Doug Ohlson, and Frederick Wight.

A stable of contemporary artists, including Gabriele Evertz, Heather Hutchison, Mokha Laget, Mark Leonard, James Little, and Richard Wilson, along with sculptors Knopp Ferro and Cecilia Miguez and photographers Magali Nougarède and Jean-François Spricigo, supplements the gallery's historic program.

In addition to its exhibition program, Louis Stern Fine Arts has had a long and successful involvement in the secondary market, with a special concentration in Impressionist, Post-Impressionist, Modern and Latin American art. As director of The Alfredo Ramos Martínez Research Project, Stern oversees the development of the catalogue raisonné for the artist.
