A year after its founding, the gallery expanded next door to 7313 Santa Monica Boulevard. Formerly the famous Actor's Circle Theatre, the historic theater was transformed into an additional 1,200-square-foot exhibition space crowned by its iconic marquee. With the addition of the larger space, the gallery was able to present eight to twelve exhibitions a year, innately developing its programming to artists based in Los Angeles, including: Louise Bonnet, Celeste Dupuy-Spencer, Jake Longstreth, Polly Borland, Alessandro Pessoli, Jansson Stegner and Jon Pylypchuk. The artist roster continues to develop, and although there is a clear focus on German and Los Angeles-based artists, the gallery is extremely proud to be representing international artists Peter Bonde and Tomasz Kowalski, among others.

Notwithstanding the international expansion, Nino Mier Gallery continues to devote itself to Los Angeles as a home-base. In 2018, the gallery announced the opening of a new 5,000-square-foot gallery at 7277 Santa Monica Boulevard in an iconic ivy-covered bow and truss landmark located directly across the street from the existing galleries. Retaining the spaces to expand its program across the three neighboring buildings, Nino Mier Gallery now occupies the entire north side of the cross street in the heart of the West Hollywood, at the center of a constellation of new and established galleries that have shaped the art scene over the last few decades. The space was inaugurated with a major solo exhibition by Celeste Dupuy-Spencer.

Nino Mier Gallery currently represents over twenty living artists, as well as two major artist's estates, including the Estate of William N. Copley alongside Kasmin Gallery, New York, and the Estate of Georg Karl Pfahler, of which the gallery is the sole US-representative. This summer, the gallery will celebrate its five-year anniversary with a group exhibition bringing together the entire roster of artists for the first time.

In 2022, Nino Mier Gallery opened a space in Glassell Park in order to connect with audiences in eastern Los Angeles. Situated at 2700 W Ave 34, Los Angeles, 90065, the 1,500-square-foot gallery also serves as a home base for our many artists whose studios are located in the area. The gallery’s programming is centered around focused, conceptually-driven projects, and was inaugurated with an installation by Kareem-Anthony Ferreira.
