The Native Sons of the Golden West (NSGW) Arrowhead Parlor #110 is a fraternal organization dedicated to preserving California's history and culture.

The NSGW documents and maintains historic buildings, places, and monuments, places historical landmark plaques, and sponsors scholarships for high school students who are related to members. They serve as the official sponsoring agent for the Cleft Palate Program, observe California's admission to the Union annually, and have contributed to the formation of California State Parks.

**Membership:** The NSGW is open to people born in the USA who are at least 18 years old. Interested individuals can apply for membership by contacting them at Westmarkx1@gmail.com.

Established in San Bernardino in 1887, the Arrowhead Parlor was located for many decades in Chocolate Palace Café, the same site as the building today.

On October 14, 2023, the Arrowhead Parlor dedicated The Enterprise Building as a Historic Site.
