Whittier, located in the southeastern region of Los Angeles County, is a historic and culturally rich city known for its strong community roots, picturesque neighborhoods, and enduring commitment to education and civic pride. With a population of approximately 85,000, Whittier seamlessly blends small-town charm with metropolitan accessibility, making it one of the most desirable and livable cities in the Gateway Cities region of Southern California.
Founded in the late 19th century by Quaker settlers, Whittier was named after poet and abolitionist John Greenleaf Whittier, whose values of education, equity, and civic engagement continue to echo in the city’s identity. Whittier’s early years were marked by agriculture, particularly citrus groves, but it quickly evolved into a regional hub of education and commerce. Much of the city’s historical architecture remains preserved, lending a timeless character to its commercial and residential districts.
At the cultural and economic heart of the city is Uptown Whittier, a walkable district featuring historic buildings, independent shops, sidewalk cafes, art galleries, and community events. Landmarks like the Whittier Village Cinemas, Shannon Center for the Performing Arts, and the restored Greenleaf Avenue streetscape reinforce Uptown’s reputation as a lively and pedestrian-friendly destination. Events such as the Uptown Whittier Art Stroll, Farmers Market, and Vintage Car Show bring together residents and visitors to celebrate the city's creative and communal spirit.
Whittier is also home to Whittier College, a private liberal arts institution founded in 1887 and known for its commitment to academic excellence, civic engagement, and diversity. The college contributes to the intellectual and cultural vitality of the city through public lectures, performing arts, and student-driven community initiatives. Adjacent to the college is the Shannon Center, which hosts concerts, theatrical productions, and cultural performances throughout the year.
The city places a strong emphasis on preserving its historical legacy. The Whittier Historical Society & Museum, located near the Civic Center, showcases artifacts, photographs, and exhibits chronicling the city’s Quaker origins, citrus era, and postwar development. The Pio Pico State Historic Park, located at the city’s western edge, preserves the 19th-century adobe home of Pío Pico, the last Mexican governor of California, and offers a rare glimpse into California’s rancho period.
Parks and green spaces are integral to Whittier’s quality of life. The scenic Hellman Park Trailhead and Turnbull Canyon in the Puente Hills Preserve provide panoramic views, hiking trails, and natural habitat, making them popular destinations for outdoor enthusiasts. Central Park, Palm Park, and Penn Park offer recreational facilities, picnic areas, community events, and youth sports leagues. The Whittier Greenway Trail, a repurposed rail corridor, serves as a safe and scenic route for joggers, walkers, and cyclists, connecting neighborhoods across the city.
Civic life is anchored at the Whittier City Hall and Whittwood Branch Library, both of which support robust community engagement. The city operates a full range of services and programs for youth, seniors, and families, including art classes, recreation leagues, public safety outreach, and seasonal celebrations like the Whittier Christmas Parade and Summer Concerts in the Park.
Whittier is also a retail and dining destination. The Whittwood Town Center, located on the city’s eastern side, offers a modern shopping experience with a mix of national retailers, restaurants, and service businesses. Meanwhile, the local dining scene—from family-owned Mexican and Italian eateries to coffee shops and wine bars—adds flavor and personality to each neighborhood.
Residential life in Whittier offers a wide variety of options, from Craftsman homes and Spanish Revival residences in historic districts like College Hills and Hadley-Greenleaf, to modern condominiums and family-friendly developments in East Whittier and Friendly Hills. The city’s neighborhoods are known for their cleanliness, walkability, and strong community associations.
Whittier’s strategic location—near the intersection of the I-605 and SR-60 freeways—provides easy access to Downtown Los Angeles, Orange County, and the Inland Empire. Despite its proximity to urban centers, Whittier retains a peaceful, suburban feel rooted in heritage, civic pride, and community cohesion.
Today, Whittier stands as a model of balanced urban development—where history and progress coexist, where neighborhoods thrive, and where culture, education, and civic life are woven into the fabric of daily living.
