There are several reasons why Fullerton is considered a great city for Korean residents. The first is the educational environment.

Troy High School and Sunny Hills High School are among the top public high schools in California, making them the primary reason Korean parents choose Fullerton for their children's education.

Both schools offer a wealth of AP courses and have high college admission rates, providing an ideal environment for Korean families who prioritize college entrance exams. With CSUF located in the city, the path to college for children is naturally connected.

The second reason is the accessibility to Korean community infrastructure. While there are some Korean shops and churches in downtown Fullerton, the largest concentration of Korean businesses in Orange County, including Garden Grove, Buena Park, and La Habra, is just a 15 to 30-minute drive away.

Major Korean markets like H Mart, Hanam Chain, and Zion Market are also nearby, and there are Korean churches (such as Fullerton Presbyterian Church, Grace Ministries International, and Grace River Korean UMC) in downtown Fullerton, making it easy to maintain one's faith. The professional Korean community, including Korean-speaking doctors, lawyers, accountants, and real estate agents, is also widely distributed in the area.

The third reason is the geographical location. Fullerton is situated on the border of LA County and Orange County, placing it within reasonable distances to downtown LA (about 30 miles), Koreatown (about 30 miles), Disneyland (about 8 miles), and the Orange County coast (about 20 to 30 miles).

Using Metrolink, commuting to downtown LA is possible without a car, and commuting to major employment centers within Orange County is relatively convenient. The cost of living is lower than in premium areas of Orange County like Irvine or Newport Beach, while maintaining similar levels of educational quality and safety, which is attractive to Korean families.

The fourth reason is the weather and living environment. Thanks to Southern California's mild climate, outdoor activities are possible year-round, and there are well-equipped spaces for walking and exercising, such as Craig Park, Hillcrest Park, and the Santa Ana River Trail.

The vibrant restaurant and café culture in downtown Fullerton, along with a young and diverse population centered around CSUF, also enriches life in the area. The presence of first-generation, 1.5-generation, and second-generation Korean families has naturally formed a community across generations, making Fullerton a suitable place for Korean families.
