About Us

Service that is Above the Rest

Our stellar reputation, friendly and bilingual staff, 35+ years of experience, personal approach to resolving issues, uninterrupted availability, willingness to explore all options to deliver requested service for our clients while maintaining integrity and cultural sensitivity, meticulous attention to every detail, reasonable and competitive pricing, and incomparable customer service are the attributes that elevate our job performance and set the agency apart.

Among our associates are court-certified and registered interpreters, accredited and qualified freelance translators with a proven track record in respective language pairs and subject specialties (most are members of the American Translators Association and other professional chapters).

This multifaceted approach coupled with over three decades of experience in language translation, project management, incomparable customer service and genuine love for what we do, gives Advanced Translation Services the distinct edge and that elusive balance of creative precision.

Since being founded in 1986, Advanced Translation Services quickly grew into an easily accessible language service agency located in the bustling Fairfax District, just blocks from The Grove and a short distance away from Hollywood and downtown to the east, and Century City, Beverly Hills and Santa Monica to the west.


Family-Based Immigration

We provide assistance with interpreting and helping to file paperwork for Americans who wish to bring their spouses, children, parents and siblings to the U.S., and eligible green card holders seeking to reunite with their immediate family members (spouses, parents, and unmarried children).
