The best interpreters and translators

We provide the best interpreters and translators for each project. Our interpreters and translators possess qualifications such as American Translators Association (ATA) Certification, Court Interpreting Certification, degrees in interpreting and translation, advanced degrees, rich knowledge and experience, and customer service skills. Our interpreters clearly communicate with genuine tone, emphasis, and style to best enhance and strengthen relationships. Some are world-renowned and have interpreted for Fortune 500 companies, the US Department of State, and the United Nations. Our interpreters have interpreted for presidents and global leaders. We practice discretion and observe strict client confidentiality.

Our interpreters and translators possess industry-specific knowledge and experience in a wide variety of fields, including academia, administration, agriculture, banking, business, civil litigation, communication, diplomacy, distribution, education, environment, finance, government, immigration, insurance, internet security, investment, justice, law, law enforcement, legislation, leisure, manufacturing, medicine, pharmacy, pharmaceuticals, research, study, trade, and travel.

Interpreting services

Our precise interpreting services include conference, consecutive, court, simultaneous, Skype, telephone, over the phone, and video conference interpreting. For example, our conference interpreters have provided simultaneous interpreting services at annual, diplomatic, environmental, and international conferences. They have performed consecutive interpreting for attorney-to-client communication, business negotiations, company meetings, executive education and training, factory visits, inspections, interviews, investment research interviews, manufacturing facility inspections, medical interviews, meetings, negotiations, tours, shareholder meetings, and visits.

Translation services

We provide pristine translation services. Our translators have translated agreements, background checks, birth certificates, contracts, employment verification, event planning, health insurance, immigration documents, instruction booklets, lease agreements, marriage certificates, patents, short-term studies, user manuals, vendor agreements, and website localization. Our translation services include quality control and proper formatting to create ready-to-publish documents.

Conference equipment

We provide simultaneous interpreting equipment and technical support for conference interpreting. We streamline simultaneous interpreting at meetings, events, and conferences with our team of interpreters and technician. The technician arrives 90 minutes to 2 hours in advance to set up the conference equipment. The audience members listen to their selected language with the provided headsets while a pair of interpreters simultaneously interpret in the booth. The mentally demanding task of conference interpreting requires interpreters to rotate every 20-30 minutes. Our simultaneous conference interpreting equipment includes booths, headsets, microphones, and transmitters.

Our Story

Chinese conference interpreter and translator Philip Rosen feels passionate about interpreting and translation across languages and cultures. He has 12 years of experience providing Mandarin Chinese to English interpreting and translation services for business, government, and nonprofit leaders. As an active linguist, he observes that low-quality translation loses ideas, damages connections, and disappoints all parties involved. Miscommunication wastes valuable time and energy. He decided to found a translation company run by the best interpreters and translators in Washington, DC, to solve these problems.

Interpreters and translators fully recognize that effective communication across languages and cultures depends on accuracy, precision, and clarity. Unlike our competitors, we focus on delivering the top quality interpreting and translation services possible for any language. We provide the best quality interpreting and translation services for all languages through our quality control process. Capital Linguists has expert interpreters and translators ready to take on new assignments for interpreting and translation in Washington, DC, and across the US, Canada, China, and Taiwan.

Our translation company focuses on delivering top-notch customer service. We seek to become a valuable resource to all of our clients based on their needs and requirements for each customized project. Former US Ambassador to China Clark T. Randt Jr. and others have endorsed our services. When our clients return for repeat business, we express our gratitude with a passion for high quality and fast response rate. We greatly appreciate referrals, recommendations, and reviews.

Chinese conference interpreter Philip Rosen delivered interpreting services for Zhang Ruimin, a world-renowned entrepreneur, founder of Haier Group, and one of the top 50 global management thinkers. Our interpreters’ passion for delivering high-quality interpreting services leads us to provide language support to global leaders. Of course, we consider each opportunity to contribute to the needs and requirements of these individuals and their organizations a great privilege.
