Liberty Language Services was founded to provide the highest quality language services at affordable prices. Liberty achieves these goals through comprehensive training and testing of interpreters, and by utilizing the latest technology in the field to deploy those resources effectively.
We are honored to be a leading steward of this industry and as such, our promise is to continuously develop and improve upon our program and services. We do this to better our company and raise the bar of excellence for the entire industry.
Our industry provides us with a unique opportunity to contribute to our community by facilitating communication between two parties that wouldn’t understand each other without bridging that communication gap. Liberty is proud to be an organization performing services that offer direct benefits to our society.
We believe in the promise of freedom and equality embodied by the Constitution of the United States of America; we understand that this is a nation of immigrants and we believe immigrants continue to build this nation’s future. That is why we are proud to work with talented, professional multilinguals, from all backgrounds, who have a passion for bridging communication with their language and culture skills.
We know that discrimination is a vile scourge that plagues most countries on Earth in one form or another. Only through mutual understanding can we overcome these societal challenges. Interpreters and translators play a critical role in erasing misunderstanding. The better trained and credentialed interpreters and translators are, the more effectively we can bridge that gap. Clear and accurate interpretation and translation are a critical need in every corner of our world.
We hope you join us in this effort in thought and spirit, to nurture an environment of acceptance, peace, and love for all our neighbors.
