InterpretAmerica, LLC was established in 2009 to provide a national and international forum for the interpreting profession. Our mission is to help raise the profile of interpreting. At InterpretAmerica, we feel the time is ripe for our field to unite around its similarities. Our goal is to provide an open and ongoing forum where key players from all branches of interpreting can gather and foster greater connection among its many sectors. Through conferences, webinars, virtual events, blogs, public speaking, publications, and other activities, we work to bring together the community, conference, legal, medical, military, civilian conflict zone, and sign language interpreting sectors, as well as educators, end users, buyers, vendors, technology designers and innovators in the interpreting field. InterpretAmerica seeks to elevate the profile and reach of the interpreting industry to the benefit of all.

The time has come for interpreters to step out of their background roles as seamless facilitators of communication, and into a place that allows our contributions to society, democracy, diplomacy, and history to be fully recognized; into a place where we can come together, be counted, and guide our craft. At InterpretAmerica, our efforts are focused on innovative and effective ways to support this vision.

We invite you to explore our website, review our publications, learn about upcoming events and contribute to ongoing discussions.
