We would like to extend our heartfelt gratitude the customers, supporters and staff who contributed in so many ways to Professional Interpreter Exchange’s success over the past 15 years. It has been an amazing odyssey since PIE was launched as a fledgling sign language interpreting agency in 1993. We have grown from a modest beginning to be the premier provider of sign and foreign language interpretation in the Maryland, Washington, DC and Northern Virginia region. Today, PIE has a solid core of experienced staff interpreters, more than 120 freelance interpreters and more than 75 foreign language interpreters who provide services in the government, medical, legal, community, and educational sectors.
