More than a COURIER!

We deliver what our competitors only promise!


Here at ProEx, we are more than just a courier service. We measure our success not by the volume of deliveries we handle each day, but by the satisfaction of our customers. From individuals to Fortune 500 companies, ask any one of our clients what makes ProEx the best, and they will all tell you the same thing: we consistently deliver prompt and reliable service. We really do deliver what our competitors only promise. So don’t settle for less, call ProEx Delivery today!



It is not our goal to be the biggest courier service in Washington, D.C...only the BEST. Unlike many of our competitors, we will not take on more work than we can handle, and honesty and integrity are vital components of our business



The legalization of a document for use overseas can be a confusing and complicated process. We have over twenty years of experience processing apostille certifications and embassy legalizations.



Whether you simply need a few boxes moved, or an entire office complete with equipment and furniture, ProEx Delivery is a trustworthy and reliable source to turn to for assistance. Find out more about how we can help make your transition as smooth and painless as possible.



In addition to the standard courier and document authentication services we offer, ProEx Delivery Corporation is proud to offer our clients specialized services. 



With over sixty years of combined courier service experience, ProEx has been servicing Washington, D.C. and surrounding areas with dependable delivery and document authentication services at the highest level of professionalism and satisfaction. At ProEx, our focus is quality over quantity, and we will never accept more work than we can handle for the sake of being able to claim that we handle over 2,000 deliveries per day. No matter your needs, you can trust us to handle your deliveries promptly and efficiently, enabling you to focus on your more urgent matters.



If ProEx does not deliver by your deadline, your order is free*. It's that simple.

Now, we know you have heard this many times before, only to receive fees on late deliveries on your next monthly invoice. You end up spending long periods of time on the phone, only to get nowhere, right?

We deliver what our competitors will only promise you.

This principle has been practiced by our company since it was founded in 1990 by William Barnes. After going through the same tribulations that you probably have experienced with other local and worldwide delivery services, Bill realized that the Washington, D.C. area was truly lacking a reliable and trustworthy delivery service

"Thanks so much for taking care of this item in an professional and expeditious manner.  I truly appreciate you, and your diligence. Cindy was great to work with, and it has been a pleasant experience working with you guys during this step in the legalization process. Providing a quality product or service, and executing its delivery with highly evolved interpersonal skills while doing so, is not always the simplest of tasks. Yet you guys pull it off well, and make it look easy!"

- Richard Wiley
