Our team

Better service. Complete solutions. Real people. That’s what sets us apart.

Charles
Solution Specialist

We are way more than simply moving part numbers.

Rozanna
Sales Associate

With Terabit it’s not about price. It’s about balancing clients’ needs with how much they can afford and guiding them to the solution.

Charles
Solution Specialist

It still has that new card smell.

Joe
Marketing Manager

Nothing feels better than being the hero who can ship a piece of gear the same day and keep a network running.

Daniel
Account Executive

Used does not mean less capable. As soon as gear is plugged in it becomes “used”, much like a brand new car driving off the lot.

Brian
General Manager

If you’re happy, we’re happy. If not, call us and we’ll make it right.

Raul
Senior Sales Associate

When the fans kick on 100% and traffic is flowing through the ports, I get a kind of rush.
