What is a credenza used for in a professional office?

A credenza is a low-profile storage unit (typically 30"–66" wide x 18"–20" deep x 29"–30" tall) placed against a wall behind or beside a desk. It provides additional surface workspace and enclosed storage via drawers and doors. Credenzas often include a combination of storage drawers, file drawers, and display space on top. They're standard in executive suites. OfficeFurniture2go.com has credenza options to match most desk lines — call 1-800-460-0858.
