Professional testing provider PSI Services of Burbank has leased space in Glendale for its new corporate headquarters, according to commercial real estate firm Avison Young.

PSI has signed an 11-year deal to take nearly 23,600 square feet at 611 N. Brand Blvd. in the Glendale Center, said Avison Young. The Class A, 14-story tower totals about 399,000 square feet and PSI will occupy the full 10th floor, which has recently been renovated. The property has visibility from the 134 freeway and is close to retail and restaurants in the local main business area.

Jacob Bobek, a principal with Avison Young who brokered the deal on behalf of PSI, said PSI has outgrown the 17,300 square feet it currently occupies at 2950 N. Hollywood Way. Jones Lang LaSalle Inc. represented the building owner, LNR Partners Inc., according to Avison Young.

PSI provides licensing and certification tests, managerial assessments and pre-hire employment selection to corporations, federal and state government agencies, professional associations and certifying bodies.

In January, the company announced it bought Software Secure Inc., a testing firm for schools and higher education, while in December, PSI said it acquired Computer Assisted Testing Services, a testing services firm focused on the aviation industry. PSI’s clients include national retailer Target Corp., Department of Homeland Security and the U.S. Postal Service.
