Colliers Strengthens Tri-State Leadership with Strategic Hire from Mohr Partners

Colliers has made a significant addition to its tri-state regional operations with the appointment of Corey Horowitz as senior vice president. The seasoned office leasing professional, who previously served at Mohr Partners, officially joined the firm earlier this month and will focus on growing Colliers' office leasing division while providing strategic advisory services to clients navigating today's complex commercial real estate environment.

The hire represents Colliers' ongoing commitment to strengthening its presence in the New York metropolitan area, one of the most competitive commercial real estate markets in the country. Horowitz's extensive background in tenant representation and landlord services positions him well to address the evolving needs of occupiers and property owners alike.

Key Details

Horowitz assumes his new responsibilities immediately, reporting to regional leadership within Colliers' tri-state operation. His primary mandate includes:

• Business Development: Identifying and securing new office leasing opportunities across the region
• Client Advisory: Providing strategic counsel to corporate occupiers on workplace strategy and lease negotiations
• Team Expansion: Supporting the growth of Colliers' office leasing practice through recruitment and mentorship

The appointment comes at a time when many institutional real estate firms are repositioning their service offerings to address post-pandemic workplace dynamics and shifting tenant demands.

Market Impact

This strategic hire reflects broader industry trends as major brokerages compete for experienced professionals capable of navigating the current office market uncertainty. With vacancy rates elevated in many submarkets and tenants reassessing their space requirements, firms like Colliers are investing in talent that can deliver differentiated value to clients.

Horowitz's transition from Mohr Partners to Colliers also highlights the ongoing war for top-producing brokers and the premium placed on professionals with established client relationships. For CRE professionals, this appointment signals that despite headwinds in the office sector, leading firms remain committed to building out their capabilities—and that experienced leasing specialists continue to be in demand.

According to Commercial Observer, Horowitz will be instrumental in expanding the firm's office leasing footprint throughout the tri-state area, a region that remains a critical battleground for national brokerage firms seeking market share.

For tenants and landlords operating in the region, the addition of another seasoned professional to Colliers' roster may translate to more robust advisory options and increased competition among brokerages vying for assignments—potentially creating better outcomes for clients in an increasingly tenant-favorable market.

How to Measure the Hire

The appointment becomes a market signal when it produces identifiable assignments, team additions, or new client relationships. Horowitz's office experience may help Colliers compete across the tri-state region, but a biography alone cannot establish leasing momentum.

Clients should watch which submarkets, tenant sizes, and building classes receive the most attention under the expanded leadership. Landlords and occupiers should also compare the actual deal team, conflicts, and local track record—not only the brokerage brand. Those practical results will show whether the hire expands Colliers' capabilities or mainly reorganizes existing coverage.
