"This collaboration reflects how aligned goals and the right operational partner can create real momentum. Our third party management program is built to seamlessly take on large-scale onboarding while maintaining a consistent focus on performance, service, and long-term value.” Herby Bowman, VP of Third Party Management for StorageMart and Manhattan Mini Storage.

"The Nagel and Burnam families have known each other since the early 1970s, when both were pioneers in the emerging self storage industry. As Metro and the Nagel family transition to an asset management and real estate investment platform, our partnership with StorageMart to outsource property management is a natural fit. StorageMart’s culture closely aligns with ours and provides the opportunity for Metro and its partners to leverage the operating scale and efficiencies of the world’s largest privately owned self storage company, with more than 300 locations. We are excited to launch this new partnership across the Nagel family’s wholly owned facilities and select Metro joint ventures.” Matthew Nagel, Chairman, Metro Storage LLC

As part of the StorageMart and Manhattan Mini Storage Third Party Management portfolio, these locations now benefit from industry-leading services including centralized call center support, dynamic revenue management programs, industry-leading operational systems, and strategic marketing programs tailored to local audiences.
