about US
Columbia Management Group is a family-run, in-house management company overseeing both self storage and multifamily housing assets.
Our self-storage platform, Columbia Self Storage, has been operating since 2012 with locations across New Jersey, New York, Pennsylvania, and Arizona. In 2017, we expanded into multifamily housing with the acquisition of a luxury 55+ community, forming Columbia Realty Group.
Built on long-term relationships and operational consistency, we manage each property with the same care and accountability we expect for our own family’s investments.
We’re always interested in new opportunities and welcome conversations with owners considering the sale of a property or portfolio.
