About us
At MPI, we believe exceptional property management is the foundation of a well-performing building. For over fifty years, we have partnered with owners of premier commercial office properties across Manhattan and the greater New York metropolitan area — protecting asset value, optimizing operations, and delivering the kind of tenant experience that drives long-term occupancy.

Every discipline works in concert, giving owners a single accountable team and tenants a seamless experience. We measure our success by the buildings we manage and the relationships we sustain.
