A Rich History

Belmont Associates began as The Belmont Paper Box Company on Belmont Street in Greenpoint, Brooklyn. Founded by Great-Grandfather Aaron Rosinsky in 1908, the company’s beginnings were rooted in the production of corrugated paper boxes and has since evolved into a robust and highly esteemed commercial real estate investment firm. Since Aaron Rosinsky’s founding of the company, each generation of Rosinsky men has acted as sole principal and has been actively involved in operations and asset management.
