ABOUT

Our History

Letter Supplies is a janitorial supply company, founded by two childhood best friends, Michael Greenbaum and Eli Gross. Their combined understanding of Supply Market trends and their ability to forecast customers’ needs, led to an expanding business operation with personalized service to each of their clients.

Locations and Delivery

With two warehouses strategically situated in Brooklyn, NY and Fairfield, NJ, their fleet of trucks services the Tri-State area with speed unmatched in the industry. This is a direct result of their staff’s vast experience and expertise in the janitorial supply world. 

Our Facilities

They operate from their state-of-the-art 7,000 and 15,000 sq ft facilities, with targeted attention and precision to their customer’s needs and expectations. Today, Letter Supplies employs a staff of over 20 people.


           Expansive Cleaning Supplies Inventory

Our products range from janitorial equipment and professional cleaning supplies, cleaning chemicals, including restroom supplies, carpet cleaning products, floor cleaning supplies, commercial disinfectants, disinfectant spray cleaners, Pest control products, and ice melt compound & spreaders.

Stability is Key

Eli and Michael have put their heart and soul into building their company Letter Supplies. Throughout the years, it became clear that a solution was needed in the current volatile market to identify and ensure that products reached their customers with utmost certainty. Often that means stocking up on anticipated shortage items, and ensuring their price points remain constant.

Michael and Eli are proud that their childhood dreams have evolved into the opening and operating of a business that has become a major force in the janitorial industry.
