About our VOSB Designation


Veteran Owned Small Business (VOSB) is a company diversity registration designated under the Veteran Benefits, Health Care, and Information Technology Act of 2006 (Public Law 109-461). Registration ensures that companies qualify for preferential procurement for federal contracts if they are owned and controlled by Veterans.

This certification is non-industry specific and requires that the firm meets the small business requirements established by the Small Business Administration (SBA). Additionally, it requires that the company is at least 51% owned, operated and controlled by a veteran.
