On Site Companies: Certified Women Owned Business

There is a stereotype in our culture for “business owner.” Often times, the knee-jerk image in our head is of man. Culturally, this was certainly true for a very long time, but those times have been over for generations. On Site Companies is proud to be a Women Owned Business, certified by the Women’s Business Enterprise National Council (WBENC).

What is the WBENC?

The WBENC is the United States’ largest certifier of women-owned businesses. Founded in 1996 by four women in Texas, the WBENC officially launched in March of 1997 with eleven corporate members. One of the core missions of the WBENC is ensure women owned business enterprises participate in the global economy.

Today, there are more than 14,000 certified WBEs in the United States and more added constantly. There are also corporate and government members of the WBENC. The corporate members of the WBENC consist primarily of Fortune 500 companies and include in their ranks Coca-Cola, Apple, Microsoft, General Motors, and more.

Women Owned Business Certification

What does it mean to be a certified Women’s Business Enterprise? To be eligible for certification, a business must be at least 51% owned and controlled and operated by a woman. Businesses must also complete a certification process.  The process includes formal documentation and site visits by one of the WBENC’s regional partner organizations.

There are many benefits to being a certified WBE. The most obvious benefit to being a certified WBE is national recognition by thousands of major U.S. corporations and federal, state and local government entities. Many government contracts for projects require a percentage of the funding to go to WBEs whether as subcontractors or service providers on the project.

The Women of On Site

Today, On Site Companies is owned by Karen Holm (alongside her husband, co-founded, and co-owner, Dave) and Karen’s daughter, Molly is vice president of the company. Beyond that, a third of the company-wide leadership team consists of women. Outside of leadership, we have women working in every facet of our business.
