SBA's Women-Owned Business Program was designed to promote the growth of woman-owned businesses through programs that (a) address business training and technical assistance, and (b) provide access to credit and capital, federal contracts, and international trade opportunities.

SBA's Office of Women's Ownership (OWBO) is at the forefront of helping women start and build successful businesses. You can learn more about them on the SBA web site at: http://www.sba.gov/ed/wbo/index.html

SBA also provides assistance through the Online Women's Business Center at http://www.onlinewbc.gov
