First Business Celebrates 15 Year Anniversary

MADISON, April 14, 2005 - This month, First Business Bank and First Business Financial Services are celebrating 15 years of serving the local business community. First Business Bank of Madison opened its doors on April 1, 1990 as one of the first Business Banks in the Midwest - only one of a handful in the country at that time. First Business Bank was the first to introduce business-focused services such as no-cost courier pick up, sweep accounts, and indexed money market accounts to local businesses and business executives. First Business has expanded over the past 15 years. In 1995, First Business Capital Corp., an asset-based lending company, was formed. First Business Leasing was formed in 1998, and First Business Trust & Investments in 2001. First Business Bank - Milwaukee opened in Brookfield in 2000. In 2004, First Business Financial Services, the parent company of the First Business family of companies, announced its intentions to go public. "When we founded First Business, we sought to provide a higher level of personal service. To do this we built a corporate culture based on respect, open communications, and a strong work ethic. We wanted clients and staff to be proud to tell people they bank at or work at First Business," stated Jerry Smith. "I’m pleased to say, this is still our foundation today." Smith was one of the original founders of First Business Bank, served as First Business Bank President and CEO from 1990 to 1999, and is currently the Chief Executive Officer of First Business Financial Services.
