                                  PRESS RELEASE
                                  -------------

     ST. LOUIS (July 9, 2002) - Enterprise Financial Services Corp (OTCBB:EFSC)
announced today that Kevin C. Eichner, vice chairman of its board of directors,
will assume the post of president and chief executive officer, effective
immediately. Eichner succeeds Fred H. Eller, who will continue to serve on the
Enterprise Financial board and develop business opportunities for the company in
the Denver market.

     The move is part of a planned transition involving Eichner and Eller,
co-founders of the former Enterbank Holdings, Inc., in 1988. Shareholders
earlier this year approved a name change to better reflect the emerging family
of businesses at Enterprise.

     Eichner, formerly chief executive of St. Louis-based GenAmerica Financial
Corp. and Collaborative Strategies, Inc., has served as vice chairman of the
Enterprise board since 1988 and will continue in that position.

     Enterprise Financial operates commercial banking and wealth management
businesses in metropolitan St. Louis and Kansas City, Mo. and southeastern
Kansas, with a primary focus on serving the needs of privately held businesses
and their owners.
