Michael L. O'Reilly

Michael L. 'Mike' O'Reilly is an attorney and was the mayor of Herndon from 2004 to 2006.

Starting in 2000, O'Reilly served two terms on the Herndon Town Council.

When Richard Thoesen declined to seek another term as mayor in 2004, O'Reilly was elected mayor in the May 4 elections, defeating Connie Haines Hutchinson and William B. Tirrell, Sr..

Controversy over Mayor O'Reilly's support of a day-labor center in Herndon led to his defeat by political neophyte Steven J. DeBenedittis in O'Reilly's reelection bid in 2006.
