Colleen O'Brien

Colleen O'Brian is an Oakland County Circuit judge who ran with the Republican endorsement for the Michigan Supreme Court in 2012. She lost in the general election.

O'Brian has a bachelor's degree from the University of Michigan and a law degree from the Detroit College of Law. She became a judge of the 6th Circuit, that covers Oakland County, in 1998.

After Diane Hathaway resigned from the Michigan Supreme Court amid fraud charges O'Brien was seen as a strong candidate to replace her. The appointment eventually went to David Viviano of Macomb County.
