Greg Willis is committed to the safety of Collin County citizens and is honored to serve them as Criminal District Attorney.  In fact, Willis resigned his judgeship to do just that.  As a Collin County judge hearing primarily criminal cases, Willis presided over hundreds of jury trials and thousands of cases.  As a Collin County prosecutor, Willis prosecuted cases ranging from speeding appeals to sexual assault and murder. As a Collin County private practice attorney, Willis represented scores of civil and criminal clients.

Having earned the community’s respect by excelling in each area of the criminal justice system, Willis is now honored to lead an Office whose mission is to fight and prosecute crime in a fearless, just, and ethical manner.  Willis understands that he is the temporary steward of the people’s trust.  His goals are to make Collin County a safer place and to strengthen community confidence in the Collin County criminal justice system.

Twice selected by his peers as a Texas SuperLawyer® (Texas Monthly), Willis has also served his fellow attorneys in various leadership roles, including as president of the Collin County Bar Association, and as a Life Fellow of the Texas Bar Foundation.  Willis, a long-time Rotarian, is also honored to serve on the board of directors for the Collin County Children’s Advocacy Center.

A fifth-generation Texan and married father of two, Willis is a graduate of Baylor University (1986, with honors) and the University of Virginia School of Law (1991).

Willis spent his first four years working in Dallas for the highly respected law firms of Haynes & Boone and Jones Day.  But once he paid off his student loans, Willis followed his heart to serve Collin County as both a misdemeanor and a felony prosecutor (1995-1999).

In late 1999, Willis returned to the private sector and established his own law firm in Plano.  His wife would later join him in this endeavor.  In late 2005, Collin County commissioners appointed Willis as the first judge of the newly created Collin County Court at Law No. 6.  Willis ran unopposed in 2006.  In October 2009, he resigned his judgeship to run for Collin County Criminal District Attorney.  In 2010, with the help of so many citizens who care deeply about the county, Willis prevailed in both the primary and general elections.
