Allen residents will choose a new Collin County commissioner in the Nov. 3 election, with early voting starting Monday, Oct. 19.

Democrat Julie Holmer and Republican Shelby Williams, both former Plano City Council members, are competing for the Precinct 4 seat. The precinct covers Allen, Plano and parts of Carrollton and Dallas, according to Community Impact.

The winner replaces Commissioner Duncan Webb, who has held the seat since 2011. Webb helped secure more than $600 million in state funding for new limited-access roadways during his tenure, according to Collin County. The four-member Commissioners Court sets the county budget and oversees services including public works and health care.

Julie Holmer

Holmer, a small business owner and marketing professional, served more than four years on the Plano City Council, including time as deputy mayor pro tem. She resigned in November 2025 to run for the Precinct 4 seat. She has lived in the district since 1981 and is a graduate of Plano Senior High and Stephen F. Austin State University.

At a Collin County League of Women Voters forum ahead of the March primary, as KERA News reported, Holmer said the region's rapid growth demands coordination between city and county governments. "We want to make sure we're not duplicating efforts with our cities so that we can maximize our tax dollars at the city level and at the county level as well," she said at the forum.

Holmer has also pointed to gaps in county services, including the lack of a 24-hour emergency homeless shelter and no public hospital for uninsured and underinsured residents.

Shelby Williams

Williams served on the Plano City Council from 2019 to 2025 and previously chaired Collin County's Republican Party. The council accepted his resignation at a special meeting in March 2025. He works in consulting.

Williams has focused his campaign on infrastructure, identifying water supply and energy as top concerns. His campaign website says the county is "not building infrastructure fast enough to keep pace with our growth."

At a Collin County Conservative Republicans forum during the primary campaign, Williams said the county must act before population surges strain services. Collin County's population is expected to nearly double to more than 2.2 million by 2060, according to the Texas Demographic Center as reported by The Dallas Morning News.

Williams lists endorsements from Gov. Greg Abbott, the incoming Collin County Commissioners Court and the Plano and Dallas police associations, among others.
