About Colleen
Colleen Cornelison trained for law in Texas and entered practice soon after graduation. She earned her J.D. from Texas A&M University School of Law in 2018, having begun law study in 2015. The law school years placed her in a busy, practice-oriented environment and prepared her for immediate work in firm settings.
Her first position after law school was as an associate at Dunham and Jones in 2018. That role lasted a year before she joined Gill Law Office PLLC as an associate in 2019. These successive associate positions gave her day-to-day exposure to the routines of small firm practice and helped her adapt to the demands of client work and case preparation.
Over the next several years she moved into the Barnett Howard & Williams PLLC team. She is listed with the firm’s Keller and Grapevine offices and is part of the firm’s Texas-licensed roster. Colleagues describe her as steady and pragmatic in handling assignments, comfortable working across a range of matters that arise in regional firm practice.
Colleen practices under Texas jurisdiction. Her early career path — two associate posts followed by a role at a multi-office firm — reflects a common route for attorneys building practical skill sets in courtroom and office work. She has worked on matters that require coordination among attorneys and staff across multiple offices, and she has experience adjusting to the procedural requirements of Texas courts.
People who have worked with her note that she approaches cases methodically. She balances court calendars, client communications and document work in a way that suits a busy small- and mid-sized firm environment. The work calls for routine legal research, drafting and preparation for hearings; she has developed comfort with those tasks through hands-on practice rather than academic study alone.
Outside of the firm, she remains a Texas-licensed attorney and participates in professional life within the state. She continues to represent clients through the Barnett Howard & Williams PLLC Keller and Grapevine offices and handles matters across the firm’s Texas practice.
