About Brett M
Brett M Chisum built a career that moves from communications to the courtroom. He studied mass communications and broadcasting before turning to law. The shift shaped how he approaches client matters: clear, direct, and practical.
He earned a Bachelor of Arts in Mass Communications and Broadcasting from Texas A&M University - West Texas A&M University in 2000. Ten years later he completed a J.D. at SMU Dedman School of Law, finishing law school in 2010. The two degrees give him an uncommon combination of media training and legal education.
Chisum has been active as a lawyer since at least 2012. That year he is listed as practicing at McCathern, PLLC. His path to private practice followed his time in Texas legal education and local bar circles. He has worked in the Dallas area and has built experience handling matters that arise under Texas law.
His professional affiliations are rooted in the Dallas legal community. He holds current memberships in the Dallas Bar Association and the Dallas Association of Young Lawyers. Those memberships connect him to local judges, litigators, and in-house counsel. They are also a regular source of continuing legal education and networking that inform the practical side of his work.
Colleagues and clients describe him as methodical and straightforward in handling cases. He applies skills from his communications background when preparing witnesses, drafting documents, or explaining legal issues to clients. The combination of media training and courtroom practice helps him distill complex information into clear guidance.
At McCathern, PLLC he has been part of a team working on a range of matters brought in Texas courts and agencies. He represents clients in settings that require both courtroom advocacy and careful preparation of pleadings and agreements. His work emphasizes attention to procedural detail and client communication.
Outside the office he remains tied to the Dallas legal scene through bar activities and events sponsored by the young lawyers association. That involvement keeps him current on developments in Texas practice and on the informal networks that often shape referrals and case strategy.
He currently practices law at McCathern, PLLC, where he serves clients across Texas through his work at the firm.
