Professional Liability Attorneys in Dallas

We Handle All Aspects of Malpractice Cases

Lawyers, engineers, accountants, and architects are among “professionals” whom people trust to perform specialized services for some of the most important matters in their lives. The law says professionals must meet minimum standards of care in the rendering of their professional services. Sometimes, a contract leads to litigation. Sometimes, a general contractor fails to properly implement the designed specifications provided by an engineer or architect. Sometimes, an engineer fails to approve a design in accordance with ordinances. All of these situations can invariably lead to litigation. We are here to help.

Our team of Texas professional liability attorneys has over 100 years of experience handling cases involving professional liability across the widest range of engineers, architects, accountants, lawyers, and other professionals. Cases involving allegations of malpractice often require the review and approval of another professional in the same field before a lawsuit can proceed. We understand the specific statutes, cases, and guidelines that govern professional conduct and utilize a vast array of proven and respected experts to identify issues where they exist and properly frame the issues for a judge, jury, or professional board to understand.

Advocating for Professionals

Our attorneys have handled multiple high-value cases stemming from allegations of not only medical and attorney malpractice, but those involving real estate agents, securities brokers, engineers, and more. We know what kind of work, evidence, and expert testimony is necessary to see a contentious professional liability case through to the end.
