Professional Malpractice

Engineers, construction companies, accountants, and lawyers all have a professional duty to provide skilled, ethical, and reliable services in their respective fields.

Our firm represents clients across Oklahoma who have been harmed by professional negligence, including cases involving prior legal representation. If you believe your former attorney, accountant, engineer, or other professional acted negligently, we will carefully evaluate your situation and guide you through the next steps with clarity, confidence, and a commitment to protecting your rights.

Brandes & Yancy Office

I came to Brandes & Yancy after my insurance company denied a valid claim. They took the time to understand my situation, built a strong case, and didn't flinch when the insurer pushed back. Their attention to detail and courtroom presence made all the difference. I wouldn't trust anyone else in a fight like this.
