There is a particular kind of chaos that follows a serious accident. Medical bills start arriving before the bruises fade. Insurance adjusters call with offers that sound reasonable until you realize they aren’t. And the legal system — built for lawyers, not everyday people — sits between an injured person and the compensation they’re owed.
For more than 40 years, Mullen and Mullen Law Firm has worked to close that gap for people across Dallas and the greater North Texas region.
The firm was founded in 1983 by Regis L. Mullen, a former litigation supervisor at Allstate Insurance Company who spent years on the other side of the negotiating table. That insider experience shaped everything about how the firm operates. Regis understood exactly how insurance carriers approach injury claims, what arguments they lean on to minimize payouts, and where injured claimants are most vulnerable without proper representation. He built a practice specifically designed to counter those tactics.
Today, the firm is led by Managing Partner Shane V. Mullen, who has handled personal injury cases for 24 years and has been recognized as a Texas Super Lawyer by Thomson Reuters for three consecutive years. Senior Associate Joseph R. Morrison brings 21 years of experience to the team, including a case against a Fortune 500 company that ranked among the top five premises liability verdicts in the state of Texas. Together with Regis, the three attorneys bring over 104 years of combined legal experience to every case that comes through the door.
The work they do covers the full range of circumstances that leave people injured and without a clear path forward. Car accidents are among the most common — particularly in a metro as dense and fast-moving as Dallas — but the firm also handles commercial truck accidents, motorcycle crashes, rideshare accidents involving Uber and Lyft drivers, pedestrian injuries, workplace accidents, premises liability cases, wrongful death claims, dog bites, and traumatic brain injuries, among others.
One of the more practical distinctions Mullen & Mullen offers is a reduced contingency fee. Most personal injury firms in Texas charge between 33.3 and 35 percent of a pre-suit settlement. Mullen & Mullen charges 29 percent on cases that resolve without litigation, which tends to be the majority of what they handle. For a family dealing with significant medical expenses and lost income after an accident, that difference translates directly into money they actually receive.
The firm also maintains two full-time accident investigators on staff, offered to clients at no additional charge. This is a resource most firms bill back to the client or skip entirely. Mullen & Mullen also employs an in-house videographer — a meaningful tool in cases where the long-term impact of an injury on someone’s daily life needs to be communicated clearly to an insurance company or jury.
For people who do not have health insurance or cannot afford upfront treatment costs, the firm connects clients with a network of physicians, surgeons, chiropractors, neurologists, and physical therapists throughout the DFW Metroplex who will defer billing until a case resolves. This is not a minor logistical detail. For someone who has just been seriously injured and is not in a financial position to pay out of pocket for diagnostics and ongoing care, this structure makes proper medical treatment actually accessible.
According to TopVerdict.com, an independent organization that tracks and ranks civil case results, Mullen & Mullen has appeared on their Texas top settlement lists 105 times over the last five years. The firm has also placed nine times on the number-one settlement list for Dallas County across different case categories. Recent publicly available results include a $6.15 million recovery in a workplace accident case and multiple vehicle accident settlements exceeding $2.5 million. The firm estimates its total recoveries over its history have exceeded $800 million.
Top Choice Awards, which ranks professional service firms based on customer satisfaction surveys, has named Mullen & Mullen the top injury law firm in Dallas for eight consecutive years, from 2019 through 2026.
What the numbers don’t fully capture is how the firm interacts with clients during a period that is typically one of the most stressful of their lives. Client reviews consistently describe attorneys who return calls, explain legal processes in plain language, provide direct cell phone access to the attorney handling the case rather than routing clients through layers of staff, and who show up to home visits and hospital rooms when a client can’t easily travel. These are not standard practices at high-volume law firms.
The firm also operates within a clear community orientation. Mullen & Mullen has been rooted in North Texas since its founding and actively supports local charitable causes through its Friends of Mullen & Mullen program. They also maintain a dedicated veterans and first responders program, recognizing a population that often has unique legal needs and limited resources for navigating the civil system.
For Dallas residents dealing with the aftermath of an accident — whether they lost income, face ongoing medical costs, or are simply trying to understand their options — the firm offers a free initial consultation with no obligation to retain. The Texas statute of limitations for personal injury cases is two years from the date of the accident, which means waiting rarely works in a claimant’s favor. See More
