About me

  Daniel attended The University of Texas School of Law in 2004. While there, he competed nationally and internationally in both moot court and mock trial, winning several awards along the way. He was also the recipient of two different merit-based Presidential scholarships, an associate editor on The Review of Litigation, and a member of the Board of Advocates. In 2007, he graduated, with honors, and moved to Houston to begin his practice.

     Initially, Daniel went to work for one of Houston's largest defense firms where he gained invaluable insight into the mentality of defense lawyers, insurance companies, and the large corporations that have been sued for alleged bad acts. While there, Daniel successfully defended cases of many different types, including: breach of contract; negligence; wrongful death; fraud; bad faith; premises liability; civil RICO; trade secret misappropriation; Deceptive Trade Practices Act; Jones Act; and more. But after three years of defending against such claims, Daniel decided that it was time to represent the people who were harmed by such acts.

    Consequently, Daniel left the world of defense to pursue a career as a plaintiff's attorney with Jim Adler & Associates. Serving as one of only two trial lawyers in Adler's Houston office, Daniel successfully obtained multiple judgments and settlements in favor of individuals who had been harmed by other people's negligence. Never afraid to take a case all the way through trial, Daniel has great confidence in the ability of a well-informed jury to make a just decision.

     Drawing on his past experiences from both sides of the isle, Daniel founded The Dinneen Law Firm in order to help those who cannot help themselves. Whatever the nature of a client's legal problem, Daniel is able to provide dynamic solutions with an attentative approach to his client's needs.
