Trial Attorney

As a founding partner of Doyle Dennis, Patrick has substantial involvement in the firm’s trial preparation and victories.  The firm’s victories include many multi-million dollar jury verdicts obtained under the Jones Act, general maritime law, section 905(b), and admiralty law.  Patrick’s offshore trial practice includes cases involving defective equipment, under-manning, negligent crane operations, poor maintenance, nonskid surfacing, ladder, and stair safety, failure to pay maintenance and cure, offshore explosions, poor vessel maintenance, negligent vessel construction, negligent use of crew transfer equipment/baskets, and various other kinds of Jones Act, LHWCA § 905(b), maritime law, and admiralty law cases.

In addition, Doyle Dennis is proud of its ability to represent offshore workers and seamen in cases brought in the United States that involve various types of international work.  Patrick’s past experience includes assisting crewmembers with cases involving injuries offshore involving South East Asia, Indonesia, Malaysia, Thailand, Australia, England, Scotland, Russia, Greece, Panama, Mexico, Canada, the Bahamas, the Virgin Islands, Brazil, New Zealand, Angola, South Africa, French Guiana, and the Marshall Islands, among others.


Patrick was born and raised in Houston, Texas, and is a proud graduate of The University of Houston, summa cum laude, and The University of Texas School of Law, with honors.

As a native of the Gulf coast, Patrick has seen the importance of the offshore, maritime, and oil and gas industries to the Texas, Louisiana, Gulf Coast, and United States economy.  He grew up with family members and friends who worked offshore on rigs, drill ships, jack-ups, tow boats, tugboats, crew boats, barges, cargo ships, bulk carriers, container vessels, tankers, seismic vessels, and other offshore ships.

These years of experience have helped Patrick to recognize the importance of following safety rules and industry standards in offshore and maritime work. Patrick has approximately two decades of experience in representing crewmembers, Jones Act seaman, Longshoremen, and offshore/maritime workers involving cases, clients, and incidents in Texas, Louisiana, Mississippi, Alabama, Florida, California, Kentucky, Ohio, Illinois, South Carolina, Virginia, New York, Massachusetts, Washington, Alaska, Nevada, Wyoming, Arizona, Nevada, and various other states and United States territories, like Puerto Rico.
