Since passing the Bar in 1993 (Texas) and 1994 (Louisiana) my practice has been primarily related to the defense of maritime and energy companies. The majority have involved personal injuries in stevedoring or energy related industries. Often these disputes have involved claims made under the Jones Act, Longshore and Harbor Workers Compensation Act or the Texas Worker ’s Compensation Act as well as the interpretation and litigation of Insurance Policies and Master Service Agreements. Actively counsel clients on financial/wealth management, taxation and investments. In the last three years, I have had a similar practice but have also become an active mediator of Longshore Act, Defense Base Act and complicated Insurance/Master Service Agreement disputes.

My typical client is a stevedore, shipping/trucking/pipeline operator, oil field service company, marine construction company, refinery, offshore platform owner/operator, manufacturer, employer of injured worker, renewable energy company or insurance company.  I appear in federal and state courts in Texas and Louisiana regularly.

I have appeared before OSHA investigators where criminal charges were involved and various municipal and state courts on behalf of clients for traffic offenses and other reasons.

I have tried over 75 cases in Federal and State District Courts in Texas and Louisiana and before Administrative Law Judges in Texas, Louisiana, Illinois, Kentucky, and California. I was lead counsel in all of them and generally sole counsel for my client.
