You Speak Directly With Dennis


One Relationship for Every Legal Need You'll Ever Have

Most people don't need one kind of lawyer. They need a lawyer who knows them — someone who handled their business contracts, helped them write their will, and is still there when an accident turns their life upside down. That's what our attorneys have offered Louisiana since 1971.


Dennis Pennington has been practicing law in Louisiana for many years. He handles business and corporate transactions, wills and estate planning, commercial and residential real estate closings, civil litigation and brings a wealth of experience when it comes to personal injury claims — not as separate departments, but as one attorney who carries the full picture of your legal life. When something comes up, you call one number. You reach the same person.

Planning for the future can feel complicated without clear direction. You get practical guidance on wills, trusts, and probate so your decisions are documented and enforceable.

What We Handle for Clients Across Louisiana

Personal Injury

If you or a family member were hurt in a car accident or lost someone to another driver's negligence, we handle the claim from the first call through resolution. Dennis works directly with adjusters and opposing counsel across the state — relationships built over five decades that move cases forward.

Business & Corporate Law

From LLC and stock transfers to mergers and acquisitions, we represent buyers, sellers, and business owners move ahead with their business planning and the "big deal."  We handle Complex transactions with the thoroughness of a large firm and the accessibility of a one on one practice.

Estate Planning

Wills, trusts, and Louisiana succession law — the planning that protects your family when you're no longer there to do it yourself. We take time with estate planning clients because the decisions you make today have consequences that outlast all of us.

Real Estate Transactions

Through our affiliated real estate title company, Acquire Title Services, Inc., we handle commercial and residential closings in Louisiana without the delays and coordination costs of a third-party title company. Your transaction stays in-house from contract to close.

Civil Litigation

When an insurance company underpays a claim, a business partnership falls apart, or a property dispute requires a court, we represent clients in Louisiana state courts and federal courts at every level.

50 Years of Experience. Rates From a Different Era.

The legal industry has changed a great deal since Dennis Pennington opened started practicing law in 1972. Our attorneys have chosen to make hiring a lawyer affordable — a deliberate choice, not an oversight. The clients he serves are families, business owners, and individuals going through some of the hardest moments of their lives. Pricing them out of quality legal representation has never been part of the model.


When you retain our lawyers, you get over half a century of experience, federal court admission through the U.S. Supreme Court, and direct access to your attorney — at a reasonable cost.

One ongoing relationship.
