If you're here, something just went wrong. Maybe badly wrong. You're not looking for marketing — you're trying to figure out who can actually stand up in court and protect you.
That's where I come in.
I'm Jeff Lahann, a criminal defense lawyer based in Las Cruces, New Mexico. I represent clients facing serious criminal charges throughout Doña Ana County and southern New Mexico — including felony cases, DWI, and high-exposure investigations.
I've been practicing criminal law in New Mexico since 1991 — and I've stood on both sides of the courtroom.
I started as a prosecutor in Socorro and Truth or Consequences, then spent nearly a decade as a Deputy District Attorney here in Las Cruces. I've stood on both sides of the courtroom — and I've tried over 300 felony cases.
That matters more than anything else you'll read on this page.
Because when your case gets serious — and sometimes even when it doesn't — you're not negotiating with a website or a reputation. You're facing prosecutors preparing for trial.
The question is whether your lawyer is too. I am.
I've represented clients across Las Cruces — from students to professionals to people whose careers depend on the outcome. I've also defended individuals who understand the system from the inside: law enforcement officers, attorneys, and judges.
When the stakes are that high, the defense has to be airtight.
What I will do is sit down with you and give you a clear, unvarnished assessment of where you stand. Not what you want to hear — what you need to know.
Because your freedom, your record, and your reputation are on the line.
Good people in bad situations. High-stakes cases. Moments where everything is on the line.
I represent clients throughout Las Cruces, Doña Ana County, and southern New Mexico who need serious criminal defense — not volume representation.
You'll deal directly with me. Not an associate. Not a gatekeeper.
You'll get straight answers. You'll know where you stand. And if I take your case, you'll know exactly who is standing between you and the State of New Mexico.
Because the prosecutors know who I am. Because the judges know how I try cases.
Because when it matters, experience isn't a slogan — it's leverage.
I focus on serious criminal defense matters in Doña Ana County and throughout southern New Mexico. I don't spread myself thin. I don't chase volume. I prepare cases to be won.
High-stakes criminal charges where your freedom and future are on the line. Decades of trial experience, on both sides of the table.
Aggravated assault, battery, weapons charges, homicide. The cases the State takes most seriously demand a defense built for trial from day one.
Possession, distribution, trafficking, conspiracy. Search-and-seizure issues are often the case — and where the defense is won.
First offense or fifth, the consequences are real — license, job, freedom. I know New Mexico DWI law and the local courts inside and out.
Embezzlement, fraud, financial crimes, professional misconduct. When a charge could end a career, the defense has to be airtight.
An old conviction shouldn't define the rest of your life. New Mexico's full expungement process — petition through hearing.
Serious charges demand a lawyer who has stood at counsel table hundreds of times.
I've represented clients across Las Cruces — from students to professionals to people whose careers depend on the outcome. I've also defended individuals who understand the system from the inside: law enforcement officers, attorneys, and judges.
When the stakes are that high, the defense has to be airtight.
Whether it's a first offense or not, a DWI charge in New Mexico carries real consequences — your license, your job, your record.
I know the courts in Las Cruces and Doña Ana County. I know how these cases are prosecuted. And I know where they can be challenged.
An old conviction shouldn't define the rest of your life.
I handle expungement cases in New Mexico from petition through hearing — but only when it can be done right. Clearing your record is not just paperwork. It's strategy.
If law enforcement has contacted you but hasn't filed charges yet, this is the moment that matters most.
Do not try to explain. Do not try to "clear things up."

Your son or daughter goes off to school in Las Cruces. Then the call comes — late at night.
They've been arrested. Or cited. Or questioned. And they don't know what to do.
You're not here. I am.
I can be at the Doña Ana County Detention Center, in court, and on the phone with you — immediately. I know how these cases unfold here, and I know how to protect their future before things spiral.

Mr. Lahann truly represented me with his heart. His devotion to my case was palpable in the courtroom. If you are looking for a good defense attorney, look elsewhere. If you are looking for the best — Jeff Lahann is who you want on your side.
When it mattered most in the courtroom, the prosecution was no match for his experience. He made their case fall apart right before our eyes. The smile and wink from Jeff to my family after the “Not Guilty” verdict was read is forever etched in our memory.
Right from the start, Mr. Lahann informed me of my rights and the entire office treated me like family. They were very knowledgeable and explained to me exactly what was going to happen. I called a lot, and was always treated with respect.
Jeff is an amazing attorney who works hard to ensure winning results. His staff is incredibly knowledgeable and friendly. Thanks Lahann Law Firm for all your hard work — I am truly grateful.
I'll tell you whether I'm the right lawyer for you. No pressure. No performance.
Just the truth — and a plan.
