Jeff Lahann, President


I fight for good people whose freedom and reputation are on the line. I’ve been practicing criminal law since 1991; starting as a prosecutor in Socorro and Truth or Consequences, then as a Deputy District Attorney for 9 years here in Las Cruces. I started The Lahann Law Firm in 2007 with the mission of providing the best possible defense for people accused of crimes in New Mexico.

When you’re facing serious criminal charges, your choice of who will defend you in court is the most important decision you will make. Your lawyer is the only person standing between your freedom and the vast resources of prosecutors who want to take it away.  I’ve tried over 300 felony cases as a prosecutor and a defense attorney and I’ve been very successful in convincing juries to see things my way and come back with verdicts favorable to my client.

I love being a trial lawyer and it shows in court. Frankly, I believe I’m one of the best at what I do. But don’t just take my word for it – ask around. I’ve represented hundreds of your friends, neighbors, classmates and colleagues here in Las Cruces. Everyone from high school and college students, to college professors and retirees. Yes, I’ve even defended those who know the criminal justice system the best: police officers, prosecutors, and judges.

Your criminal case is the most important thing in the world to you and I know it; that’s why I fight for every client with everything I’ve got.

Your choice of lawyer is the most important decision you will make. Come in and talk to me before you make that choice. I’ll give you an honest assessment about your case and whether our firm is a good fit for you.

Terese Lahann, Attorney

 Terese Lahann is an attorney with over 25 years of experience. She started her career as a prosecutor in the Seventh Judicial District working in Truth or Consequences, Socorro, and Estancia. During this time, Ms. Lahann handled all manner of cases, from misdemeanor DWI’s to high level felonies. After living in Estancia, Ms. Lahann decided that, while the scenery was lovely, the town was a little too small for her at the time, and she moved to Albuquerque to join a small firm with a varied practice. In 1996, she joined the public defender office in Alamogordo, gaining valuable practice and experience in criminal defense work. Following that, she returned to Truth or Consequences for a year as a partner in a law firm there focusing on criminal cases.

In 1998, an opportunity arose to join the Third Judicial District Attorney’s Office in Las Cruces. Ms. Lahann, a native of El Paso, Texas, and frequent visitor to Las Cruces as a child where her grandmother and other relatives were long-time residents, decided it was time to move closer to home and made the move to Las Cruces. While working with the District Attorney’s Office, Ms. Lahann served in the domestic violence, juvenile, general felony, and drug units.

From 2007 – 2016, Ms. Lahann had her own practice focusing on Children’s Court CYFD cases while continuing to consult and, at times, act as co-counsel in criminal cases. As of August 2016, Ms. Lahann joined The Lahann Law Firm in a desire to return to the primary practice of criminal defense. Ms. Lahann has long had a strong commitment to defending constitutional rights and will fight hard to protect those rights for each and every client. She will look at every aspect of your case, be a skilled advocate for you in court and work to get you the best possible outcome.
