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.
