Marc A. Grano
New Mexico Personal Injury and Criminal Defense Lawyer
25+ Years | Former State Prosecutor | Former Military JAG | NCDD New Mexico State Delegate
Most people do not call a lawyer on a good day. You may be facing a DWI or criminal charge that threatens your freedom, driver’s license, career, or reputation. Or you may be injured and dealing with an insurance company that does not have your interests at heart.
Either way, you need more than promises. You need clear answers, an honest assessment of your situation, and a lawyer prepared to do the work.
I am Marc A. Grano. For more than 25 years, I have represented people in New Mexico courts. I am a former New Mexico state prosecutor, former military JAG officer, and attorney-owner of Grano Law Offices, P.C. My practice focuses on DWI/DUI defense, criminal defense, and personal injury representation.
My office is based in Las Vegas, New Mexico, and I serve clients throughout northern and central New Mexico, including:
- Las Vegas
- Raton
- Mora
- Española
- Taos
- Santa Rosa
- Santa Fe
- Rio Rancho
- And surrounding communities
Helping Good People in a Bad Situation.
That is more than a tagline. A charge, accusation, or serious accident does not tell the whole story of a person’s life. My job is to listen, identify what matters, and help each client move forward with a plan.
Straight Answers and a Strategy Built for Your Case
I will not tell you what you want to hear simply to earn your business. I will tell you what I see in the evidence, what can be challenged, the risks, and what I recommend.
Every case is different, and no lawyer can guarantee a particular outcome. When you hire Grano Law Offices, P.C., you can expect:
- Direct, practical advice. I explain the law, your options, and the likely next steps in plain English.
- Individual attention. Your strategy is based on the facts of your case—not a standard template.
- Careful preparation. I look beyond the accusation to the evidence, procedure, science, and people involved.
- Responsive communication. My team and I work to keep you informed about what is happening with your case.
- Candid guidance. When a case should be challenged, I will. When another course better protects your interests, I will tell you that too.
Legal strategy and advice come from me, and I remain involved in the important decisions throughout your case.
The Perspective of a Former New Mexico State Prosecutor
Before becoming a criminal defense lawyer, I served as a New Mexico state prosecutor. That experience gave me firsthand insight into how criminal cases are investigated, charged, negotiated, and tried.
I understand how prosecutors evaluate police reports, officer testimony, witness credibility, forensic evidence, and trial risk. I use that perspective to anticipate the State’s theory, test its evidence, and identify weaknesses that may not be obvious at first glance.
Former state prosecutor experience is not a substitute for preparation. It tells me where to begin looking. The facts of each case determine where the defense goes from there.
Advanced DWI Training Grounded in Science
DUI/DWI cases in New Mexico are not just about what an officer wrote in a police report or what number appeared on a machine. Often, they involve blood analysis, breath-testing, medical conditions, observation, standardized field sobriety testing, toxicology, and administrative rules.
I have invested in advanced DWI training throughout my career so that I can examine that evidence at a deeper level. My selected training includes:
- National College for DUI Defense NHTSA-recognized DWI Detection and Standardized Field Sobriety Testing Practitioner Course (2026)
- National College for DUI Defense, Serious Science Advanced Course in Blood Alcohol Analysis and Trial Advocacy (2025)
- National College for DUI Defense, Breath Testing From Input to Verdict (2025)
- National College for DUI Defense, Serious Science Advanced Course in Blood Drug Analysis and Trial Advocacy (2024)
- NHTSA, Advanced Roadside Impaired Driving Enforcement (ARIDE) Course (2024)
- NHTSA/IACP, DWI Detection and Standardized Field Sobriety Testing Instructor Development Course (2023)
I also serve as the New Mexico State Delegate to the National College for DUI Defense and as a member of its National Task Force.
This training helps me evaluate whether an investigation was conducted properly, whether testing conditions affected reliability, whether an instrument or laboratory result can withstand scrutiny, and whether the evidence supports the State’s conclusions.
A DWI arrest can also create two separate proceedings: the criminal case and an administrative driver’s-license case. I regularly represent clients in Motor Vehicle Division license-revocation hearings and help them understand how the two proceedings may affect each other.
New Mexico Criminal Defense Focused on the Whole Person
A criminal case can affect far more than the courtroom. It can threaten employment, professional licensing, family relationships, driving ability, finances, and reputation.
I defend people accused of DWI/DUI and other misdemeanor and felony offenses in New Mexico. I examine the legality of the investigation, the reliability of the evidence, possible defenses, and the practical consequences of each available option.
My goal is to protect not only your legal rights but also the future that may be at risk due to the charge.
New Mexico Personal Injury Representation Built on Evidence
After a serious injury, an insurance company may appear helpful while gathering information to limit what it pays. I represent people injured in car, truck, and motorcycle crashes and other negligence cases, as well as families pursuing wrongful death claims.
I help clients understand their rights, document the full extent of their losses, and deal with insurers from an evidence-based position.
That means examining how the injury occurred, preserving evidence of liability, reviewing medical care, documenting lost income and other damages, and evaluating how the injury may affect the person and family over time. I prepare each claim with the expectation that the evidence—not slogans—must support the result we pursue.
New Mexico Roots and a Commitment to Service
New Mexico is not simply where I practice law. It is home.
I earned my bachelor’s degree in psychology from New Mexico Highlands University in 1993 and my Juris Doctor from the University of New Mexico School of Law in 1999. I was admitted to the New Mexico Bar in 2000.
My military path began in enlisted service and continued through Officer Candidate School and 19 years of combined service in the Army Reserve and the New Mexico Army National Guard. After completing the U.S. Army Judge Advocate Officer Basic Course in 2003, I served as a JAG officer, advising commanders and service members on matters requiring sound judgment, preparation, and integrity.
Service also extends beyond the courtroom. Since 2020, Grano Law Offices, P.C. has sponsored the annual Bikes for New Mexico Kids giveaway, providing bicycles to children in communities throughout the region.
