Courtroom and investigative experience across Arizona's most serious criminal and injury matters.
Prosecutorial knowledge, applied to your defense.
The difference between a former prosecutor and a Major Felony prosecutor is not a distinction without a difference.
Long & Simmons Law was built by attorneys who handled homicide, major felony, kidnapping, home invasion, sex crimes, and complex multi-defendant matters before defending clients against them.
From DUI and serious felonies to first-degree murder and homicide cases.
Extensive experience in complex case litigation.
Criminal Law Specialist designation independently verified by the State Bar of Arizona.
A Partnership Built on Prosecutorial Depth
Long & Simmons Law is not a general practice firm that handles criminal cases among many other areas. It is built around the knowledge, experience, and resources required to defend serious criminal charges and pursue serious injury claims.
Both partners are former Major Felony prosecutors who tried the most serious cases the state brings. That specific background is a working method: start with the investigation, hold every government step to the standard it was required to meet, and make every deficiency matter.
The attorneys at Long & Simmons Law know how cases are built because they built them. They know where those cases fail because they have found every failure.
A Full-Service Practice: Criminal and Civil
Long & Simmons Law handles serious criminal defense alongside personal injury matters including vehicle accidents, commercial trucking, wrongful death, and serious injury claims. Every area of the practice is approached with the same forensic standard.
Access to Investigators and Experts
The firm works with accident reconstructionists, former law enforcement investigators, and forensic specialists who preserve evidence, analyze scenes, and build the factual foundation a serious case requires.

High-Profile Case Consultation
The firm's experience has been sought for matters involving prosecutorial standards, forensic investigation, constitutional process, and public-interest criminal cases.
What Every Client Can Expect
The methodology is consistent across every practice area and every case. It begins with the investigation, then builds strategy from the facts, the process, and the law.
The Investigation Comes First
Every criminal defense or personal injury matter begins with an independent assessment of what evidence was gathered, how it was gathered, and whether the process was legally and procedurally sound.
Forensic Resources Applied Immediately
Accident reconstructionists, former law enforcement investigators, and forensic specialists are engaged early when a case requires evidence preservation and technical analysis.
Pre-File Engagement Available
The period before charges are filed or before a claim is formally asserted can be the most valuable time to preserve evidence, conduct a parallel investigation, and shape the case.
Prepared for Trial From Day One
Long & Simmons Law prepares cases for trial, not just settlement. That approach changes negotiations with prosecutors, insurers, and opposing counsel.
Clear, Consistent Communication
Clients should understand where their case stands, what the realistic options are, and what comes next. Direct attorney access is part of the firm's standard.
Criminal and Civil Coverage
A serious event can create a criminal investigation, civil injury claim, MVD proceeding, and insurance dispute at once. The firm understands how those tracks interact.
The clients who come to us are facing the most serious situations of their lives. They deserve to know the difference between a marketing label and real major felony trial experience.
