We do not simply process cases. We prepare every case with the expectation that it may need to be fought in court. Prosecutors negotiate differently when they know defense counsel is prepared, strategic, and ready for trial.

Geronimo Gutierrez IV previously served as a Los Angeles County Deputy Public Defender, where he represented individuals facing serious criminal charges and developed firsthand courtroom experience in one of the busiest criminal court systems in the country. That experience provides critical insight into how cases are charged, litigated, and defended throughout Southern California.

We appear regularly at the North Justice Center in Fullerton and other Orange County courthouses. We know the judges, the prosecutors, and the courtroom procedures—and that familiarity matters when building your defense.

Arrests, warrants, and investigations do not happen on a schedule. We are available around the clock to respond quickly, explain your options, and begin protecting you immediately.

We proudly serve Spanish-speaking clients and families throughout Orange County and Southern California.

Every case matters. Our goal is always to position your case for the best possible result—whether that means dismissal, diversion, reduced charges, avoiding custody, or winning at trial.

We appear regularly in Orange County Superior Court locations, including:

• North Justice Center (Fullerton) – 1275 N Berkeley Ave, Fullerton, CA 92832
• Central Justice Center (Santa Ana) – 700 Civic Center Dr W, Santa Ana, CA 92701
• Harbor Justice Center (Newport Beach) – 4601 Jamboree Rd, Newport Beach, CA 92660
• West Justice Center (Westminster) – 8141 13th St, Westminster, CA 92683

Our daily presence in these courthouses gives us familiarity with local judges, prosecutors, and courtroom procedures—an advantage that often makes the difference between conviction and dismissal.

The early stage of a criminal case often matters the most. We move quickly to assess the allegations, protect your rights, and identify opportunities to limit the damage before the prosecution gains momentum.

In many cases, the most effective defense begins before charges are ever filed. When contacted early, we can:

• Present evidence and witness statements to the investigating officer or detective
• Contact the district attorney's filing division directly
• Demonstrate weaknesses in the case that may lead to a decision not to file charges
• Negotiate alternatives such as civil compromise or diversion before formal charges

This approach can save you months of stress and protect your professional and personal life from public exposure.

We do not rely solely on the police report. We review body camera footage, witness statements, digital evidence, timelines, and physical evidence to identify weaknesses and inconsistencies in the government's case.

Not every case should resolve the same way. Some cases should be pushed toward dismissal, some toward reduction, and some toward diversion. We tailor strategy to the facts, the court, and your long-term goals.

Cases are strongest when they are prepared as though they will be tried. That preparation gives us leverage in negotiations and puts us in a stronger position if the matter must be litigated before a judge or jury.

We challenge illegal searches, unlawful detentions, unreliable statements, weak charging decisions, and insufficient evidence. A strong motion can reshape the case—or end it.

Past results do not guarantee future outcomes. Every case depends on its own facts, evidence, and circumstances.

Fees depend on the nature of the case, the seriousness of the charges, and how much litigation is required. We offer confidential consultations so you can understand the charges, likely next steps, and the scope of representation.

Remain silent, do not consent to searches, and contact a criminal defense attorney immediately. Do not discuss your case with police, cellmates, or anyone else before speaking with counsel.

Yes, depending on the facts. Charges may be challenged through motion practice (suppressing evidence, challenging probable cause), at preliminary hearings (insufficient evidence), or through negotiation with prosecutors. Early intervention by an experienced attorney significantly increases the chances of dismissal or charge reduction.

It depends on whether the matter is a misdemeanor or felony, whether the case is being investigated or already filed, and whether it resolves early or proceeds toward trial. Some cases resolve in weeks; others may take many months.

A misdemeanor is generally punishable by up to 1 year in county jail. A felony carries more serious consequences, including potential state prison exposure, higher fines, and long-term consequences including loss of voting rights, firearm restrictions, and professional license loss.

Not every case results in jail or prison. In many cases, there may be opportunities for diversion, probation, treatment-based outcomes, reduced charges, or credit time served. The facts of the case and the defense strategy matter.

Arraignment is usually the first court appearance after charges are filed. The court advises you of the charges, you enter a plea, and issues such as bail, release conditions, and future court dates are addressed.

In many cases, yes. Depending on the outcome of your case, you may be eligible for expungement or other post-conviction relief. Eligibility depends on the type of conviction, whether probation was completed, and other factors.

Pre-filing intervention is when your attorney contacts law enforcement or the district attorney's office before charges are formally filed to present evidence, witness statements, or legal arguments that may result in the case being rejected or significantly reduced.

Mental Health Diversion allows eligible defendants with qualifying mental health conditions to participate in treatment instead of prosecution. Successful completion results in dismissal of charges.

If you or a loved one is facing criminal charges in Orange County, contact Poseidon Defense A.P.C. for a confidential consultation. Early action can make a major difference in the outcome of your case.
