Geronimo Gutierrez IV, Chief Counsel at Poseidon Defense A.P.C., has been selected to the 2027 Southern California Super Lawyers Rising Stars list for criminal defense. The recognition is limited to no more than 2.5 percent of attorneys in each state. The selection places Gutierrez among a small group of California lawyers identified for their work in criminal defense.
Poseidon Defense A.P.C. is a Fullerton criminal defense law firm serving Orange County, Los Angeles County, and Southern California. The firm represents people facing DUI, felony, misdemeanor, domestic violence, drug crime, probation violations, warrants, and other criminal charges in California state and federal court. Clients include adults and families who need a criminal defense attorney after an arrest, DUI stop, domestic violence allegation, felony charge, misdemeanor charge, warrant, probation issue, or upcoming criminal court date.
Many clients contact the firm when they are worried about jail, a driver’s license, employment, immigration consequences, professional licensing, family concerns, or what to say to law enforcement. The firm helps clients understand what happens after an arrest, court notice, or criminal investigation, then prepares a defense based on the facts, evidence, and legal issues in the case.
Gutierrez founded the firm with a belief that when someone is arrested or accused of a crime, they need more than a quick answer. They need an attorney who will slow down, examine the facts, and help them understand the decisions ahead. His experience in public defense and private criminal practice shaped a client-focused approach built on preparation, direct communication, and respect.
A criminal case is not only about the next hearing. Choices made at the beginning can affect evidence, negotiations, witness preparation, motions, and trial later on. Poseidon Defense A.P.C. approaches each criminal case with that full timeline in mind. Gutierrez brings public defense and private-practice experience, then continues building his skills through training in DUI defense, forensic evidence, homicide litigation, and courtroom advocacy. Clients receive a plain-English explanation of the process, direct attention to the issues that matter, and preparation for what may come next in California state or federal court.
Gutierrez completed the California Public Defenders Association’s 2026 DUI Defense Seminar and Homicide Defense Seminar. The training covered DUI testing, forensic evidence, implied malice, manslaughter, trial advocacy, jury selection, DNA evidence, and homicide case law. He also received Avvo Client’s Choice recognition in 2025 and 2026 and was named a Martindale-Hubbell Platinum Client Champion in 2026 after receiving at least 10 client reviews with an average score of 4.5 or higher.
