Geronimo Gutierrez IV, Chief Counsel of 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 adds to a series of recognitions for Gutierrez. He received Avvo Client’s Choice recognition in 2025 and 2026 and was named a Martindale-Hubbell Platinum Client Champion in 2026. That recognition requires at least 10 client reviews and an average client-review score of 4.5 or higher.
Poseidon Defense A.P.C. is a Fullerton, California criminal defense law firm led by Gutierrez. The firm represents adults facing an arrest, criminal investigation, court date, warrant concern, DUI, felony, misdemeanor, domestic violence allegation, drug charge, probation issue, or serious criminal accusation in Orange County, Los Angeles County, and surrounding Southern California communities.
Clients and families often need immediate, confidential guidance after an arrest, citation, booking, release from custody, or notice to appear in court. The firm also serves people who need help understanding criminal court procedures, protecting their rights, responding to allegations, and preparing for California state or federal criminal matters.
Gutierrez built the firm after gaining experience in both private criminal defense and public defense, including work with the Los Angeles County Public Defender. Poseidon Defense was created so clients facing DUI, misdemeanor, felony, domestic violence, and serious criminal allegations can receive clear communication, careful preparation, and direct attention to their case.
“Hope for peace. Ready for trial,” said Geronimo Gutierrez IV, Chief Counsel.
Criminal cases move quickly, and decisions made early can affect what happens months later. Gutierrez brings experience from both public defense and private practice to that bigger picture. He looks closely at the evidence, explains the choices in plain English, and prepares with later hearings and trial in mind.
His continued training in DUI science, forensic evidence, and homicide defense reflects a commitment to doing the hard work each case deserves. Clients deserve an attorney who asks tough questions early and takes the time to explain what comes next.
Attorney Gutierrez has completed advanced continuing legal education through the California Public Defenders Association, including the 2026 DUI Defense Seminar and Homicide Defense Seminar. The training covered DUI testing, forensic DNA, implied malice, manslaughter, trial strategy, jury selection, expert evidence, and criminal case law.
