Peter F. Iocona is a criminal defense lawyer specializing in defending those charged with Driving Under the Influence of Alcohol (DUI) and Driving Under the Influence of Drugs (DUI-D) in Southern California, particularly Orange County, California where the DUI Penalties are some of the most severe in the State of California. Mr. Iocona practices in both the State and Federal Courts of Southern California. Mr. Iocona is also a Personal Injury Attorney, having obtained favorable, high-valued outcomes on behalf of his clients.
As an accomplished trial attorney, Mr. Iocona has earned a reputation of being one of the best Trial Attorneys in Southern California, and because of this, was rated by Super Lawyers, a Thomas Reuters Attorney-Rating Service and has been named in The National Trial Lawyers: Top 100 and is known as one of Orange County's most accomplished trial lawyers.
Mr. Iocona holds an Avvo-Rating of "Superb" or "10/10" and OC Metro magazine listed him as one of the area's "Top-Rated DUI Attorneys in Orange County, California". Mr. Iocona has a reputation for being a zealous advocate and a seasoned trial attorney and one of his case was even featured in an article that was published in the OC Weekly in 2016: "OC Judge Slams Prosecutor for Misconduct, Prosecutor Gets Promoted by DA Tony Rackauckus". This article is part of a lengthy series of articles by Scott Moxley of the OC Weekly regarding what has become known as the "Orange County Snitch Scandal". The article addresses the extent of Prosecutorial Misconduct in Orange County stating that "Prosecutorial cheating apparently extends to relatively minor trials, too.", which Mr. Iocona exposed in 2015 during the trial of The People of the State of California vs. Sandra Goelman.
In 2015, Mr. Iocona was also selected as a "Superior DUI Attorney" by The National Advocacy for DUI Defense (NAFDD). That same year, he was also selected for inclusion in the 2015 list of the "Nation’s Top One Percent", which is published by the National Association of Distinguished Counsel (NADC).
In 2017, Mr. Iocona was selected into the list of America's Top 100 Criminal Defense Attorneys based on his work on Criminal Defense cases. This designation is awarded to only a select few of each jurisdiction's best criminal defense attorneys.
Peter F. Iocona began his career with the Law Office of Barry T. Simons in 2000. From 2003 to 2016, Mr. Iocona was a Contributing Editor to the two volume treatise: "California Drunk Driving Law", often considered the "Bible of Drunk Driving Law" in the State of California. Mr. Iocona would serve as the Lead Trial Attorney for the firm's DUI cases and was also the Managing Attorney of that firm from 2012 to 2016 to form The SoCal Law Network, with his then two law partners, Alan Castillo and Marlo Cordero. Mr. Iocona would later transition from The SoCal Law Network back to The Law Office of Peter F. Iocona, or Peter F. Iocona, Attorney at Law, which he began in 2009.
Peter F. Iocona is a member of the National College for DUI Defense (NCDD); DUI Defense Lawyers Association (DUIDLA), California DUI Lawyer's Association (CDLA); and California Association for Criminal Justice (CACJ), National Association of Criminal Defense Attorneys (NACDL). As a member of these organizations, Peter F. Iocona has received specialized training in the defense of those charged with DUI and Criminal Defense. Mr. Iocona has been certified under the standards set forth by the NHTSA (the National Highway Traffic Safety Administration) as an "SFST Administrator" and as an "SFST Instructor".
Mr. Iocona has received extensive training and instruction in the area of DUI Drugs, a new arena in DUI defense in light of the increasing rate of those being charged with DUI Drugs after consuming their prescription medications. Attorney Peter F. Iocona has received "Drug Recognition Expert" instruction and served as an “Expert Panelist” for a seminar sponsored by the O.C. (Orange County) Crime Laboratory and the California Association of Toxicologists, which was entitled: DUI Drugs, Says Who?
While Mr. Iocona specializes on DUI cases in Orange County, he also handles some of the most complicated Criminal Defense Cases in Orange County, such as: Child Molestation, or Committing Lewd Acts on a Child or Minor; Murder, Homicide, Voluntary Manslaughter, Involuntary Manslaughter; Sex Crimes, such as Sexual Assault or Rape; Statutory Rape; or Spousal Rape; Creating, Distributing, or Possessing Child Pornography; and Solicitation of a Minor; Prostitution, Pimping and Pandering, Human Trafficking or Solicitation of Prostitution; Domestic Violence, Assault and Battery, Assault With a Deadly Weapon, and Kidnapping; White Collar Crimes, Fraud, Grand Theft Embezzlement, Petty Theft Embezzlement, and Forgery; DUI, DUI Drugs, DUI With Injury, DUI With Great Bodily Injury, DUI Manslaughter, Watson Murder; Theft, Robbery, Burglary, Carjacking, Shoplifting and/or Petty Theft, Grand Theft, and Grand Theft Auto (GTA); Possession of Illegal Firearm, Carrying a Loaded Firearm in Public, Felon in Possession of Firearm, Brandishing a Weapon; Felony Criminal or Terroristic Threats, Misdemeanor Criminal or Terroristic Threats; Drug Possession, Drug Possession With Intent to Distribute; Internet/Online Fraud, Phishing or Identity Theft, Hacking; Felony Vandalism, Misdemeanor Vandalism; Felony & Misdemeanor Juvenile Charges; Expungements and Motions to Reduce.
Mr. Iocona also handles Professional Licensing Defense matters. It's rare to find a Professional Licensing Defense firm who also specializes in DUI and Criminal Defense matters. The two disciplines are often intertwined: professional licensees are charged with criminal offenses and/or professional licensees are charged with criminal behavior in the context of their fitness to be a professional licensee.
Mr. Iocona is committed to representing people across the entire State of California with challenges or accusations toward their professional license. Mr. Iocona represents professional licensees before the California Board of Medicine, the California Board of Registered Nursing, the California Board of Vocational Nursing & Psychiatric Technicians, the California Board of Psychology and the California Board of Behavioral Psychology, including Licensed Therapists and Licensed Marriage and Family Therapists (LMFT), California Real Estate Agents and California Real Estate Brokers, the California Board of Pharmacy, the California Board of Optometry, and the California Board of Accountancy.
If you are charged with a Crime, including DUI, or are facing an allegation or accusation from a Professional Licensing Board, contact Peter F. Iocona to obtain the best possible outcome and protect your rights from overreaching government actors and/or actions.
