Prior results do not guarantee a similar outcome. Every case is different and depends on its own facts and circumstances. Client last names are abbreviated for privacy.

Criminal Defense A conviction can follow you into every job application and background check. We defend misdemeanor and felony charges at every stage, from investigation through trial.

DUI Defense A DUI arrest starts two cases at once. One is the criminal case in court. The other is a separate DMV action against your license, and you have only 10 calendar days, weekends included, to request a hearing. A DUI lawyer in Rancho Cucamonga should be working on both from day one.

Crime Rates in Ontario, CA

According to an FBI crime report, Ontario had a total of 659 reported violent crimes in 2019, which include murder, rape, robbery, and aggravated assault. There were also 4,290 reported property crimes, including burglary, theft, and motor vehicle theft.

While these statistics may seem concerning, it doesn’t necessarily mean Ontario is a dangerous place to live. In 2019, Ontario had a population of 183,322. Therefore, crime rates here may be larger than in much smaller cities.
