   Welcome to the Ontario County District Attorney's Office Website. In the related pages at this site, you will find information regarding our duties and responsibilities, the service we offer, the courts we serve and various statistical data.

    The District Attorney is a State Constitutional Officer, elected by the county electorate for a four-year term. As the County's chief law enforcement officer, the District Attorney is responsible for the prosecution of all violations of the law that occur within the county's borders. These prosecutions include felonies, misdemeanors, violations and traffic infractions.

    Additionally, the District Attorney is responsible for handling criminal appeals at all levels of state and federal courts. Ancillary responsibilities of the District Attorney include prosecuting forfeiture proceedings, extraditing criminals from outside the state, and working with victims of crime to help them secure the fullest measure of redress allowed by law. Finally, the District Attorney is regularly called upon to advise various law enforcement agencies throughout the county.

    In Ontario County, we prosecute upwards of three thousand criminal cases each year. During my tenure, Ontario County has frequently had the highest felony conviction rate and the highest DWI conviction rate in the State of New York. This success is due to the hard work and dedication of quality prosecutors in this office, and to solid investigative work performed by well-trained police officers throughout Ontario County.

    Through this website we have endeavored to provide meaningful information to you. In turn, I encourage you to communicate with us if you have issues, concerns or questions about the criminal justice system. The fight against crime is continuous and never-ending, but we can provide an effective response that holds offenders accountable, and improves the quality of life in our communities, if we all work together.

      Sincerely
