As a retired Army officer, I know how important your service is, so I offer special rates for veterans and union members. For a free consultation, call Attorney John F. O'Brien today.

Tenacious Defender Handles Assault Charges

Assault is a serious crime in Connecticut that can carry severe penalties, depending on intent, the extent of the injuries, and whether a weapon was used.


  • First- and second-degree assault charges are felonies. Penalties for first-degree assault range from a minimum of five years in prison up to 20 years if a gun or other weapon was involved and other circumstances were present.
  • A second-degree assault can be charged for administering a debilitating drug to someone without their consent.
  • Third-degree assault is a misdemeanor but can result in imprisonment up to a year and $2,000 in fines.


If you’re accused of assaulting another person, I’ll review the details of your case to determine a possible defense that may include self-defense, defending another person, or defending property.

Experienced Advice for Clients Facing Sex Crime Counts

Sex crimes in Connecticut include sexual assault in varying degrees, incest, child pornography, and sexual abuse, among others. Sex offenses carry a range of penalties depending upon the circumstances involved, but the most severe penalties are for sexual assault in the first degree, commonly referred to as rape. Those convicted of the most serious charges face not only incarceration but also inclusion on a sex offender registry, a result with lifelong consequences.


If you’re arrested for a sex crime, I will seek to investigate whether consent or other factors can be used in your defense, to protect your rights and your reputation.

Skillful Defenses for Those Accused of White-Collar Crime

While white-collar crimes lack physical violence, they still hurt victims by stealing their money, property, or even identities, which is why they are severely penalized.


If you’re accused of committing fraud, money laundering, insider trading, or internet crime, you may be facing prosecution from the federal government, state government, or both, depending upon the jurisdiction involved. I have experience trying cases in both state and federal courts and will vigorously represent your interests.

Proven Advocate Handles OUI and Traffic Violations

If you’re convicted of operating a vehicle under the influence of alcohol or drugs in Connecticut, and it’s your first offense, you face criminal penalties that may include up to six months in jail, suspension of your license, and the imposition of an interlock ignition device on your vehicle.


Subsequent convictions carry stiffer penalties, and a third conviction could result in a permanent revocation of your license, seriously affecting your ability to work and support yourself and your family. In your defense, I will work to challenge the stop, other police procedures, and the results of breathalyzers and other tests, which may be faulty if instruments were improperly calibrated.


I also represent clients who’ve been cited for traffic violations such as speeding and reckless driving. If you’ve been ticketed, it’s important to know you have rights. I’ll fight the citation to reduce the chance that you’ll be fined, face points on your license, and have to pay higher insurance premiums.
