If you or someone you know has been arrested, charged, or investigated for a crime, you need someone to fight for you. A criminal case can have far reaching consequences and you need an experienced and effective defense attorney to help you during this process. Ryan Sullivan is the Lowell criminal defense lawyer you need.

Ryan Sullivan is a criminal defense attorney with an office in downtown Lowell. At the Law Office of Ryan P. Sullivan, we handle any criminal defense case – nothing is too large or too small – with our client-based approach from investigation all the way to trial. Communication, strategy, and experience are what we combine to give each person charged with a crime in a Massachusetts District Court or Superior Court the key to a unique, tested, and confident approach to achieving the best possible results.

Attorney Ryan Sullivan is a former prosecutor who has years of experience trying cases, leading investigations, and negotiating great results. He now uses these tools he learned as a former assistant district attorney in Middlesex County to help his clients by preventing charges from issuing, getting a charge dismissed, trying cases to a jury, or more.

“I cannot say enough about what a great attorney Ryan Sullivan is – there are few attorneys in Massachusetts capable of providing the legal representation [he does]”

– a former client in the Lowell District Court

Mr. Sullivan has handled hundreds of cases in district courts all across Middlesex, Essex, Worcester, and Suffolk Counties. When you hire Ryan Sullivan to represent you, he is taking all of his experience and putting it to work for you.

Drunk Driving / DUI Cases

Drunk driving is a charge that can affect anyone. In Massachusetts, it is referred to as operating under the influence (OUI) of alcohol (or drugs). Attorney Sullivan has handled numerous OUI and OUI drug offenses in courthouses in Lowell, Lawrence, Ayer, Concord, Haverhill, Newburyport, and many courts in Worcester County. Attorney Sullivan’s aggressive representation and experience in handling OUI cases have led to not-guilty verdicts, dismissals, and charge reductions. As a well-known Lowell criminal defense lawyer, Attorney Sullivan uses his creative arguments, diligent approach, and vast knowledge to represent his clients and achieve great results.

Domestic Assault and Battery

Domestic violence charges are very common in Massachusetts courts. Attorney Sullivan has represented many people charged with assault, assault and battery, assault and battery with a dangerous weapon, and other violent crimes. When the victim is a spouse, in a dating relationship, a roommate, or a family member, the charges become assault and battery on a family or household member. Prosecutors in Massachusetts work hard to get convictions on these charges – even if the victim wants to “drop the charges.” Having an aggressive attorney on your side can mean all the difference when the consequences are so severe.

Drug Charges

Attorney Sullivan handles all types of cases from drug possession, drug distribution, or drug trafficking. Being able to point out problems with the police investigation, the search warrant, or the informant can be the foundation to building the best defense possible. Attorney Sullivan uses his experience as a former prosecutor and his skills learned in trying drug cases to come up with a unique and creative approach when defending clients charged with drug crimes.

Recently Massachusetts prosecutors and police have been cracking down on drug dealing – especially with heroin and fentanyl charges. The moment the police have started an investigation is the time to call an experienced Lowell drug defense attorney. Attorney Sullivan has negotiated deals, won motions that suppressed evidence (so that it could not be used at trial), and successfully argued to juries in various court houses that the evidence was not enough – resulting in dismissals, not guilty findings, and reduced charges.

Restraining Orders

Attorney Sullivan has handled numerous restraining orders – both defending against unnecessary orders and assisting those who truly need them. Many times in the breakup of a relationship or a divorce one person will seek to get a restraining order in order to gain advantage. Attorney Sullivan uses his skills of cross-examining the person seeking the order (called the plaintiff) to poke holes in their case and expose their true intentions to the judge. The consequences of a restraining order can be disastrous: losing your home, your job, your ability to carry a weapon, and can be used in court negatively in the future. These are all reasons why you should have a skilled attorney representing your interest if you are the defendant in a restraining order.

Guns and Weapons

As a Lowell criminal defense lawyer, Attorney Sullivan handles many cases involving illegal possession of guns and other weapons. The penalty for possessing a gun without a license usually involves mandatory jail time if convicted. Second offenses or those with other prior criminal cases can make the charges even more serious. Attorney Sullivan has a track record of successfully representing people charged with firearm offenses. Call him today if you or a loved one is charged with a gun charge. Having a skilled lawyer represent you may be the difference between going to jail or going home.

Theft and Robbery

Charges of larceny and robbery have serious consequences. If the value of the property is over $250 or there is force used, the charges are likely going to be brought as a felony. The penalty for a felony conviction can result in loss of housing, being fired from your job, failing background checks, or even being unable to get a loan. Even a charge of shoplifting can have unexpected and far-reaching consequences.

Whether you are being investigated for or charged with a crime of shoplifting, larceny, receiving stolen property, or robbery, call Attorney Sullivan right away. Many times these charges arise as a result of a misunderstanding – but talking to the police may not clear that up. Attorney Sullivan has represented countless people who have had their statements to the police used against them later. Have an experienced criminal defense attorney by your side helping you or a loved one charged with a theft or property offense.

Clerk’s Hearings

The police do not always arrest those who are accused of crimes. For many people charged, but not arrested, the first step is to have a hearing before a clerk magistrate (often called clerk’s hearings or magistrate hearings). While it may not seem serious when you are called to court for a hearing, not having an experienced and knowledgeable attorney represent at this time may lead to the charges issuing. It is important to make the right arguments, point out the problems with the case, and inform the clerk magistrate why charges in your case should not issue. If you or someone you know has a clerk’s hearing, call Attorney Sullivan today to schedule your free consultation.
