Glasgow & Olsson

Glasgow & Olsson Criminal and Divorce And Litigation Attorneys. When you need help, experience matters. "I served as a State's Attorney because I wanted to help people.

Before opening Glasgow & Olsson in Schaumburg, Illinois, Attorney Thomas Glasgow was a Cook County State's Attorney who prosecuted cases ranging from DUI, to multi-kilo felony narcotic cases, to murder. From 1994 until 1998, he worked in the Traffic Division, the Narcotics Division, the Juvenile Division, and the Felony Review Division. In each of these positions he tried both misdemeanor and felo

ny bench and jury cases, supervised other attorneys, interviewed defendants and witnesses, and helped prepare criminal cases for trial. However, one of the reasons I decided to go into private practice was that I felt the criminal justice system can be a revolving door. I wasn't able to assist people on a one-on-one level. Through my criminal defense law practice, I have had the ability to change more people's lives than I could as a prosecutor. With two other experienced attorneys, we represent clients in all types of criminal and civil matters in both Illinois Federal and State Courts." -Thomas Glasgow

In addition to criminal charges, we help people who need representation in the area of family law including divorce proceedings and child support. Attorney Stephanie Olsson mindfully represents domestic relations clients throughout the Chicagoland area to reach equitable resolutions to matters that are closest to home. Stephanie Olsson has experience in representing a range of clients from parentage matters to clients with complex dissolution matters such as business valuation, special needs children and high-conflict parenting issues. Attorney Olsson’s background in criminal law assists Ms. Olsson execute an aggressive yet practical approach to your matter.

“Domestic relations matters are incredibly personal to each individual client. It is important to listen to a client, hear his or her goals and objectives for a case, and then guide the client via the litigation process to a resolution that is in the client’s and if applicable, children’s best interests. As a domestic relations attorney, I seek to ensure that my clients understand that each has a voice in his or her case and that voice is an integral piece in guiding a case to a resolution.” - Stephanie Olsson

At Glasgow & Olsson, we realize getting people on the right path toward becoming a good citizen is an important goal of our firm.

STEP GRANTS: INCREASED ENFORCEMENT DOES NOT MEAN AUTOMATIC GUILT

To help combat impaired driving, the state of Illinois uses the Sustained Traffic Enforcement Program (STEP). The program provides funding to local law enforcement agencies to enhance their enforcement efforts with the aim of reducing dangerous driving behaviors, particularly during periods when impaired-driving crashes are more likely to occur.

Still, even though STEP is meant to deter impaired driving, STEP-funded stops have the potential to be constitutionally or procedurally improper. This distinction can have a major impact on one’s DUI case.

If you were pulled over by police and arrested for DUI, it is essential to have an attorney representing you. A DUI conviction can lead to the loss of your driving privileges on top of being incredibly costly. Your attorney will scrutinize the details of your arrest to determine the best defense strategy available, including the legality of your traffic stop or DUI investigation.

The experienced Chicago DUI defense attorneys at Glasgow & Olsson can assist and help you in meeting the challenges of a DUI arrest.

ILLINOIS ARMED VIOLENCE 720 ILCS 5/33A EXPLAINED​

It is important to understand that the state of Illinois punishes individuals who have committed armed violence. The offense is governed primarily under 720 ILCS 5/33A, Article 33A of the Illinois Criminal Code. As such, it is essential to know that armed violence is not simply a charge that alleges you possessed a weapon. Instead, the statute generally connects an alleged weapon possession or discharge during the commission of another felony.

Being charged with Armed Violence in Illinois can expose you to substantial criminal penalties if you are convicted. The extent of your sentence will depend on the following:​

The precise underlying felony being committed
The type of weapon that was involved in the commission of that felony
Whether the firearm was discharged during the felony act
If you have been arrested and charged with armed violence in Illinois, you should immediately seek the assistance and guidance of an experienced attorney. Do not assume that because you did not fire your weapon that this charge will not apply to you. For example, Section 33A-2(a) addresses being armed with a dangerous weapon while committing a qualifying felony, with separate provisions for the actual discharge of your firearm.​

The Chicago armed violence defense attorneys at Glasgow & Olsson can provide you with legal counsel to protect you from suffering the severe consequences of an armed violence conviction. Our team has the background, in-depth knowledge of Illinois criminal laws, and the resources necessary to provide you with the strongest defense possible.​

WHAT IT MEANS TO BE CHARGED WITH RECKLESS DISCHARGE OF A FIREARM IN ILLINOIS

It is incumbent on all gun owners to be responsible with their weapons and follow the federal and state gun laws. Violations of state or federal gun laws can come with serious consequences and repercussions.

​In Illinois, fi****ms offenses are taken very seriously. Reckless Discharge of a Firearm under 720 ILCS 5/24-1.5 is a charge that often surprises people. One of the main reasons is that most people think that legal trouble only comes when someone uses their firearm to willingly hurt or injure another person. It is true that if you use a firearm with intent to harm someone, that is a criminal act. However, in Illinois, if you engage in dangerous behavior with your firearm that puts others at risk, you can be arrested and charged with a crime. Firing a gun recklessly, even if no one is injured, can result in felony charges and long-lasting consequences.

​You may think playing around with your firearm and irresponsibly firing it, without trying to hurt anyone, isn’t that big of a deal. Especially if no one was actually harmed. Well, you will need to think again. This behavior is criminal, and you can be arrested and charged with Reckless Discharge of a Firearm. Prosecutors are known to aggressively pursue firearm charges, even in instances where there was no one hurt.

​In this case, when you have been charged with Reckless Discharge of a Firearm, you should not be under any assumption that serious punishments won’t follow. The reality is that a conviction can lead to prison time, fines, probation, and more.

​You will need an attorney and, in specific, one who has a deep understanding of Illinois gun laws. At Glasgow & Olsson, our Chicago gun defense attorneys can evaluate the evidence in your case, identify weaknesses in the prosecution’s case, negotiate with the prosecutors where appropriate, and protect your constitutional rights throughout the legal process.
