Joseph Pierce O'Brien

I have focused on the practice of family law for my entire legal career.  I have opened up my own firm Opal O'Brien LLC where we do things differently than most other law firms.  Our level of service is paramount, and our clients will be able to tell, above all else, that we genuinely care about our clients and getting them the best possible results.  

I practice all areas of family law, including, but not limited to, divorce, paternity, child custody, visitation, removal litigation, grandparent visitation, adoption, child support, maintenance and spousal support formerly known as alimony, orders of protection, enforcing court orders and judgments, guardinaship, and  post-judgment litigation, in DuPage, Kane, Will, Kendall, and Cook County.   I do not generally charge my clients for any travel time or parking related expenses. 

I also handle appeals. I have argued in front of the Second District Court of Appeals and I have drafted numerous briefs at the Appellate Court level.   

I pride myself on keeping my clients informed and in the loop during the divorce process.  Communication is paramount in having a successful attorney-client relationship.  I have substantial experience trying cases and putting on hearings.  I also have the skills to succesfully negotiate cases so as to avoid the expense of a full-blown trial. 

My firm also handles criminal defense cases.  We handle just about every criminal case, including but not limited to domestic battery, DUI, traffic tickets and other felonies.  

I am proud of my recent award of emerging lawyer, a distinction earned by fewer than two percent of all lawyers licensed to practice law in Illinois who are 40 years old or less or practicing 10 years or less. 

Contact me by phone or by email.  My email is and my phone number is.  Consultations are free (on the phone or in person).  I will make myself available to meet with you after normal business hours or on weekends.
