Seamus O'Connor - Arlington Heights, IL

Associate, Seamus O’Connor, is born and raised in the suburbs of Chicago who earned his bachelor’s degree in psychology from Southern Illinois University at Carbondale in 2019. He went on to attend the University of Illinois at Chicago School of Law, where he earned his Juris Doctor in 2025, graduating with a concentration in Trial Advocacy and Dispute Resolution. In addition to Seamus’ legal studies, his unique academic and vast background in psychology greatly complements his pragmatic approach to legal practice, particularly in matters involving complex interpersonal dynamics and high-conflict litigation. Seamus also demands of himself a mastery of details and organization leading to him being prepared for all situations that court may put before him.

Seamus practices primarily in family law across the Chicagoland area and has experience across the full spectrum of family law matters, from negotiated resolutions in divorce to contested litigation through trial. He approaches each case with the same level of preparation and attention to details, regardless of the size or complexity of the issues involved.

Seamus strives to serve our clients in a way that combines careful counseling, practical negotiation, and, when necessary, zealous advocacy through trial to achieve outcomes that are both effective and sustainable for his clients, always seeking solutions to minimize potential conflict down the line. Seamus has helped clean up many situations for our clients who had different attorneys before seeking our law team to handle their difficult situations.

Seamus’s personal, clinical, and professional experience provides him with a well-rounded perspective on family law disputes. With firsthand experience of the realities of high-conflict divorce, he is particularly attentive to the individualized needs of each client and their family. He works to develop practical solutions tailored to the circumstances of the parties involved, recognizing that family law matters require an approach that is both legally sound and grounded in careful consideration of the individuals and families affected.

Seamus is a valued member of our team who works closely with clients and approaches each matter with care, attention, and a willingness to take on whatever issues arise, whether large or small. Seamus and our founder became friends while Seamus was in his first year of law school and has clerked with our firm prior to joining as counsel in 2025. Seamus is an especially important part of our team and we are so extremely glad he is on our team.
