About David W.
David W. Lawler built a legal career that moves between public service and private practice. He practices in Illinois and has kept strong ties to the local community where he lives and works.
Lawler earned a Bachelor of Arts in biology and chemistry from Dominican University in 2006. He went on to study law at Southern Illinois University Carbondale, receiving his J.D. in 2010. Those years framed a shift from science into the law and set the stage for his early public-sector work.
Fresh out of law school, Lawler joined the Williamson County office as an assistant state lawyer in 2010. He handled municipal and county-level responsibilities during that time and worked in the courthouse on behalf of the public interest. Two years later he entered private practice at Lawler Brown Law Office. He became a partner in 2012 and has remained with the firm since, balancing client work and the administrative demands that come with a small law office.
Colleagues and peers see him regularly at bar association events. He has been a member of the Illinois State Bar Association since 2010 and of the Williamson County Bar Association over the same period. He also joined the Illinois Trial Lawyers Association in 2014. Those memberships have provided a steady connection to statewide and local legal networks.
Lawler’s office is based at Lawler Brown Law Office in Marion. The firm’s office sits across from Marion Junior High, a location he has used as a steady home base for client meetings and court preparation. He handles matters that arise under Illinois law and appears in state courts when needed. He maintains a practice that reflects his years in the public sector and his subsequent work in private practice.
As of 2026 he continues to practice at Lawler Brown Law Office in Marion, representing clients in matters brought in Illinois state courts.
