Welcome to the new Sweetnam LLC website. We redesigned the site to make it easier to learn about our firm, understand the cases we handle and get in touch with our team.
Who We Are
Sweetnam LLC is a Chicago-area law firm that represents people who have been harmed by corporate wrongdoing, negligence or carelessness. Our practice is built on one idea: when a business or an individual causes harm, the people affected deserve someone who will stand up for them.
What We Handle
Our firm focuses on several areas of law:
- Consumer fraud and class actions: We represent consumers harmed by unfair or deceptive business practices, including cases brought on behalf of large groups of people affected by the same conduct.
- Privacy violations: We pursue claims for people whose privacy rights were violated by companies that mishandled their personal information.
- Personal injury: We represent people injured in accidents caused by someone else’s negligence.
- Medical malpractice: We help patients and families hold healthcare providers accountable when substandard care causes harm.
