Millennium Legal



High-quality representation

Millennium Legal means having an attorney you trust on your side when navigating the system. Don’t risk using an online service offering boilerplate forms without explaining the legal process or customizing services for you. I will find solutions that protect your interests, fight for you, and go above and beyond for you.

Tailored services

I will get to know you and your unique needs to craft the best possible strategy for you. Achieving quality results requires understanding your business and your goals. My focus on providing the right level of legal assistance using the best online tools means low overhead and meaningful savings for my clients.

I invite you to get in touch. Schedule a free consultation up to 30 minutes in person or over the phone.

Sean M. Hoffman is the owner and principal attorney of Millennium Legal. He is a passionate advocate for his clients, and became a lawyer in order to help individuals and small businesses achieve their goals. Helping clients overcome legal obstacles, Sean’s toolkit includes civil litigation, forming businesses and nonprofits, and transactional work such as drafting contracts. In the last four years, Sean has practiced law as a solo attorney, with a non-profit, with a boutique litigation firm, and for political campaigns. He served as Deputy Director of Research for Chicago Mayor Rahm Emanuel’s reelection campaign, where his responsibilities included training and managing the Voter Protection Team of lawyers to ensure the integrity of the election.

Sean earned his JD from Emory University School of Law, where he served on the Faculty Appointments Advisory Committee, Executive Board of the Emory Public Interest Committee, and the Executive Board of the Supreme Court Advocacy Program. He clerked for a U.S. Attorney, the Federal Trade Commission, and twice for the Illinois Attorney General. He is currently active in several charitable organisations, providing pro bono legal services through Lawyers for the Creative Arts and serving on the Advocate Illinois Masonic Medical Center Associate Council charity board. Sean is a native of Chicago where he enjoys cycling along the lakefront and singing with choirs and a cappella groups.
