Dan Seidman works out of Seidman Margulis & Fairman’s Belleville and St. Louis offices, practices in both Illinois and Missouri, and is licensed in state and federal court.  He has tried numerous jury trials to winning verdict, and has secured countless favorable results for clients through trial, negotiation, mediation, and arbitration.  Dan is also an adjunct professor, each year teaching two courses, Tort Law and Civil Litigation, for the Legal Studies for Paralegals program at St. Louis Community College – Meramec.

Dan worked at Seidman Law during summers in high school.  He became interested in following in his father’s footsteps as a Chicago personal injury lawyer when he observed is dad, Steve Seidman, win a difficult jury trial for a client whose life had been seriously affected by negligence.  Dan grew up in Northern Illinois, but fell in love with St. Louis while attending Washington University in St. Louis.

Dan attended the University of Michigan Law School, where he earned a merit-based scholarship and graduated with honors.  While at Michigan Law School, Dan focused on his trial skills and worked with the ACLU of Michigan, advocating for non-violent parolees whose harsh parole conditions did not allow them to see their loved ones.  During law school Dan also worked as an extern for Judge Michael J. Reagan, with the U.S. District Court for the Southern District of Illinois.

He is married with three kids, all boys. His favorite thing is be outdoors with the family.  He has been known to break out the telescope on particularly starry nights.

Client approach:

“I try to treat clients the way I would like to be treated.  Therefore, I try to be as transparent, easy to reach, and communicative as can be.  I thoroughly investigate and advocate for each case, giving each one the time and thought necessary and beyond, no matter the “size” of the case.”
