About me

I handle a broad range of civil litigation and general corporate matters for business entities of all sizes as well as individuals. My practice focuses on commercial litigation, construction and real estate disputes, business torts and shareholder actions, equitable claims (including proceedings for temporary restraining orders, preliminary injunctions, and permanent injunctions), general corporate matters (both for-profit and not-for-profit), employment issues, creditors’ rights and bankruptcy, appellate advocacy, commercial and residential real estate transactions, and estate planning and wealth management. I practice regularly before all federal courts in the Northern District of Illinois as well as the Circuit Court of the Eighteenth Judicial Circuit (DuPage County, Illinois), the Circuit Court of Cook County, Illinois, and all other collar counties immediately surrounding Cook County.

  • Scott Andrew Nehls

    Matt and I previously worked together when he was a partner at my current firm. In my time working with Matt on various matters, I found him to be an exceptionally diligent and well-reasoned attorney. I strongly endorse him.

  • Thomas Keith Mirabile

    I endorse this lawyer. Mr Pfeiffer was opposing counsel on a highly contested adversary case in Bankruptcy Court .He came to the case after the original lawyer withdrew . It was a breath of fresh air as he is highly intelligent ,skilled and trustworthy and a worthy opponent and advocate for his clients . I highly recommend him as an attorney and advocate.
