The firm mourns the passing of Stephen H. Armstrong on April 13, 2022. He was a wonderful friend and colleague to so many of us and will be missed.

Stephen H. Armstrong focuses on environmental law.  Organizations seek him out for help with environmental litigation, site remediation, regulatory and enforcement matters, corporate and real estate transactions and compliance counseling.  In particular, he concentrates his practice on issues related to contaminated properties and has represented utility companies in a variety of lawsuits.  He also counsels extensively on financial reporting and disclosure obligations related to environmental matters.

Mr. Armstrong is of counsel and is a member of the firm’s Environmental and Workplace Health and Safety Law, and Climate and Clean Technology Law Practices.  He speaks frequently on environmental topics, including liability issues associated with property transactions and environmental financial reporting and disclosure obligations.  He is president of the Illinois chapter of the National Brownfield Association and serves on the NBA’s board of directors.

Prior to joining Jenner & Block, Mr. Armstrong served for multiple years as lead environmental counsel for a large diversified energy corporation with a substantial portfolio of former manufactured gas plant (MGP) sites.  In that role, he gained extensive experience in site remediation, environmental litigation, regulatory matters, rate recovery proceedings and environmental financial reporting.
