Helping You Resolve Problems Efficiently

Experience. Integrity. Impartiality.

Looking to avoid the costs and time involved in litigating a dispute in the courts? Need an independent set of eyes to peer review your litigation strategy or monitor your compliance with a consent decree? Let me bring my judgment, integrity, and nearly 40 years of experience as an environmental litigator to assist you.

I am Rob Olian and I started envADR after my recent retirement from Sidley Austin LLP, where I began practicing in 1977. At Sidley, I headed the Chicago Environmental practice group and was co-leader of the firm’s national Environmental practice from 1994 until I retired. I am a Fellow in the American College of Environmental Lawyers and a Board member of the Chicago chapter of the Association for Conflict Resolution, was a member of the N.D. Ill. Trial Bar until retirement, and have been listed in the top tier of Chambers USA’s America’s Leading Lawyers for Business and Best Lawyers in America for the past several years.  Best Lawyers named me 2016 Lawyer of the Year for Chicago Litigation – Environmental and 2017 Lawyer of the Year for Chicago – Environmental.

Professional Background

I joined Sidley Austin in 1977 and began practicing environmental law full-time shortly thereafter. Through the years, my practice moved from RCRA compliance to CERCLA to civil and criminal enforcement and ultimately to environmental tort litigation.

Educational Background

I graduated from Harvard College cum laude in Applied Mathematics (which is actually relevant for allocation matters!) in 1973 and received both my law degree from Harvard Law School and  Masters in Public Policy from Harvard Kennedy School in 1977. I completed the 40-hour Certificate Program in Mediation Skills at Northwestern University in 2016.
