A full time mediator and arbitrator since evolving from litigation to opening the Chicago JAMS/ENDISPUTE office in 1982, Bill's national practice includes more than a thousand complex matters arising in over 40 states and foreign countries.

His construction practice dates from the late 1980s, when parties and design carriers encouraged mediation as an early alternative to arbitration, particularly when all parties were not subject to the same project contract. His experience includes hundreds of construction and related matters in more than 25 states.

The mediations and arbitrations involve the entire range of defect, delay, acceleration, design/engineering, and related insurance coverage and damage allocation issues.

The experience included below describes particular mediations and arbitrations, public and private projects, representative matters from 27 states and an overview of Bill’s approach to ADR, which continues to evolve after 26 years.
