"Jill has a well-earned reputation for settling tough cases. We faced a difficult situation where defendants’ insurance carrier dragged a case out for more than a year of contentious litigation, and then claimed a coverage issue. We tried mediating with someone else and were not able to globally resolve the case. With Jill’s assistance during a remote mediation session, and in multiple follow up calls, we were able to resolve the entire case for far more than the carrier initially offered. By listening to my clients’ frustrations, she was able to persuade them to let go of the personal animus towards the other side and move on. I highly recommend working with her."
