“I am a professional mediator and arbitrator. Before choosing a mediator, advocates need to know the neutral they select will treat their clients with dignity and respect. Advocates need a mediator who will listen. I ask questions. I work hard to find workable resolutions. Litigation is expensive. For that reason, I take my responsibility as a mediator seriously.
I want to help you resolve your disputes. I look forward to your call.”
