My Passion for Dispute Resolution

I have a passion for dispute resolution. It comes from my heritage – a dad who was a lawyer in the Midwest in the 50’s, 60’s and until he retired at 85 years old in the 90’s. He was a master negotiator but at the same time a supreme diplomat. His best friend – my Godfather – told me that Dad could tell someone to “go to hell” and they thought they received the Congressional Medal of Honor.
