Bradley D. Bonner
Mediator / Arbitrator
Brad’s Story
My idea to pursue a career as a professional mediator developed over a long period of time. In 1992, I joined a civil litigation practice, representing both plaintiffs and defendants in court. Some lawyers choose to take only one side. I always felt working for both plaintiffs and defendants gave me a healthy perspective about what the other side was thinking. It also helped me appreciate there usually are two sides to every story.

Annabel Bonner
Mediation Coordinator
Annabel’s Story
Working remotely from Denver, Annabel is here to help. As the Mediation Coordinator, Annabel is Yellowstone Mediation’s true “point person” from start to finish for contacts with clients, lawyers and all others involved in the mediation process. She meets with clients, fields phone calls, juggles our busy calendar and handles arrangements wherever we travel to mediate cases. Lawyers and other repeat customers know a couple of important things: first, when you call to talk about a mediation case, you’re quite likely going to speak with Annabel; and second, Annabel will handle your every need or request with the highest degree of kindness, helpfulness, professionalism and efficiency.
