Mediator Style & Process Preferences
My mediation style is pragmatic, analytical, and results oriented. I approach each case with careful preparation, working to understand the legal issues, business and personal interests, and decision drivers that shape the dispute. I facilitate a process that allows parties to evaluate risk realistically and make informed decisions about resolution. I am comfortable using a range of mediation techniques—facilitative, evaluative, and analytical—depending on what is most effective given the circumstance. Throughout the process, I focus on disciplined reality-testing and clear communication.
Procedurally, I prefer to begin with brief, focused mediation statements and confidential pre-mediation conversations with counsel so that the session itself can concentrate on problem-solving rather than presentations. Joint sessions are used selectively when they will advance understanding or help decision-makers engage constructively, but most of the work typically occurs in confidential caucus where parties can candidly explore options and risks. I actively manage the negotiation process to maintain momentum. My objective is to create a structured but flexible process that enables parties to reach a durable and well-considered resolution.
