Mediation Experience


Since 2007 I have received bench referrals and worked as an on-site mediator in several Northern California counties, including: Lake, Mendocino, Sonoma, Marin and San Francisco Superior courts. I was the court appointed civil mediator under contract to the Mendocino Superior court (2011-13); and started a free civil mediation program in the Marin Superior court in 2014 where now all contested civil harassment cases have the opportunity to settle before trial. These court programs honed my skills at resolving sensitive and emotionally-charged cases such as unlawful detainer and restraining order cases (currently over 800 cases in each).  Other areas of experience include: small claims appeals, breach of contract, insurance, construction defect and merchant-consumer, as well as tenant-subtenant, elder abuse, juvenile, workplace violence, neighbor, and HOA disputes. I also regularly mediate grievances related to police conduct as part of the new SF Office of Citizen Complaints (OCC) Mediation Program.


My court mediation work now is limited to the Marin court (average 2-3 cases per week), but I maintain a private practice covering the entire Bay Area including: mediation services (pre-file, pre-trial or post-trial), consulting and training services, other neutral services (such as civil stand-by or property exchanges), and fiduciary services (trustee, estate negotiations). With a background in health, administration, and a 25+ year environmental consulting career, my scientific and professional background makes me a capable neutral expert; able to work with complex technical and legal issues; and provide analysis in cases involving health, environmental, real property, development and resource rights.
