About Me

Over thirty years experience handling appeals before the Oregon Court of Appeals and Oregon Supreme Court in all areas of the law other than criminal.  My practice includes, but is not limited to  cases in the following areas of the law: civil, tort, family law (divorce, dissolution of registered or unregistered domestic partnership, property distribution, spousal support (alimony), custody, parenting time, child support) contract, business law, elder law, animal rights, commercial landlord tenant, land use,  and adminstrative law.  I am very experienced in legal research,  writing lengthy briefs in sometimes very complex matters and effective oral argument to the court.   I pride myself on making sure that my client's story is told to the court persuasively, completely and with the most persuasive legal argument possible.

    I endorse Margaret Lieberan without any qualification. I have known her for 30 years as a fellow attorney and friend. We have represented both aligned and opposing interests in a number of appeals; I have retained her as an expert witness on attorney fees and other appellate matters; and some years back she worked for me on a contract. She is industrious, insightful, and thorough in all appellate matters, and she is unfailingly professional.
