About Oliver
Biography
Throughout my legal career, I have devoted my skill and experience to helping my clients find peace of mind where family interests and finances intersect. I deal in a variety of legal issues ranging from collection defense with the IRS to important family law issues such as Divorce, Custody, Parenting Time, and Child Support. In my work I strive to give my clients and their cases the personal attention they deserve.
I began my career as an attorney for one of Portland’s most respected commercial litigation firms. There I honed my skills on complex litigation, and obtained excellent skills in strategy, negotiation, complex procedure, and research. I now focus my skills on serving individuals facing family law and tax issues.
I am an avid soccer fanatic and can typically be spotted roving the sidelines of any Timbers home match or catching a spot of Premier League action at one of the marvelous soccer pubs in town.
