Amir is a partner in our Portland office. His practice is focused on litigating and arbitrating commercial disputes in a wide variety of professional liability matters.

From 2000 on, Amir has had substantial experience in securities and investment related matters. He has defended broker-dealers, registered representatives, investment advisors, insurance agents and agencies, issuers, and other professionals in state and federal courts, as well as FINRA arbitrations.  He has represented broker-dealers and Respondent firms in FINRA arbitrations in over a dozen states including, California, Oregon, Washington, Arizona, New York, Illinois, Colorado, Florida, South Dakota, Nebraska and Kansas, and has recently represented several broker-dealers in multi-claimant multi-product complex arbitrations involving selling away, alleged concentration, private placements and alternative investments, like hedge funds, and oil and gas partnerships. Amir also maintains an active regulatory practice representing firms and representatives in investigations initiated by FINRA, the SEC, and state regulatory agencies. He has handled regulatory investigations concerning a variety of alleged conduct, including conflicts of interest, suitability, unauthorized trading, fraud, excessive markups, and failure to conduct adequate due diligence. He has also been retained by firms to assist them when they believe that such investigations are likely to occur, and assists these clients in conducting internal investigations in anticipation of regulatory investigations or disclosures. Amir regularly lectures on developments concerning the securities industry and has provided risk management seminars to several broker-dealer firms as part of their annual compliance and sales conferences.

Amir has also been retained on a variety of professional liability claims and represents or has represented law firms, third party administrators, accountants, custodians, and other professionals in lawsuits or regulatory matters in Washington, Oregon, California and Montana.  For example, Amir and his California colleagues represent: a law firm in a $3 million claim for alleged malpractice stemming from an underlying construction defect claim; an account administrator in an action stemming from a cyber breach; a federal bankruptcy trustee alleged to have acted outside his administrative duties; and a successful real estate developer sued under Oregon’s securities statutes.
