Darlene Pasieczny

Representing Clients Nationwide. Call today to speak with a member of the Investor Defender Team. Initial consultations are complimentary and confidential.

Darlene Pasieczny (“Pah-shetch-nee”) leads the Investor Defenders team, with support from our SYK litigators and paralegal staff.

Her wide range of experience and knowledge in the field of securities litigation, elder financial abuse, and FINRA arbitration gives her the edge to help her clients recover investment losses (Watch Video). Based in Portland, Oregon, Darlene is licensed in Oregon and Washington but her FINRA arbitration practice enables her to represent investors nationwide.

Darlene also represents parties in other financial and fiduciary litigation as well as related appellate cases.  These include representing trustees, beneficiaries, and other interested parties in trust and estate disputes such as will contests, undue influence, and nonjudicial amendments to trust terms.  Other type of cases include shareholder rights cases, and elder financial abuse. Sometimes these matter involve financial professionals, and sometimes they unfortunately involve friends, family, trusted caretakers, or other professionals like CPAs and accountants.

Her Investor Defender practice group focuses on investor protection and investment loss recovery for individuals, fiduciaries, groups of investors in court and FINRA arbitration. The Financial Industry Regulatory Authority (FINRA) is the self-regulatory organization that regulates and licenses securities brokerage firms and individual brokers across the country. FINRA arbitration is the main forum in the securities industry for resolution of legal disputes between investors and these industry professionals.

FINRA arbitration is a specialized forum with its own procedural rules – and Darlene knows how to navigate them.

Darlene regularly works with state and federal securities regulators to improve the procedural rules of this forum and advocating for fairness in the securities industry.  Darlene also serves as a FINRA arbitrator.

In addition, Darlene’s years of service work with the Public Investors Advocate Bar Association (PIABA) gives her first-hand knowledge of upcoming FINRA rule changes. PIABA is an international bar association whose members represent investors in disputes with the securities industry. Darlene was awarded the 2017 Outstanding Service Award from PIABA for her dedicated work. She was elected to the PIABA Board of Directors in October, 2017.

She is an advocate for fairness and transparency in the securities industry.

In her law practice, Darlene brings a particular sensitivity to working with the all-too often targets of securities fraud — retirees and women investors from every level of investment experience. Pasieczny (pronounced “Pah-shetch-nee”) is a Polish surname. Her family instilled in her a strong emphasis on education, hard work, and justice for the underrepresented. Darlene is a Top Rated Securities Litigation Attorney by Oregon Super Lawyers, and was selected to the Rising Stars list for 2021.
