Mr. Stubblefield is a partner of the firm.  He is in charge of its Orange County office.  He brings over 41 years’ experience in representing clients in securities enforcement, compliance and litigation matters.  He is one of just a handful of attorneys nationwide with substantial experience in all three sectors important to this practice area: the regulators (SEC Enforcement), in house (most recently as General Counsel of three AIG broker-dealers), and in private practice (with small, medium and large law firms).  His practice focuses on securities enforcement defense/internal investigations, and securities litigation and arbitration. 

Mr. Stubblefield has substantial experience, and success, in the defense of SEC and Finra investigations and enforcement matters.  Many of these matters have arisen in crisis management situations, for example with parallel civil and/or criminal proceedings and related regulatory issues, such as the pendency of broker-dealer membership applications or key registered representative compliance issues.

Mr. Stubblefield’s investigative experience includes handling numerous matters at the SEC, and various corporate internal investigations focused on securities and broker-dealer compliance, including short-selling, over-concentration in customer accounts and selling away/outside business activities of registered representatives.  He also has experience in employment-related investigations, particularly sexual harassment.

He has extensive experience in litigation and arbitration.  In addition to the litigation he handled at the SEC, Mr. Stubblefield has deep and broad experience in various types of securities litigation and arbitration, particularly the defense of broker-dealers and registered representatives in NASD (now Finra) arbitration.  He has represented promoters, investment advisers, investors, and officers and directors in various securities litigation matters.  He also has a broad background in other civil and business litigation.

During his career, Mr. Stubblefield has handled a wide variety of legal matters on behalf of broker-dealers, emphasizing the defense of customer-broker arbitrations, and regulatory/enforcement defense of firms and registered representatives.   As General Counsel of three AIG firms, Mr. Stubblefield was in charge of all legal functions of the respective firms, including management of outside counsel.  He has particularly extensive experience representing independent contractor firms.

Mr. Stubblefield’s experience also includes handling various compliance and risk management assignments on behalf of broker-dealers and investment advisers, and their representatives.  He was in charge of all compliance functions as CCO of two of the AIG firms, and supervised and/or participated in major projects such as revamping of major policies, procedures, forms and contracts.  In private practice, he has handled various compliance and risk management projects ranging from review of advertising and radio scripts of a broker-dealer OSJ to counseling an investment adviser of two private funds regarding steps necessary to be prepared for an imminent SEC subpoena, and related issues.

Mr. Stubblefield is particularly well-suited to provide accurate evaluation of securities claims and regulatory threats by virtue of his experience as both a mediator and expert witness.  He has mediated over 130 customer-broker and industry disputes, and has served as an expert witness on over a dozen matters, including broker-dealer suitability, due diligence, compliance and failure to supervise matters.

He has extensive experience, as lawyer, expert witness, and mediator, in matters involving alternative investments, including Tenant-in-Common (TIC)/Delaware Statutory Trust (DST) interests, and various other forms of private placements.  As lawyer, he has counseled broker-dealers in connection with the retail offer and sales of TICs and other non-conventional products such as forward contracts, including the drafting of ancillary disclosure documents designed to provide enhanced, simplified disclosure of material risks. 

Mr. Stubblefield brings a proactive, creative, common-sense approach to solving regulatory, enforcement, compliance and litigation issues on behalf of his clients, emphasizing, whenever possible, full, transparent cooperation with key regulators, and employing effective use of long-standing professional relationships to enhance client value and outcomes.

Mr. Stubblefield is a member of the California Bar.  He was formerly a Finra mediator and an NASD arbitrator.  He served an Adjunct Professor of Law at Western State College of Law (Fullerton/Irvine, CA) from 2013 to 2016, where he taught Securities Regulation (3 units) and Business Law Ethics (1 unit). He will be teaching a 2-unit Business Law Ethics class at Lewis & Clark Law School in Portland, Oregon, commencing Fall semester 2018.  He regularly presents and writes on various business/legal topics, particularly concerning securities regulation, broker-dealer compliance and supervision, and investment-related arbitration and mediation.
