Glenn Ngo Barred by FINRA Over Refusal to Cooperate

Brokers are expected to act in their clients’ best interests, offering transparent, lawful and trustworthy financial guidance. When those standards are ignored, investors may face significant financial harm.

Glenn Ngo (CRD#: 7200876), formerly registered with Park Avenue Securities LLC in San Diego, California, has been permanently barred from associating with any Financial Industry Regulatory Authority (FINRA) member. The sanction stems from Ngo’s refusal to cooperate with FINRA’s investigation into whether he participated in an unapproved private securities transaction (FINRA Case #2024081737401).

Sonn Law Group is currently investigating claims involving Ngo’s conduct. Investors who believe they may have been harmed are encouraged to contact the firm for a free, confidential consultation.

FINRA Disciplinary Action Against Glenn Ngo

On March 4, 2025, FINRA issued a Letter of Acceptance, Waiver, and Consent (AWC) stating that Ngo violated FINRA Rules 8210 and 2010, which require brokers to cooperate with regulatory investigations and uphold high standards of commercial honor. Ngo consented to the sanctions without admitting or denying the findings.

According to FINRA:

“Ngo refused to produce information and documents requested by FINRA in connection with its investigation into whether he had participated in a potential private securities transaction away from his member firm.”

As a result, Ngo was barred from associating with any FINRA member in all capacities. 

Employment and Licensing Background

Ngo first registered with FINRA in February 2022. He most recently worked as a registered representative at Park Avenue Securities LLC from March 2023 to March 2025. Before that, he was affiliated with Northwestern Mutual Investment Services, LLC in Carlsbad, CA.

Ngo passed the Series 6, Series 63 and Securities Industry Essentials (SIE) exams but held no principal or supervisory licenses. As of now, he is no longer registered with any FINRA member.

The Risks of Unapproved Private Securities Transactions

Private securities transactions, also known as selling away, occur when a broker facilitates the sale of an investment outside the scope of their registered firm, often without the firm’s knowledge or approval. These types of transactions are strictly regulated because they bypass the oversight meant to protect investors.

Without proper vetting, these off-book deals can involve speculative or fraudulent investments that carry high levels of risk. They may lack essential disclosures, provide little to no liquidity and leave investors with few avenues for recourse if something goes wrong. In many cases, the investment itself is difficult to understand or evaluate, making it hard for investors to make informed decisions.

FINRA Rule 3280 prohibits brokers from engaging in private securities transactions without giving written notice to and obtaining written approval from their employer firm. When brokers ignore this rule, they not only violate industry standards but also jeopardize the financial security of their clients.

Red Flags That May Warrant Legal Review

While not every investment loss is the result of misconduct, certain warning signs may indicate that a broker acted improperly or failed to follow regulatory requirements. If you worked with Glenn Ngo or were involved in any investment he recommended, be on the lookout for the following red flags:

• You were offered an investment opportunity outside of a formal brokerage setting.
• You were told the investment was “safe,” “guaranteed,” or “high return” with little risk explanation.
• You received limited or unclear documentation about where your money was going.
• You had trouble reaching your advisor or getting consistent updates about the investment.
• You’ve been notified of a regulatory action, arbitration or legal claim involving your advisor.

These signs often point to a broader pattern of misconduct that could justify a legal claim and potential recovery of your losses.
