FINRA Suspends David John Taddeo for Undisclosed Private Securities Transactions
David John Taddeo suspended by FINRA for unauthorized private investment sales
According to FINRA records, David John Taddeo (CRD# 1163829), formerly registered at a FINRA member firm in La Mesa, California, was issued an Acceptance, Waiver and Consent (AWC) on December 30, 2025. FINRA found that Taddeo engaged in private securities transactions without disclosing them to his firm, settled customer complaints outside formal channels, and then misrepresented his conduct on compliance questionnaires.
The Securities Violations
FINRA found that Taddeo participated in private securities transactions with three customers involving a total of $255,000 in investments, without providing prior written notice to his member firm. The transactions involved promissory notes issued by a private company.
According to the AWC, Taddeo’s role in facilitating these transactions included introducing the investment opportunity to customers, providing information about the company, and assisting two customers in liquidating existing brokerage account positions at his firm to generate funds for the private investment. Notably, Taddeo did not receive any commission or compensation for his role in directing these investments.
False Compliance Attestations
The regulatory record reveals a pattern of misrepresentation. According to the AWC, Taddeo falsely attested on annual compliance questionnaires that he had not offered, issued, or participated in private securities transactions or promissory notes outside of his firm, and that he understood he could not direct customers and non-customers to investments not approved by his firm. These representations were made despite his active involvement in the undisclosed transactions.
Unauthorized Customer Settlements
The AWC also addressed how Taddeo handled customer complaints. FINRA found that Taddeo settled complaints from two customers who had invested in the private securities transactions, without the knowledge or consent of his firm. Taddeo personally repaid the two customers the full amount of their original investment in the promissory notes, conducting these settlements completely outside the firm’s control and oversight. Taddeo also falsely attested on annual compliance questionnaires that he had not settled customer complaints away from the firm.
The firm discovered the unauthorized settlements and private securities transactions when a third customer submitted a written complaint. This escalation prompted the firm to investigate and ultimately led to the regulatory action.
Suspension and Financial Sanctions
FINRA imposed the following sanctions on Taddeo: a deferred fine of $7,500 and a four-month suspension from association with any FINRA member firm in all capacities. The suspension is in effect from January 5, 2026 through May 4, 2026, effectively barring Taddeo from working in the brokerage industry during this period.
Why This Matters for Retail Investors
A broker’s recommendation that a customer liquidate positions at his firm to fund an outside investment may not be suitable for that investor. When a customer invests money in a private deal recommended by their broker and that investment fails, the customer should file a claim through FINRA’s formal arbitration process. .
Annual compliance questionnaires are the regulatory system’s primary method of discovering undisclosed outside business activities. If a broker checks “no” on the private securities question while actively engaging in undisclosed transactions, this can make it more difficult for regulators to oversee the broker’s activities.
