Specifically, a client of Oppenheimer Co. Inc. contested Joseph Monaco’s sales practices, according to a complaint dated April 28, 2026. Allegedly, Monaco engaged in unauthorized transactions during 2024, which the client claimed resulted in a tax liability exceeding $1,000,000. It appears that Monaco allegedly caused the client to experience damages tied to stocks. Therefore, the client sought compensation from Oppenheimer Co. Inc. or Monaco in the amount of $1,000,000 in this matter. The complaint was denied on May 6, 2026.
Also, a client of Morgan Stanley Dean Witter Inc. contested Joseph Monaco’s sales practices by filing NASD Arbitration No. 05-00105.

Steven Graham (CRD 1977736) denies the allegations in a pending customer claim filed on August 11, 2026. The disclosure names Western International Securities as the firm, and the claim involves corporate bonds. No arbitrator has ruled on it. His BrokerCheck report also lists a settled bond dispute and a federal court matter from earlier years.
A claim filed on September 11, 2024 names Thomas Hamlin (CRD 2208505) over a 10% Senior Unsecured Note in iCap Fund III. Every disclosure on his BrokerCheck report involves an iCap private placement and names Somerset Securities as the firm. Each one settled, and a settlement is not an admission of wrongdoing.
Peter Po's most recent settlement came on June 28, 2026, when a corporate bond claim settled for $40,000. Po (CRD 3106974) appears in several settled customer disputes over corporate and high-yield bonds. The disclosures name NI Advisors or California Securities as the firm, and each matter ended in a settlement, not a finding.
