Alexander Lanzman: Oppenheimer Advisor Faces $5mm Complaint

A recent investor complaint against New York, New York financial advisor Alexander Lanzman (CRD# 2878438) alleges that his conduct resulted in seven-figure damages. Financial Industry Regulatory Authority records show that he is registered as a broker and an investment advisor with Oppenheimer.

Mr. Lanzman’s BrokerCheck report discloses one recent investor complaint. Filed in July 2026, it alleges that as a representative of Oppenheimer, he charged excessive fees, violated FINRA and federal securities rules, and failed to disclose facts in connection with “mutual fund purchases, annuity transactions and hedge fund sales.” The pending complaint alleges damages of $5 million.

In comments included with the complaint’s disclosure, Mr. Lanzman defends himself against the allegations. “I at all times conducted myself in an appropriate and professional manner. I deny all allegations of wrongdoing,” he states, “and intend to vigorously defend myself against the false, unwarranted and unsubstantiated allegations.”

Investors should be aware that FINRA rules forbid brokers from misrepresenting or omitting material facts relating to the investments and strategies they recommend to their clients. FINRA Rule 2020 states specifically that no broker shall “effect any transaction in, or induce the purchase or sale of, any security by means of any manipulative, deceptive or other fraudulent device or contrivance.” Brokers who make misrepresentations regarding their investment recommendations may cause their clients to purchase unsuitable products, in violation of FINRA Rule 2111. This rule provides that brokers and broker-dealer firms must “have a reasonable basis to believe that a recommended transaction or investment strategy involving a security or securities is suitable for the customer, based on the information obtained through the reasonable diligence of the member or associated person to ascertain the customer’s investment profile.” Brokers who lack this reasonable basis, or who otherwise recommend investments and/or strategies that aren’t suitable for their customers, are considered to have violated Rule 2111 and may be liable for damages in the event of losses.

According to the Financial Industry Regulatory Authority, Alexander Lanzman holds 29 years of securities industry experience. Based in New York, New York, he has been registered as a broker and an investment advisor with Oppenheimer since 2003 and 2010, respectively. His past registrations include CIBC World Markets and PFS Investments. His credentials include the passage of six securities industry qualifying exams: the Securities Industry Essentials Examination, or SIE; the Futures Managed Funds Examination, or Series 31; the General Securities Representative Examination, or Series 7; the Investment Company Products/Variable Contracts Representative Examination, or Series 6; the Uniform Investment Adviser Law Examination, or Series 65; and the Uniform Securities Agent State Law Examination, or Series 63. He holds 11 state licenses. (Information current as of August 25, 2026.)
