Frank DiMartini: Altitude Capital Advisor Faces Reg D Complaint

A recent complaint against Newport Beach, California financial advisor Frank DiMartini (CRD# 4512897) alleges that he made misrepresentations regarding investment opportunities. Financial Industry Regulatory Authority records show that he is registered as a broker with Altitude Capital Group, having previously been registered with Alexander Capital.

Mr. DiMartini’s BrokerCheck report discloses one civil lawsuit against him. Filed in September 2025 in the Supreme Court of the State of New York, it alleges that he misrepresented a Regulation D private placement, two “PPE deals,” and “a loan transaction.” The pending complaint alleges unspecified damages. In a statement included with the disclosure, Mr. DiMartini defends himself against the allegations. “I categorically deny all allegations made in the referenced lawsuit and intend to vigorously defend myself against these claims,” he writes. “I am confident that the facts will demonstrate that the allegations are without merit.”

A copy of the complaint available via the Supreme Court of the State of New York provides additional detail regarding the allegations. It alleges that he orchestrated “a fraudulent scheme” against the plaintiff, a longtime friend, from 2022 until 2025. “[Mr.] DiMartini made continuous material misrepresentations to Robert that if he entered into various investment transactions, including loan transactions, he ‘could not lose money,’ and would ultimately profit,” the complaint alleges. “The misconduct was not the product of a single failed deal or an isolated misstatement. Rather, the misconduct was the result of a pattern of calculated deception spanning four separate investment transactions, each designed to mislead Plaintiffs into parting with significant sums of money under false pretenses.” It states that the scheme caused damages “in excess of $1.5 million.

According to the Financial Industry Regulatory Authority, Frank DiMartini holds 18 years of securities industry experience. Based in Newport Beach, California, he has been registered as a broker with Altitude Capital Group since 2025. His past registrations include Alexander Capital, Global Emerging Capital Group, National Securities Corporation, First Merger Capital, Gunnallen Financial, National Securities Corporation, and Salomon Grey Financial Corporation. His credentials include the passage of four securities industry qualifying exams: the Securities Industry Essentials Examination, or SIE; the General Securities Representative Examination, or Series 7TO; the General Securities Representative Examination, or Series 7; and the Uniform Securities Agent State Law Examination, or Series 63. He is licensed in New York. (Information current as of October 25, 2025.)
