Diane Veenendaal: UBS Advisor Faced $5mm Investor Complaint

Brookfield, Wisconsin financial advisor Diane Veenendaal (CRD# 1143233) allegedly failed to act in her customer’s best interest, according to a recent, denied investor complaint. Financial Industry Regulatory Authority records show that she is registered as a broker and an investment advisor with UBS Financial Services.

Ms. Veenendaal’s BrokerCheck report discloses one investor complaint. Filed in October 2025, it alleged that as a representative of UBS Financial Services, she did not act in the customer’s best interest “by allowing fraudulent credit card charges and checks to be made from the account.” The complaint alleged damages of $5 million and was denied by the firm.

The Financial Industry Regulatory Authority maintains numerous rules and standards that brokers must follow. One such rule is the suitability rule, which holds that brokers must “have a reasonable basis to believe” their investment recommendations are appropriate for their customers. As outlined in FINRA Rule 2111, and later Regulation Best Interest, brokers determine an investment’s suitability by evaluating “information obtained through reasonable diligence of the firm or associated person to ascertain the customer’s investment profile.” An investor’s profile includes such information as their age, income, net worth, and risk tolerance. The recommendation of unsuitable investments can lead to potentially significant losses for the customer.

According to the Financial Industry Regulatory Authority, Diane Veenendaal holds 40 years of securities industry experience. Based in Brookfield, Wisconsin, she has been registered as a broker and an investment advisor with UBS Financial Services since 1993 and 1996, respectively. Her past registrations include Everen Securities and Blunt Ellis & Loewi. Her credentials include the passage of four securities industry qualifying exams: the Securities Industry Essentials Examination, or SIE; the Uniform Combined State Law Examination, or Series 66; the Uniform Securities Agent State Law Examination, or Series 63; and the General Securities Representative Examination, or Series 7. She is licensed in California, Colorado, Florida, Georgia, Hawaii, Idaho, Illinois, Indiana, Massachusetts, Minnesota, New Jersey, South Carolina, Tennessee, Texas, Virginia, Washington, and Wisconsin.
