Allegations Against William Tunink

According to FINRA’s BrokerCheck, LPL Financial fired Tunink in September 2025 regarding allegations that he “Failed to disclose and receive prior approval for loans from customers; and settled a customer complaint away from the Firm”.  Generally, advisors cannot borrow money from customers without prior firm approval and under limited circumstances, under FINRA Rule 3270.  The termination was triggered after a customer complained to LPL Financial about a loan not being paid back.

Since then, Bill Tunink has been the subject of a second customer complaint.  The customer alleged that he sold them “Investment Units” and entered into a “Silent Partner Agreement”.  Advisors are not allowed to sell investment products that are not approved by their firm, under FINRA Rule 3280.
