Deb Mesle: Why Did Huntleigh Advisor Resign from Merrill Lynch?

Chesterfield, Missouri financial advisor Deb Mesle (CRD# 849766) resigned from a former member firm in connection with alleged rule violations. Financial Industry Regulatory Authority records show that the former Merrill Lynch representative is registered as a broker with Huntleigh Securities Corporation and an advisor with Huntleigh Advisors.

Ms. Mesle’s BrokerCheck report discloses her resignation from Merrill Lynch. Filed in December 2025, the disclosure states that she voluntarily left the firm in connection with allegations that she exercised time and price discretion in customer accounts.

In a statement included with the disclosure, Ms. Mesle defended herself against the allegations. “The termination disclosure filed by Merrill Lynch on 1/9/2026 alleges that I resigned in December 2025 after allegations had been made accusing me of ‘violating investment-related statutes, regulations, rules or industry standards of conduct,’” she wrote. “I deny any allegations that I violated investment-related statutes, regulations, rules or industry standards of conduct. The client did not allege wrongdoing or seek damages, and no regulator or court was involved. I do not believe my clients intended their inquiry to be construed as a complaint. The matter was closed with no action.”
