Background on Matthew Garret Gross (Wells Fargo Advisors, CRD #4763385)
Table of Contents
Matthew Garret Gross is a currently registered broker with Wells Fargo Advisors and Wells Fargo Clearing Services, LLC. According to his recent BrokerCheck report, Gross has passed the Securities Industry Essentials (SIE) exam, the Series 7TO, Series 6, Series 63, and Series 65. His prior industry history includes affiliations with Advised Assets Group, LLC; GWFS Equities, Inc.; UMB Financial Services, Inc.; and others.
What makes this matter urgent for investors is a recent customer dispute that alleges Gross failed to act with the vigilance required by industry rules—potentially exposing a client to preventable losses in connection with a reported scam. Investors should understand both the complaint and the stakes under current industry regulations.
Advisor Red Flags and Complaints: Complete Summary
The primary red flag is reflected in the April 2026 FINRA BrokerCheck disclosure:
- Date Alleged: April 22, 2026
- Nature of Dispute: A client of Matthew Gross alleges he failed to protect the customer after suspicious activity tied to a scam was reported. The activity reportedly began in June 2025 and involved “other miscellaneous” investment products.
- Arbitration Status: The matter is currently pending before FINRA (Docket 26-00929).
- Damages Sought: At least $431,920 in compensatory damages.
Beyond this pending dispute, our rigorous review found:
- No prior customer complaints disclosed in FINRA BrokerCheck
- No regulatory actions, SEC enforcement, or administrative orders
- No civil, criminal, or judicial actions reported publicly
- No external lawsuits, media coverage, or judgments involving Mr. Gross
| Red Flag | Details |
|---|---|
| Failure to protect from suspicious activity | Alleged in a 2026 arbitration. The claimant reports Gross did not act despite a direct warning about scam activity, resulting in claimed losses exceeding $430,000. |
| Pending FINRA Arbitration | Case 26-00929. This matter remains open based on the latest referenced disclosure. Final outcome and liability, if any, have not been determined. |
This lack of historical disclosure may seem reassuring at first glance, but even a single FINRA customer dispute—especially one involving an alleged failure to stop a known scam—raises critical concerns about compliance, professional vigilance, and best practices.
Which Industry Standards and Rules Are at Stake?
Recent allegations against Matthew Gross focus on failure to protect a client after explicit reporting of suspicious account activity. In our experience, this type of misconduct may implicate multiple FINRA and SEC regulations, including:
- FINRA Rule 2010: Requires brokers to observe high standards of commercial honor and just and equitable principles of trade.
- FINRA Rule 2090 (Know Your Customer): Brokers must use reasonable diligence to know the essential facts concerning each customer and the authority of each person acting on the customer’s behalf.
- Regulation Best Interest (Reg BI): Requires broker-dealers making recommendations to retail customers to act in the customer’s best interest at the time of the recommendation, without placing the financial or other interests of the broker-dealer or associated person ahead of the customer’s interests.
A customer’s direct report of a scam may require immediate action, such as internal escalation, investigation, and other protective measures depending on the circumstances and the firm’s supervisory procedures. Failure to act could result in preventable losses to the client and potential liability for the broker and their institution. Our attorneys regularly analyze these failures, working to hold financial advisors and firms accountable and pursue recovery for our clients.
Why These Allegations Matter for Investors in Kansas City and Nationwide
If a financial advisor overlooks or fails to address red-flag complaints from clients, it may signal broader issues with supervision, diligence, or compliance training inside a broker-dealer. A pending claim for more than $431,000 demonstrates how quickly investor losses can mount when action is delayed.
Regulation Best Interest makes clear that an advisor cannot place their own interests—or the firm’s interests—ahead of the retail investor’s interests when making recommendations. When that standard is breached, prompt investigation and potential recovery of losses may be possible through FINRA arbitration or other legal remedies.
