Issues Mark Thorndyke is Trying to Hide from You

$440,000+ Dispute with a Client

Before you start a professional relationship with any wealth advisor, it’s best to check their past. It helps you determine whether they are worth your trust or not. The most effective way to go about this process is to check the FINRA BrokerCheck listing of the advisor. 

It’s a vast database where you can learn about your advisor’s state licenses, certifications, employers, and disputes with clients. Mark Thorndyke’s FINRA BrokerCheck listing shows one legal dispute. 


Did You Know?

The most prominent mark in the American consumer history is the ‘ Dodd-Frank Act’. The Act prevents the risk, ceasing the occurrence of a complete financial crisis. The Act also provides common-sense protection for American families by preventing exploitation from pay-day lenders and mortgage firms.

This dispute occurred in 2011. Here, the client alleged unsuitable investment recommendations and misrepresentation from December 2007 to September 2010. They requested $445,232 in damages and settled the case for $75,000. 

In response to this dispute, Mark said that his firm settled the matter only to avoid the cost of litigation. 

However, this dispute shows that Mark has a history of misrepresentation. Filing a legal dispute against a broker is taxing for the investor as well. So, it’s very rare for an advisor to face a dispute for misrepresentation. 

Be cautious of working with such advisors. Another wealth advisory firm that has a history of misrepresentation is the Gouraige Kaplan Ravinet Team UBS

Putting Clients at Excessive Risk

Mark and his firm charge performance-based fees, a highly notorious practice in the finance industry. This fee structure incentivizes him and his firm to implement high-risk strategies. 

Such strategies are unsuitable for most portfolio types, especially portfolios looking for long-term growth and returns. 

That’s because high-risk strategies tend to fail or generate poor returns the longer they are implemented. But they are capable of showing “fast” growth in the short term. Due to this, the advisor can charge you a hefty performance-based fee for the duration. 

Charging Hidden Fees

A huge risk of working with Mark Thorndyke Merrill Lynch and his firm is that he charges hidden fees. His firm recommends investments that charge 12b-1 fees. This is a promotional fee that companies pay to their firm for marketing their investment products. Also, this is a variable fee so the firm can increase it artificially to charge hidden fees. 

The 12b-1 fee doesn’t reflect any actual value. This fee only increases the cost of the investment without offering any additional benefits. 

Some might think that the investments that charge this fee might offer higher returns. But they are mistaken. 

According to an SEC study, investments that charge a 12b-1 fee offer the same returns as the investments that don’t charge this fee. Investments charging a 12b-1 fee tend to offer poorer ROI because their cost is higher. 

Hence, it would be best to avoid investments that charge this fee.


Mark Thorndyke Merrill Lynch claims to be a skilled wealth advisor who puts his client’s interests ahead of his own. But they are all lies. 

The truth is, the Thorndyke Sheppard Group has multiple shady disclosures which put their clients in problematic situations. It would be best to avoid this firm at all costs if you value your financial security.
