Since 2007, the Financial Industry Regulatory Authority, the industry body that oversees broker-dealers, has
fined Detwiler over $250,000 and has cited it for several compliance violations over the past decade.
In December 2011, FINRA sanctioned Detwiler for failing to properly supervise its employees and for allowing its brokers to make more trades than necessary in clients' accounts to boost commissions during a period between 2006 and 2009.
In 2007, the firm, which was then called Detwiler Mitchell Fenton & Graves, settled administrative proceedings that the SEC brought against it for failing to supervise Bradford Bleidt, a former employee who had been simultaneously
running a $30 million Ponzi scheme.
