Securities and Financial Services Representation
Dan represents the firm’s securities and financial services clients in litigation, arbitration, and regulatory enforcement actions and investigations.

Dan primarily represents broker-dealers involved in arbitrated and litigated disputes with customers, registered representatives, and other broker-dealers. His experience includes having primary responsibility for all pre-trial proceedings and coordinating discovery in 250+ arbitrations, state litigation, federal class-action litigation and bankruptcy litigation arising out one of the nation’s largest Ponzi schemes. Dan also represents broker dealers, investment advisers, and financial advisors in regulatory investigations and enforcement matters before the SEC and FINRA.

Dan’s financial services experience also includes representing the firm’s banking clients in mortgage banking cases, including disputes with borrowers regarding application of payments, loan modification claims, and other servicing related issues in state court, federal court, and on appeal. Dan also represents banks and correspondent lenders in mortgage-backed securities litigation arising out of the financial crisis.

In his securities litigation practice, Dan represents publicly traded companies, their officers, and directors in class actions alleging securities fraud and other violations of federal securities laws.

Dan regularly assists with the representation of the firm’s insurance clients in disputes with customers, former salespersons, and class action lawsuits concerning allegations of unlawful sales practices of life insurance producers and in raiding cases.

Appellate Practice
In addition to his securities litigation practice, Dan maintains an active appellate practice that includes representing individuals and businesses in a wide variety of appeals to state and federal courts of appeal. Dan’s appellate practice experience has included representing:

  • executives involved in federal-securities litigation to answer questions certified to the Minnesota Supreme Court regarding the special litigation committees’ authority and the fairness of class-action settlements;
  • banks in disputes with borrowers over purportedly misapplied mortgage payments involving federal statutory claims and state common law claims;
  • preparing amicus curiae briefs discussing the preservation of issues that may be raised when challenging arbitration awards.

Combining his appellate practice and pro bono work, Dan has briefed and argued cases before the Minnesota Supreme Court and the Minnesota Court of Appeals as part of the Minnesota Appellate Public Defender Pro Bono program.

Business and Employment Litigation
Dan also represents a broad array of businesses and employers in litigation matters before state and federal courts and state equal employment agencies. Dan’s representative experience includes defending employers against terminated employees’ allegations of discrimination, sexual harassment, and class actions; and representing a Minnesota county in property-tax litigation in federal court that raised issues of 11th Amendment immunity, availability of tax refunds, and questions of federal exemptions from state taxes.

Dan stays abreast of topics in the securities arena and other developments in the law by writing on current events. He co-authored a white paper entitled “The Efficacy of Securities Arbitration and Proposals for Change,” which was cited by the Wall Street Journal in an article discussing proposals to eliminate mandatory arbitration. In addition, Dan co-authored an article in the William Mitchell Law Review entitled “Standard of Proof to Establish Amount in Controversy When Defending Removal Under the Class Action Fairness Act,” which has been cited by the Ninth Circuit Court of Appeals.

While in law school, Dan served as a staff member and assistant editor of the William Mitchell Law Review. Dan also received awards for best brief and won the oral argument in the Rosalie Wahl Moot Court competition, and in 2005 he represented William Mitchell in the New York Bar Association’s National Moot Court Competition.
