Dennis has a broad background in litigation, fiduciary appointments, and regulatory compliance.He has tried cases in state and federal courts, handled appeals, appeared in bankruptcy courts, pursued arbitrations, defended administrative proceedings and brought foreign actions.

His early practice centered on personal injury defense and insurance coverage disputes, and later expanded to include commercial and bankruptcy-related cases.Twelve years ago, he began handling SEC enforcement receiverships.The cases have included oil and gas ponzi schemes, Internet-based scams, prime bank schemes, life settlement offerings, and currency trading frauds.This work grew to include Chapter 11 Trustee appointments, as well as FTC consumer and TSSB securities enforcement receiverships, and finally expanded into state court commercial cases and expert witness testimony.This work requires interfacing with parallel criminal enforcement efforts initiated by the FBI, IRS, USPS, and DOJ, and led to the firm' s participation in founding a foreign asset recovery network (FraudNet) and a national association of federal equity receivers (NAFER).

His work with government agencies has, most recently, led to the firm' s greater expansion into handling regulatory matters, including parallel criminal investigations, in the areas of securities, banking and Medicare.His practice continues to include litigation matters in the areas of fair housing, securities fraud, and commercial disputes.Alongside, Dennis coordinates pro bono matters for the firm and participates in Dallas charitable endeavors, including serving as a founding board member of an inner-city legal clinic.
