Did You Lose Money With Jeffrey D. Mann As Your Stockbroker?
Jeffrey D. Mann is the subject of several customer disputes involving oil and gas and direct participation program investments.
A civil lawsuit filed in November 2025 (Case No. DC-25-21026) in the 134th Judicial District Court, Dallas County, Texas, alleges misconduct tied to oil and gas investment transactions. The complaint claims that investors suffered losses related to interests in Oklahoma-based drilling prospects known as “Clearview” and “6 Shooter.” The suit names Jeffrey Mann as well as Hill Country Exploration as defendants. While the wells were drilled and have produced, the returns are disappointing to the investors resulting in this pending litigation. Damages of $1 million are sought.
Earlier in his career, in March 2011, a customer alleged that Mann recommended unsuitable investments in oil and gas direct participation programs between 2006 and 2008. The case was resolved through mediation and settled for approximately $14,999.
