Dennis began his career as an associate, and then partner, at Seyfarth Shaw LLP, where he also served as the Chair of the Houston office's Labor and Employment Section.

He has been lead or co-counsel on many high-profile matters, including several “bet-the-company cases. Dennis regularly advises clients on compensation issues, including exempt-status classifications, bonus and commission plans, day-rate plans, travel pay, training pay, per diem pay, and pre- and post-shift activities.
