About Jeffrey Trissell

Mr. Trissell is an accomplished civil litigator with numerous wins in both state and federal court. The majority of his practice is in high-profile constitutional law cases and in pre-trial, post-trial, and appellate briefing.

At the trial level, he has successfully moved for or opposed summary judgment on numerous occasions, in his practice representing both plaintiffs and defendants. His motion experience runs the gamut from motions for recusal (of both counsel and judicial officers), anti-SLAPP motions, motions to vacate judgments, motions for attorneys’ fees (where he has received seven figure awards), motions for preliminary and permanent injunctive relief, pre- and post-trial motions for judgement as a matter of law, and motions for sanctions.
