Jonathan LaCour is the founder and CEO of Employees First Labor Law, WIN Trial Lawyers, and LaCour Trial Lawyers — seven California offices, more than $200 million recovered, and a company that is still led from the courtroom. He is also a mediator with AMAJ and an angel investor in operator-led companies.
Employees First Labor Law started with one lawyer, no office, and no staff. A decade later it is three firms and seven offices — grown on purpose, one hire and one courtroom at a time. The founder story →

Pasadena, Irvine, Long Beach, Pomona, Riverside, Bakersfield, and Fresno — the same trial lawyer behind a worker in the Central Valley as in Orange County.

lacour.law ↗Most plaintiffs’ firms are run case by case. Jonathan runs his like a business — systems, accountability, and a culture people want to join — so that the lawyers can spend their time winning. How the firm is built →
The operating idea is simple and unusual for a plaintiffs' firm: run it like a company. Jonathan completed Stanford Graduate School of Business's executive program in leadership and organizational strategy and brought the capstone home — a shift from reactive to proactive case management that now governs how every matter at EFLL is staffed, calendared, and prepared for trial from day one.
Leadership isn't about titles — it's about influence, accountability, and alignment. We have built a culture where excellence is expected, but empathy is required.
Growth has been intentional: a headquarters on South Fair Oaks in Pasadena, then Irvine, Pomona, Riverside, Long Beach, Bakersfield, and Fresno, so that an injured or wrongfully fired worker in the Central Valley has the same trial lawyer behind them as one in Orange County. The firm has doubled in size more than once, and the standard hasn't moved: every case is measured by whether the result changed the client's life.
The firms keep growing, and growth is a people decision. We hire trial lawyers, associates, law clerks, paralegals, case managers, intake specialists, and operators who want to work on the right side of the caption — and who want to get better every year they are here.
Excellence is expected. Empathy is required.
Great companies don't just disrupt markets — they redefine expectations. Jonathan invests in founders who pair innovation with execution discipline, and treats each investment as a partnership: growth systems, leadership coaching, positioning, and preparation for the next round.

Employees First Labor Law · 2025Jonathan LaCour is the founder and CEO of Employees First Labor Law and WIN Trial Lawyers, and founding partner and lead trial counsel of LaCour Trial Lawyers, the firm's class-action practice representing California communities harmed by wildfires, chemical releases, and industrial disasters. He is a trial lawyer known for aggressive litigation and inventive advocacy, and he has led the firms' expansion to seven offices across Southern and Central California while continuing to try and settle high-stakes cases himself.
He began his career on the other side of the table, as in-house counsel to a large manufacturing company, before moving to employment law and founding EFLL. That vantage point — knowing how employers actually make decisions and paper them — still shapes how he builds a case.
He earned his J.D. at Loyola Law School, where he was selected to the Federal Bar Association National Moot Court Team and competed nationally against the country's top law schools. He later completed a certification at the Stanford Graduate School of Business in leadership, organizational strategy, and scaling high-growth teams; his capstone, "Shifting from Reactive to Proactive Case Management Culture," was implemented directly at EFLL.
Every case is more than a file — it's a life, a story, and a promise to deliver justice with honor.
