Jack is a seasoned litigator with experience representing clients in high-stakes commercial disputes in state and federal courts throughout the country, as well as in arbitration. Class action defense represents a cornerstone of Jack's practice — he co-chairs the firm's National Class Action and Mass Arbitration Group and has built an impressive track record of success defending many of the country's largest companies against consumer class actions and mass arbitration campaigns.
Jack has successfully defended over 100 class actions across a wide spectrum of legal issues, including cases involving right of publicity claims, Fair Credit Reporting Act (FCRA) violations, tenant and consumer background-screening statutes, data privacy and wiretapping claims, telemarketing and directory statutes, wage-and-hour disputes, tribal lending matters, securities litigation, and consumer fraud allegations. He also has substantial experience defending mass arbitration campaigns — the increasingly common alternative to class litigation in which plaintiffs' firms file hundreds or thousands of individual arbitration demands — including negotiating and structuring efficient, cost-effective resolutions on behalf of clients facing claimant volumes that would otherwise overwhelm traditional arbitration processes.
Jack understands that each case presents unique dynamics and, as a result, he is careful to tailor the defense to best fit the case and achieve the right outcome as efficiently as possible. In every matter, Jack works to develop factual and legal angles that have not previously been exploited, while remaining keenly aware of the economics of these lawsuits and working in parallel to develop creative solutions that work for both sides.
His work in this area has earned him recognition on the Benchmark Litigation 40 & Under List in 2025 and as a Lawdragon 500 "Next Generation" Class Action Defense attorney in both 2023 and 2024, along with multiple recognitions in Law.com's "Litigator of the Week" column.
Outside the office, Jack enjoys spending time outdoors with his three young children, surfing, spearfishing, and camping.
