“Casie is truly a leader and a powerhouse in the area. She has the ability to take super complicated strategies and break them down. She was so impressive and it was amazing to see her in action.”
— Chambers USA 2025
Casie Collignon is a litigator at the forefront of privacy class action defense who serves as co-lead for the firm’s Privacy and Digital Risk Class Action and Litigation team. Class actions in this area are particularly challenging because damages are often pursued based on statutory penalties with no individual damage requirements. Casie views class action defense from a business perspective first and a litigation perspective second in order to determine the most efficient means to attain the results clients desire. Not afraid to employ an aggressive legal strategy when the situation warrants it, she is also open to cooperation between the parties when clients will benefit.
Casie has been ranked in Chambers USA: Privacy and Data Security: Litigation, Nationwide (2023 to 2025) and in The Legal 500 United States Media, Technology and Telecoms: Cyber Law (including data privacy and data protection) (2023 to 2024). In addition, she was named a BTI Client Service All-Star in 2022, a 2021 “Top Litigator” by Law Week Colorado and a 2020 Cybersecurity and Privacy MVP by Law 360. She is also the Digital Assets and Data Management Leader in BakerHostetler's Denver office.
Casie was recognized in the Lex Machina 2026 Class Action Litigation Report as one of the most active attorneys representing defendants in class action filings driven by consumer protection lawsuits tied to data breaches, digital commerce and online accessibility claims from 2023 through 2025. During that same period, BakerHostetler represented defendants in nearly 1,000 new federal class actions across 75 federal district courts—the most of any law firm.
