  • Justin Mankin joined Montgomery | Amatuzio in 2017 and became a partner in 2023. His practice focuses on civil litigation, insurance coverage, and strategic risk management, representing clients ranging from Fortune 500 companies and national insurers to regional hotel and restaurant chains, small businesses, and individuals.

    Justin’s experience spans the spectrum of litigation, from general negligence and personal injury matters to catastrophic injury, wrongful death, and commercial trucking accidents. He has defended fetal injury and death claims, civil homicide matters, and carbon monoxide exposure cases, and frequently serves as personal counsel to individuals facing high-exposure and complex liability claims. Justin has also represented more than fifty rideshare operators, including in cases involving multimillion-dollar exposure.

    A substantial portion of Justin’s practice involves representing insurance carriers in coverage matters, UM/UIM disputes, commercial property claims, and statutory bad faith litigation. He regularly advises and defends national insurers in matters involving general liability, professional liability, errors and omissions, and business-owner policies, and has significant experience litigating declaratory judgment actions in both state and federal courts.

    Justin approaches every case with a practical, outcome-driven mindset. Whether through early motion practice, mediation, arbitration, or trial, he works to align litigation strategy with each client’s business objectives, financial considerations, and overall risk exposure.

    He regularly presents to insurance carriers on claims-handling issues and emerging appellate developments and has spoken at law schools on legal issues involving the rideshare and gig economies. Justin also provides pro bono representation to tenants in landlord-tenant disputes and is an active member of the Colorado Defense Lawyers Association.

    Outside the office, Justin enjoys golf, travel, live music, and comedy. He is an avid football and college basketball fan who has traveled to watch his obscure mid-major alma mater play in three consecutive NCAA tournaments. For better or worse, he can quote most episodes of Seinfeld from memory.
