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

    Justin's litigation experience runs from general negligence and personal injury 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 has served as litigation counsel for more than fifty rideshare operators in matters involving multimillion-dollar claims.

    A significant portion of his practice involves representing insurance companies in UM/UIM claims, commercial property disputes, and statutory bad faith litigation. He regularly advises and defends national carriers across general liability, professional liability, E&O, and business-owner policies, and has substantial experience prosecuting declaratory judgment actions in state and federal courts.

    Justin approaches every matter with an eye toward outcomes and risk-informed strategy. Whether a case calls for early dispositive motions, mediation, arbitration, or trial, he works to align litigation decisions with each client's business objectives or personal circumstances. He finds the most meaningful part of his practice to be helping good people navigate difficult situations.

    He regularly presents to insurance carriers on claims-handling issues and recent appellate developments, and has spoken at law schools on legal topics arising from the rideshare and gig economies. He 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's an avid football and college basketball fan who has followed his obscure mid-major alma mater to three consecutive NCAA tournaments. For better or worse, he can quote most episodes of Seinfeld from memory.
