Justin C. Mankin

Justin Mankin joined Montgomery | Amatuzio in 2017 after graduating from law school 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, entrepreneurs, and individuals.

Justin's experience spans the full 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 lawsuits, 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, often in matters involving multimillion dollar exposure.

A significant portion of Justin's practice involves representing insurance carriers in coverage disputes, UM/UIM actions, commercial property claims, and statutory bad faith litigation. He regularly advises and defends national insurers on issues involving general liability, professional liability, errors and omissions, and businessowners policies, and frequently litigates declaratory judgment actions in state and federal court.

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 objectives, financial considerations, and overall risk profile.

He regularly presents to insurance carriers on claims handling 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 across the country to watch his obscure mid-major alma mater compete in three consecutive NCAA Tournaments. For better or worse, he can quote most episodes of Seinfeld from memory.
