Justin C. Mankin

Justin Mankin joined Montgomery | Amatuzio in 2017 following law school and became a partner in 2023. His practice focuses on civil litigation, risk analysis, and insurance coverage, representing a client base that includes Fortune 500 companies and national insurers, regional hotel chains and restaurants, small businesses, and individuals.

Justin handles matters across the full spectrum of civil litigation, from general negligence and personal injury claims to complex cases involving catastrophic injuries, wrongful death, and trucking accidents. His experience includes defending fetal injury and death claims, civil homicide matters, and carbon monoxide exposure cases. He has also served as counsel for more than fifty rideshare operators, providing strategic defense in multimillion-dollar litigation.

A significant portion of Justin’s practice is devoted to representing insurance companies in uninsured and underinsured motorist (UM/UIM) claims, commercial property disputes, and statutory bad faith matters. He regularly advises and defends national carriers in cases involving general liability, professional liability, errors and omissions, and business-owner policies, and has substantial experience prosecuting declaratory judgment actions in state and federal courts to resolve coverage disputes.

Justin approaches each case with a focus on outcomes and risk-informed strategy. Whether through early dispositive motions, mediation, arbitration, or trial, he works with clients to align litigation decisions with business objectives or personal realities. He finds the most rewarding aspect of his practice to be helping good people navigate difficult situations.

Justin frequently presents to insurance carriers on claims-handling issues, particularly in light of recent appellate decisions, and has spoken at law schools on legal issues arising from the rideshare and gig economies. He also provides pro bono assistance to tenants in landlord-tenant disputes and is an active member of the Colorado Defense Lawyers Association.

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