Premises Liability Expert Witness
Premises liability claims in bars, nightclubs, and hospitality venues frequently involve the same operational failures that drive dram shop liability — inadequate staff training, failure to identify and respond to intoxicated patrons, and breakdowns in security protocol. Ryan Dahlstrom provides expert witness opinions in nightclub and bar premises liability cases for both plaintiff and defense counsel nationwide, drawing on 35 years of direct management experience in high-volume licensed venues.
Premises liability holds a property owner or operator responsible for harm that occurs on their premises when the harm results from the operator’s failure to maintain reasonably safe conditions. In a bar or nightclub context, this typically means failure to provide adequate security, failure to remove violent or intoxicated patrons, failure to maintain safe physical conditions, or failure to respond appropriately to foreseeable threats.
Unlike dram shop liability, which focuses specifically on alcohol service, premises liability in hospitality venues evaluates the full scope of the operator’s duty to protect patrons from harm — including harm caused by other patrons.
The most common premises liability theory in nightclub and bar cases is negligent security. A venue has a duty to provide security staffing and protocols reasonably designed to prevent foreseeable harm. When that duty is breached — through inadequate staffing levels, undertrained personnel, absence of ID verification procedures, failure to enforce capacity limits, or breakdown in incident response — and a patron is injured as a result, the venue may face liability.
Ryan Dahlstrom evaluates security staffing levels against industry standards, reviews use-of-force policies and incident response documentation, and assesses whether the venue’s security operation met the standard expected of a reasonably managed establishment in that market.
Bar fight cases typically involve both premises liability and dram shop theories simultaneously. The plaintiff alleges that the venue’s over-service of alcohol contributed to the altercation, and that the venue’s security failed to prevent or stop the violence once it became foreseeable.
An expert in these cases must be able to address both theories — the alcohol service failures that may have contributed to the patron’s intoxication and aggression, and the security and management failures that allowed the violence to occur or escalate. Ryan Dahlstrom’s background spans both domains, having managed both alcohol service operations and security teams in high-volume nightclub environments.
In many nightclub and bar cases, the plaintiff pursues both a dram shop theory and a premises liability theory in the same action. The dram shop theory targets the alcohol service decisions — did the server recognize and respond to visible intoxication? The premises liability theory targets the security and management response — did the venue take reasonable steps to protect patrons from foreseeable harm?
A single expert with operational experience in both alcohol service management and security operations can address both theories, providing consistent opinions grounded in the same operational framework. This is a significant advantage over engaging separate experts for each theory.
