Arizona Dram Shop & Bar Operations Expert Witness
Ryan Dahlstrom accepts hospitality and entertainment expert-witness engagements in Arizona. 35+ years of hands-on experience in bars, restaurants, nightclubs, hotels, live entertainment venues and special events — retained by attorneys representing plaintiffs and defendants.
In short
Ryan Dahlstrom is a hospitality and entertainment industry expert witness who accepts engagements in Arizona. He has more than 35 years of hands-on experience in bars, restaurants, nightclubs, hotels, live entertainment venues and special events, and is retained by attorneys representing plaintiffs and defendants. In Arizona matters he evaluates hospitality and venue operations, alcohol service and overservice, bar and nightclub operations, restaurant operations and management, security operations and negligent security, premises liability, event management, event security, event and stage safety, and surveillance video analysis. The governing framework in Arizona is A.R.S. § 4-311. His opinions address operational standards — staffing, training, supervision, policy and procedure — and do not extend to engineering, toxicology or medical causation.
Arizona Law
"Obviously intoxicated" — statute only
A.R.S. § 4-311 makes a licensee liable where it sold alcohol to a person who was obviously intoxicated or to a minor, that person consumed the alcohol, and the consumption proximately caused the injury.
The statute defines the standard: a person is obviously intoxicated when they are inebriated to the point that physical or mental impairment is obvious to an ordinary observer — physical uncoordination, serious physical dysfunction, slurred speech. It is an observational standard, decided on what was visible in that room.
Arizona narrowed the field further in Torres v. JAI Dining Services (Phoenix), Inc. (Ariz. 2023), which eliminated common-law dram shop actions. The statutory route under § 4-311 is now the route, which places the whole weight of the case on what staff could observe and what the operation required them to do about it.
Statutes and regulatory schemes change, and this is not legal advice. Citations were verified against the state code or controlling decision and the named regulator at the time of writing; counsel should confirm the provision current to the date of loss. Ryan offers opinions on operational standards, not on the law itself.
Hospitality Context
Arizona Venues and Operations
Arizona's licensed trade spans Scottsdale's Old Town entertainment district, Phoenix and Tempe college-adjacent bars, Tucson's 4th Avenue, resort and golf-club food and beverage across the Valley, and a large seasonal pool and day-club operation where heat, hydration and service pace change the intoxication picture materially.
Evidence
What Ryan Reviews in a Arizona Matter
- Service and POS records correlated into an operational timeline.
- Surveillance video across the service period, reviewed for observable indicators and reconciled against records and testimony.
- Training and certification records for the staff actually on shift, measured against the state's server-training scheme.
- Written policy and procedure — and whether practice matched the document.
- Staffing, supervision and deployment at the relevant time, including security posts and ratios against actual occupancy.
- Incident reports and prior-incident history bearing on foreseeability.

Availability
Arizona Engagements
Available for Arizona engagements
Ryan Dahlstrom accepts expert-witness engagements in Arizona and in all 50 states. His CV documents engagements in nine jurisdictions — Texas, Nevada, New Mexico, Illinois, Utah, Washington, California, New York and Kentucky. Where a state is not among those, it means no engagement there is publicly disclosed in the CV; it does not limit availability, and the operational standards at issue in hospitality and entertainment litigation do not change at a state line. What changes is the cause of action available and the evidence that proves it.
