A dram shop expert witness is the person who answers the question a jury cannot answer on its own: did this bar, restaurant, or nightclub operate the way a reasonable operator in this industry is required to operate? That question has one reliable answer: the opinion of someone who has actually managed these environments, trained the people who serve alcohol, run the security operation, and made the decisions that define whether an establishment takes its duty of care seriously or does not. I have done all of that for 35 years. Not in a classroom. Not in a research paper. On the floor, behind the bar, and in the operator's seat. That is a different kind of expertise, and in this type of litigation, it is the kind that holds up.
The Role Defined
What a Dram Shop Expert Witness Actually Does
Dram shop litigation, and the bar security and premises liability claims that frequently accompany it, turns on operational facts that fall outside the ordinary knowledge of judges, juries, and often the attorneys trying the case. What does a trained bartender observe when a patron is approaching intoxication? What does a properly run security operation look like in a 500-person nightclub at 1 a.m.? What do industry-standard policies and procedures for alcohol service and incident documentation actually require of a licensed establishment? These are not legal questions. They are operational questions, and they require an expert who has lived them.
A dram shop expert witness provides opinions and testimony on the standard of care applicable to licensed establishments, including bars, restaurants, nightclubs, hotel bars, event venues, and any other entity holding a license to sell or serve alcohol to the public. That testimony may cover the duty to exercise reasonable care in the service of alcohol, the duty to hire, train, and supervise competent employees, the duty to provide adequate security, and the operational practices that either meet or fall below those duties in the specific facts of a case.
What the Engagement Covers
- Case Evaluation: Assessing the operational facts before the complaint is filed or the defense strategy is set, so counsel understands the strengths and gaps in the case from an industry standpoint
- Records Analysis: Reviewing point-of-sale records, training documentation, incident reports, surveillance footage, staffing schedules, and policies and procedures to identify what the evidence operationally supports
- Expert Report: Producing a written opinion that addresses the applicable standard of care, the defendant's conduct relative to that standard, and the operational basis for every conclusion reached
- Discovery Consultation: Advising counsel on which records to request, which deposition questions will expose the operational gaps, and how to frame the standard of care in terms the evidence can support
- Deposition Testimony: Defending the expert opinion under cross-examination with the credibility that comes from having managed these environments directly, not from having studied them from a distance
- Trial Testimony: Explaining complex operational standards and industry practices to a jury in plain, credible terms that connect the defendant's conduct to the real-world consequences of that conduct
The expert witness engagement typically begins well before trial, and its value is greatest when it begins before the complaint is filed. Early involvement allows the expert to shape the factual investigation, identify the most probative records, and assess the viability of the liability theory or the defense strategy from an operational standpoint before significant resources are committed in either direction.
The Critical Distinction
Real-World Experience vs. the Paper Expert: Why It Matters to Your Case
There is a category of expert witness in dram shop and bar security litigation that attorneys encounter regularly and should evaluate carefully. These are experts whose qualifications rest primarily on academic study: they have read the training manuals, reviewed the regulatory frameworks, studied the literature on alcohol service and premises security, and developed opinions about the standard of care without ever having managed a bar, trained a bartender, run a security operation, or been personally responsible for what happens in a licensed venue when something goes wrong. They are credentialed. They can describe what the standards say. But they have never had to apply those standards in a working venue under real conditions, and that gap is consequential.
The problem with a paper expert is not that they are wrong about what the standards require. It is that they cannot speak to how those standards operate in practice, where they break down, and what it actually takes for management to enforce them consistently in a high-volume hospitality environment. That understanding is only available to someone who has been in the operational role. And that is precisely where opposing counsel will go on cross-examination. The questions are not subtle: Have you ever managed a bar? Have you ever trained bartenders to recognize visible intoxication? Have you ever been the person who had to decide whether to call security or call an ambulance? When the answers are no, the jury makes its own assessment of how much that expert's opinion is worth.
In 35 years of operational involvement in the hospitality and entertainment industry, I have answered yes to every one of those questions many times over. That is not a credential in the traditional sense. It is direct, specific, firsthand experience in the exact environment these cases are about. It is what my opinions are built on, and it is what makes those opinions durable when opposing counsel tests them.
"Reading about how a bar is supposed to run and having run one are two very different things. The difference shows up on cross-examination, and juries notice it."

What to Ask Any Expert You Consider Retaining
The Questions That Separate Operational Expertise From Academic Familiarity
When evaluating an expert witness for a dram shop or bar security matter, the most useful questions are not about publications or certifications. They are about what the expert has actually done inside the venues this litigation is about. The answers to those questions determine whether the expert can withstand the cross-examination that opposing counsel will use to undermine the credibility of every opinion offered.
Questions Every Attorney Should Ask Before Retaining a Dram Shop Expert
- Have you personally managed beverage service operations in a licensed venue, and at what volume and venue type? Academic study describes what should happen. Operational experience describes what actually happens and why it sometimes does not.
- Have you written or implemented responsible beverage service training programs for bar or restaurant staff? An expert who has written these programs understands their limitations and their practical application in a way that certification review alone does not provide.
- Have you managed security operations in a high-volume nightlife or entertainment venue? The standard of care for door staff and crowd management in a licensed venue is specific to that environment. General security expertise is not the same thing.
- Have you made real-time decisions about refusing service to a patron, removing a patron from a venue, or calling law enforcement during an active incident? Testimony about what a trained employee should have done carries more weight when the expert has made those same decisions under the same conditions.
- Have you been retained by both plaintiff and defense counsel, and can you explain how your opinion methodology remains consistent regardless of which side retains you? An expert whose opinions reliably favor the retaining party is a liability, not an asset, because experienced opposing counsel will establish that pattern in front of the jury.
- Can you review and analyze surveillance footage and point-of-sale records to form an operationally grounded opinion, rather than relying solely on the parties' written accounts of what occurred? The documentary and video record of a dram shop incident is often more probative than any witness account, and an expert who can read that record fluently adds measurable value.

35 Years of Operational Experience Applied to Every Case
The answers to every question above are grounded in more than three decades of direct operational involvement in the hospitality and entertainment industry. That background is not incidental to the expert witness work. It is the foundation of every opinion, every report, and every hour of deposition and trial testimony.
Retained on Both Sides
Plaintiff and defense counsel retain Ryan Dahlstrom because an objective opinion grounded in operational fact is more valuable, and more durable under cross, than advocacy dressed as expertise.
Background and Qualifications
- Operational Background: 35+ years managing bars, nightclubs, hotel beverage operations, and large-scale entertainment venues across the United States
- Training Documentation: Author of over 1,000 pages of hospitality training manuals, standard operating procedures, and employee handbooks used in active venue operations
- Security Operations: Direct management experience overseeing security operations, use of force protocols, and incident response in high-volume nightlife environments
- Venue Types: Bars, restaurants, nightclubs, hotel bars, gentlemen's clubs, event venues, concert facilities, stadiums, and large-scale festivals and touring productions
- Geographic Scope: Retained by plaintiff and defense counsel in dram shop, bar security, and premises liability matters in jurisdictions across the country
- Video Analysis: Experienced in compiling and analyzing surveillance footage for incident reconstruction, timeline development, and expert opinion support in litigation
That operational background informs every element of the expert witness engagement, from the initial case evaluation through the final day of trial. When I assess whether a bartender knew or should have known that a patron was visibly intoxicated, I am drawing on direct experience training bartenders to make exactly that assessment. When I evaluate whether a venue's security staffing was adequate for its licensed capacity and operational environment, I am drawing on direct experience making those staffing decisions. When I review a venue's written policies and procedures and assess whether they reflect a genuine operational commitment or a paper compliance exercise, I am drawing on direct experience writing and implementing those programs in active venues.
That is the difference between an expert who has studied this industry and an expert who has worked in it. Both may be able to describe what the standard of care requires. Only one can explain, from personal experience, what it actually takes to meet that standard in a working venue, what gets in the way, and how management failures allow the gap between policy and practice to develop. That explanation is what makes expert testimony credible to a jury and resistant to cross-examination.
Working With Me
What an Engagement Looks Like From First Call Through Trial
Every engagement begins with a conversation about the facts of the case and what the available evidence shows from an operational standpoint. That initial consultation allows both counsel and the expert to assess whether the facts support an operationally grounded opinion, what additional records would be most useful, and how the expert's background applies to the specific venue type and incident at issue. There is no obligation from that initial conversation, and it is the most efficient way to determine whether an expert engagement makes sense for the case.
From there, the engagement typically proceeds through a thorough review of all available records, including incident reports, training documentation, point-of-sale data, surveillance footage, staffing records, and the establishment's written policies and procedures. That review produces a written expert report setting out the applicable standard of care, the analysis of the defendant's conduct against that standard, and the operationally grounded basis for every conclusion reached. The report is written to support deposition and trial testimony and to withstand the scrutiny of opposing experts and cross-examination counsel.
I am available for case consultation at any stage of the litigation, from pre-filing evaluation through trial preparation and testimony. The earlier an industry expert is brought into a dram shop or bar security matter, the more value that engagement produces for counsel on either side of the case.
