Massachusetts Liquor Liability & Hospitality Expert Witness
Ryan Dahlstrom accepts hospitality and entertainment expert-witness engagements in Massachusetts. 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 Massachusetts. 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 Massachusetts 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 Massachusetts is M.G.L. c. 138, § 69. His opinions address operational standards — staffing, training, supervision, policy and procedure — and do not extend to engineering, toxicology or medical causation.
Massachusetts Law
Negligence built on the service prohibition
Massachusetts does not have a self-executing civil dram shop act. M.G.L. c. 138, § 69 prohibits selling or delivering alcohol on licensed premises to an intoxicated person, and civil claims are framed as negligence built on that prohibition.
Massachusetts courts have long recognised that serving an intoxicated patron can be a foreseeable cause of harm to third parties, including harm caused by drunk driving. Because the claim sounds in negligence, the standard of care for a reasonably prudent licensed operator is directly in issue — which is where industry standards, written policy and training practice do the work.
Licensing authorities can also require liquor liability insurance as a condition of modifying, reinstating or renewing a licence where a licensee has served a minor or an intoxicated person, which produces a regulatory record that often runs alongside the civil case.
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
Massachusetts Venues and Operations
Massachusetts's licensed trade includes Boston's Seaport, Fenway and Faneuil Hall districts, a dense student-adjacent bar economy across Boston and Cambridge, Cape Cod and island seasonal operations, and large stadium and arena event hospitality.
Evidence
What Ryan Reviews in a Massachusetts 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
Massachusetts Engagements
Available for Massachusetts engagements
Ryan Dahlstrom accepts expert-witness engagements in Massachusetts 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.
