In short
Ryan Dahlstrom is a hospitality and entertainment industry expert witness who accepts engagements in New Hampshire. 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 New Hampshire 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 New Hampshire is N.H. Rev. Stat. Ann. ch. 507-F. His opinions address operational standards — staffing, training, supervision, policy and procedure — and do not extend to engineering, toxicology or medical causation.
New Hampshire Law
Comprehensive statutory liability chapter
New Hampshire's liquor liability scheme is set out in RSA chapter 507-F. It applies to any person licensed or required to be licensed under the state liquor law, and to their employees.
The chapter is a comprehensive statutory framework rather than a single liability section — it addresses the standards of conduct that give rise to liability, defences available to a licensee, and the procedural requirements a claimant must meet. Counsel practising outside New Hampshire should read the chapter as a whole rather than isolating a single provision.
Because the scheme is statutory and self-contained, a licensee's compliance posture — training, written policy, supervision and documentation — is measured against the chapter's own standards rather than against a general negligence yardstick.
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

Availability
New Hampshire Engagements
Available for New Hampshire engagements
Ryan Dahlstrom accepts expert-witness engagements in New Hampshire 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.
