Kevin G. Collimore

I am delighted to join PRISM/Hess Gehris Solutions after a 30-year career as a civil trial attorney and over 20 years as a mediator and arbitrator. Most recently, I was a member of Cullen Collimore Shirley which I co-founded in 2008, after nearly a decade in the litigation department of a storied New Hampshire general practice firm and four years as a department manager investigating and responding to environmental and toxic tort litigation nationwide for one of North America’s most successful claims management firms. I am a member of the National Academy of Distinguished Neutrals. Since 1999, I have facilitated more than 500 court-ordered and private mediations and arbitrations.I was honored to be recognized by Best Lawyers for 2025 in construction law. As a home builder and general contractor in a prior life, I have a special affinity for construction cases (job site injury, contract dispute, construction defect claims, etc.) and maintain my OSHA certification for construction safety. I also continue to stay active in construction through working on our historic home, built in 1763, and a cabin I designed and built by hand on an island in Casco Bay, Maine. I think my background gives me a unique perspective when serving as a mediator and arbitrator, especially in construction matters.

I obtained a bachelor of science degree from Southern New Hampshire University, summa cum laude and valedictorian, and a juris doctorate from Boston University School of Law.

Kevin mediates all types of civil and probate disputes. He has particular expertise in personal injury, construction, municipal, toxic tort, and insurance coverage issues.
