Thomas R. May, Esq., J.D., M.S., CFI, CFEI

Fire litigation is a complex endeavor involving specialized knowledge that begins with an accurate determination of fire origin and causation. Fire cases often morph into areas including, but not limited to: (1) fire dynamics, (2) forensic engineering, (3) insurance coverage, (4) arson, (5) product liability, (6) subrogation, (7) spoliation, (8) expert witness admissibility and testimony, (9) fire-related research/trends, and (10) NFPA 921 and NFPA 1033-based peer and file reviews. Don’t kid yourself. Very few attorneys possess knowledge or talent in these multifaceted areas of science and law. In these transforming topics, litigation talent and good judgment are simply not enough.

Thomas R. May provides legal counseling/representation/litigation in the areas of fire science, property & casualty insurance, insurance bad faith, Daubert expert witness admissibility/exclusion, and fire codes. He has over 35 years of extensive experience in all facets of the fire service industry, is a licensed attorney, fire scientist, adjunct professor and certified fire investigator and is internationally recognized for his knowledge, experience and involvement in fire/investigations related fields:

  • his fifteen years of employment with the Cleveland (OH) Fire Department (1987 – 2002) includes service on some of the busiest fire companies in the U.S. (ranked top 10 for structure fires – Firehouse Magazine). Frequently ‘bellying down long hallways’ has provided Mr. May with an implicit understanding of fire dynamics and bolsters his considerable experience in the analysis and interpretation of fire and explosion-related evidence;


  • Mr. May has an abundance of formal fire science-related formal education:
      • Cleveland-Marshall College of Law, Cleveland State University J.D., 2008;

      • University of Cincinnati. B.S. cum laude in Fire and Safety Engineering Technology, 2004;
      • University of the State of New York – Excelsior College, B.S. cum laude in Liberal Studies, 2002


  • his specialized fire/forensic training is exceptionally diverse and extensive; if it burns or explodes, Mr. May likely has some knowledge of the subject area. Examples include:
