About Us

THG Consultants provides consulting services, forensic evaluations, and expert witness testimony. Our clients are organizations seeking solutions for cybersecurity and premises security; property owners/managers looking for strategies for security-related litigation avoidance; attorneys who are involved in premises liability litigation (inadequate/negligent security) requiring the services of consulting and testifying experts. 

Our flagship business, founded by John Harris, provides premises security risk assessments to determine appropriate physical security measures and programs to comply with security industry best practices. For more than 20 years our firm has provided premises security consulting to commercial property owners and managers, risk managers and attorneys.  

Our forensic practice is concentrated in the areas of inadequate/negligent security and negligent hiring, retention and supervision involving assaults, rapes and other violent crimes causing catastrophic injury, or wrongful death at apartments, bars and nightclubs, office buildings, hotels, malls, parking lots, resort properties and other commercial properties. 

Through relationships developed while conducting over 1200 forensic evaluations, we are frequently asked to assist in locating consulting and testifying experts for areas of litigation in addition to inadequate/negligent security. With confidence in our approach to our forensic practice, we have recently expanded with the vision to provide our clients with the same level of integrity, competence, and reliability by affiliating subject matter experts in the areas of cybersecurity and publicly traded securities.  

We are a veteran/woman owned business comprised of consultants/testifying experts who have spent their careers building expertise in their respective fields.

What We Bring to Litigation

We know the key to successful litigation at trial is a confident jury. An expert witness can make or break your case. Every jury member needs to believe that the expert witness is credible and speaking from years of experience and knowledge in his field. The expert witness must be able to distill complex information and explain it in a way the jury can understand.

We provide our clients with honest assessments of the facts and circumstances during litigation. The premises liability arm of our firm has conducted evaluations of premises liability matters of commercial properties in 43 states as well in Puerto Rico, The Virgin Islands and Colombia, South America. We leverage a body of knowledge acquired over 35+ year business careers to inform our clients of all aspects of the issues involved in liability claims.
