Private Investigation Services

Most private investigators / private detectives gain their experience investigating insurance matters and remain in that private investigator skill set for the duration of their time in the investigation industry. This is not so with private investigators who work for Lyonswood Investigations and Forensic Group. Because Lyonswood has over thirty years’ investigation experience, Lyonswood’s private investigators all have broad based private investigator competencies gained from both the private and policing / law enforcement sectors.

The word private detective is sometimes used instead of private investigator. Some private investigators are ex-police detectives and some private investigators within the industry call themselves private detectives. Regardless of what a private investigator or private detective calls him or herself, you need to ensure your private investigator does not only have experience in insurance matters or in the police but has experience helping people in the private sector with their unique personal and litigation needs.

Lyonswood Investigations and Forensic Group is one of the only private investigation/private investigator companies that can honestly claim broad based private investigator expertise and back it up through its numerous well documented and listed private investigator case histories, television appearances, T.V. documentaries, well-selected private investigation team members and website and Google Review testimonials.

Testimonials are very important when selecting a private investigator and in the private investigation industry are hard earned and seldom provided because our clients want to maintain their privacy. Usually the clients of a private investigator don’t wish to have their private business published. This is even more reason for you to choose Lyonswood Investigations and Forensic Group as your preferred private investigation/private investigator company as there are thousands more satisfied clients who did not provide testimonials for this very reason.
