Choosing A Company

Qualities of a Private Investigator

In some states, it is easy for a person to identify themselves as a Private Investigator but the title should not be the final or only qualification. You should be able to put full trust into the company that you hire and rely on their team to look after your best interest. The right private investigative company can not only handle your situation with professionalism and success, but should have the best team members that you may need including an attorney, doctor, therapist or other specialists. Every Private Investigator should meet these minimum criteria:

  • Licensed
  • Experienced
  • Good Character
  • Record of Testifying in Court
  • Recognizes Human Behavior
  • Explains Process and Fees

Remember that you are hiring a Private Investigator as a first step toward empowering yourself to resolve issues that may prevent you from living at peace or from bringing justice to a situation.


Hiring a Private Investigator

There is often a distinct difference between working with a good private investigator and a bad one. We believe it is important that you know you are working with ethical people that conduct business professionally. The best way to find the right private investigative company is to investigate this yourself. Good sources and starting points include:

  • Sheriff or local deputy at sheriff’s department
  • Investigators working at the District Attorney’s Office
  • Local criminal defense lawyers
  • Your state’s association of private investigators

Identifying good news is always an easy message to deliver but unfortunately there are times when we must deliver unpleasant information. We explain the process to our clients in an effort to best prepare them for the truth our team may uncover. Our company takes pride in being sensitive and caring to our client’s emotions.
