Why Hire A Private Investigator?

Locating People

We are experienced in finding old friends, natural parents, loved ones, those evading lawful legal due process, or others whom you may be missing. Using a private investigator avoids hours spent just to reach frustrating dead-ends. Our location methods are sound, efficient, and economical. Let us help you locate the person you seek.

Obtain a Professional Factual Investigative Report

We provide straight-forward, professional reports of our investigation findings and analyses which are used by clients and their attorneys to help win their court cases.

Conduct a Background Check

Before entering into a contract with anyone, whether an employee, business partner, tenant, or potential significant other, it is prudent to obtain a criminal and civil background check including a credit report. Our background investigations will help you in making good decisions and avoiding future problems in your dealings with others.

Verify Infidelity

During a time when professionalism and compassion are most needed, we help clients and divorce attorneys establish facts for family court proceedings. We discretely and thoroughly gather information that proves beneficial – or even crucial - to the case.

Peace of Mind

Whether related to personal security, employee interviews, surveillance for fraud detection, fact-finding for a custody dispute, or other troubling issues, we are able to verify or disprove a concerning question you may have in your private or business life, allowing you to move forward without doubt.
