About Us


After spending the last six years as a Police Officer chasing criminals, I am now passionately committed to helping people in the private sector.   As an armed Private Investigator,  I am tenacious and tireless in my investigations. I have extensive history with investigating Identity thefts and credit card frauds, and understand how violating these crimes can be to people.

I will leave no stone unturned proving or disproving marital infidelity. Shadowing, surveillance, and observing  behavior are just a few tools I use while investigating cheating spouses. There are many nasty faces to the infidelity monster and choosing the right lawyer and understanding divorce/family law are also equally important to this process.

I am tired of seeing  rampant sexual harassment in the workplace, and companies  that normalize and excuse this predatory behavior.  I will investigate these claims and uncover the truth, regardless of who the alleged violator is. 

I am sick of watching high profile people pass supposed "extensive" background checks, only to find out later that they are a danger to the public or our children.  My background checks  will be extensive, thorough, and complete.

I am done with victims being re-victimized.  Know your lawyer, know the court system, and know what path is best for you and your situation!

I will always stand up for what's right, regardless of the opponent. 

Below is a list of services I provide in the investigation world, and the security services I provide that are so critically important in this ever changing volatile society of ours.

Stay safe and always be aware of your surroundings!
