About Us

Our Experience

Our CEO, Kenneth Mains served in Law Enforcement and the United States Marine Corps for a combined 20 years. During those two decades of service he has learned-- above all else-- that integrity and honesty are what the public deserves. He works for the truth in all matters, regardless how complex the case is and regardless who the client is.


After being Honorably discharged from the United States Marine Corps in 1996, Mains put himself through College and obtained a Bachelors Degree in Criminal Justice from Lock Haven University. From there he became a patrol cop with the Williamsport Bureau of Police, Undercover Narcotics Agent for the Lycoming County Drug Task Force, Task Force Officer for the Federal Bureau of Investigations (FBI), Lycoming County Detective and finally the Supervisor of the Lycoming County Pennsylvania Narcotics Unit. 


If that wasn't enough, in 2013, Mains established the world renown, non-profit organization the American Investigative Society of Cold Cases (AISOCC)  to assist law enforcement with their missing persons and unsolved homicides.

We do too and we can help.
