"It was the films, I'm sure, absolutely sure (well OK, I had a little to do with it, but it was the films). Thank you Jeff Alexander / Liberty Investigations - thank you thank you thank you - another example of what using a first rate investigator will do."

LIS is a professional investigative company that specializes in Subrosa Surveillance, but also provides many types of investigative services to the legal and private sector. We are located in the San Fernando Valley, just North of Los Angeles.

All of our investigators are licensed professionals with many years of investigative experience. Many investigative companies employ inexperienced, untrained people for various investigative work such as surveillance. This allows them to pay lower wages, and make a larger profit on your money. (see “Caveat emptor – Let the buyer beware” page, at left)  This is not the case at Liberty Investigative Services. You can rest assured that a professional investigator will be handling your case, from start to finish.

Our investigative reports are professionally written, concise and informative. You will know exactly what occured or was discovered, and will receive video confirming the written reports.

LIS only employs professional, seasoned investigators that are passionate about succeeding with your investigation. We know that your case is important to you, and we take that seriously. We really care about our clients, and we care about maintaining our fine reputation, which motivates us to put forth an extreme effort to be successful with your case. We will investigate your case as aggressively as possible, within the confines of the law. 

If you have any questions, contact us by telephone or email. We have worldwide contacts in all areas of investigations, and will refer you to professionals that specialize in different areas of investigative work.

Thank you for visiting our web site. If you should choose to use our services I can promise that you will receive professionalism, superior effort and a sincere desire to succeed with your case. I truly hope that you will allow us to serve your investigative needs.
