WELCOME

Welcome to Alpine Investigations. We are a full service private investigation and security guard company, proudly serving the residents of Long Island.


Professional private investigators are in the information business. We can get the information that you need in order to make informed decisions. What you don't know can hurt you, your family, and your business.


Most people do not have the time, tools, or skills to conduct their own investigations. Remember, the private investigations industry is regulated by law in New York State. Always use a licensed, professional private investigator for all of your investigation needs.
