John Prangenberg

Owner of Prangenberg Investigations

Providing Private Investigative Services to Ventura and Santa Barbara Counties, Prangenberg Investigation is a conglomerate of former federal, state, and local law enforcement professionals exceeding over 100 years in combined investigative experience. Prangenberg Investigations specializes in static, dynamic, and undercover surveillance cases. Each surveillance operative has a minimum of ten years of hands-on surveillance experience.

Part of our specialty includes building our surveillance modules and surveillance kits for each unique investigative application in-house. We are patent holders for some of our surveillance equipment. We have self-contained surveillance vehicles at our disposal, which can record continuously for multiple days in any environment without interruption.

We have an excellent track record with our proactive surveillance efforts to date.

At Prangenberg Investigations, we only hire former law enforcement professionals. Many of them have additional military, medical, technical, and judicial backgrounds. Many of our team members are bi-lingual.

Every person is driven to provide the client with the best possible investigation by using a proactive approach and due diligence while maintaining the utmost integrity, morality, and ethics.
