Mr. Thomas Geisler founded blue Chameleon Investigations. Owning and operating his own Private Investigation Agency was something that Tom always wanted to do. He proudly served his community and retired as a Detective from the Charlotte Mecklenburg Police Department after serving for nearly 30 years. Retirement didn’t last long for this Detective. It was a foreign feeling to him and it became clear, it was the right time to start his own Private Investigation Agency. He soon looked into getting his P.I. License. These were the beginning phases before his personal vision came to fruition. The name Blue Chameleon Investigations (BCI) was inspired by his beloved wife and her love of chameleons. The company logo was something that they collaborated on and a local artist brought it to life.

Mr. Geisler was driven to expand with experienced, trusted, and credible Investigators. He formed many professional relationships throughout the course of his career that carries into today. Blue Chameleon Investigations is a full-service Investigation Agency that offers a broad variety of experience and the majority of our team is retired law enforcement.
