History:
 
We are a family owned and operated California Corporation, started by renowned Private Investigator,  Marvin T. Frost, in 1964. Marvin Frost worked as an investigator for the City of Los Angeles, Department of Workers Compensation, until he was convinced to come to work for a Los Angeles-based law firm connected to celebrated attorney Melvin Belli. He handled many of Attorney Belli’s complex and famous cases, resulting in travel throughout the State of California, United States and Mexico. During this time, he was also doing work on his own. Because he spent much of his time working, he often brought his family with him on many of the cases. When appropriate, he introduced those investigations to his children, providing a rare opportunity for his son, Gregory Frost, at an early age, to learn how to conduct investigations and how to approach people.  Marvin Frost operated the company until his retirement, in 1996, when he turned over operations to Gregory Frost, President, who had been working for the company since High School.
