The principal of the company has over 30 years of experience in the investigative field.

Inter-State is staffed with an eclectic mix of investigators with varying backgrounds and unique skill sets including law enforcement, military, science, real estate and accounting. We are comprised of male and female investigators, some of whom are fluent in Spanish. All investigators are experienced and receive continuous training.
