I have over 40 years of Law Enforcement and Military experience. I have served as a law enforcement officer/detective, and chief of police. I am a bonded, insured and licensed private investigator in Central Minnesota, licensed through the State of Minnesota Board of Private Detectives (#986). These years of experience, coupled with my integrity and professional persistence, deliver the results you want and deserve.
