Report
My Firm has worked with Bob Hanrahan of RGH Investigations for the last fifteen years and we have never been disappointed. Bob and his team specialize in handling just about anything that an attorney could possibly require both for trials and day to day operations. From interviewing witnesses to getting documents, police reports, medical records, (and anything else), Bob always comes through very quickly. I would highly recommend RGH Investigations and Bob Hanrahan to attorneys for any and all needs.
