Our firm had trouble getting a defendant served with a court summons in St. Louis; we had used multiple process service companies in the St. Louis area but to no avail. Then we were recommended to A.A.I. Legal Support Service of St. Louis, after they got the job it was served immediately. As far as we are concerned A.A.I. Legal Support Service of St. Louis is the most professional and competent process service & investigations company in Missouri.
