Vanguard is my "go to" agency for investigative work on my family law cases. They do a thorough job for a price that my clients can live with. Knowing that Vanguard is made up of former law enforcement officers gives me the confidence to know that if I need them to testify, it won't be their first rodeo. C. MacDonald, Esq.
