Callan Detective Agency, Inc. is a full service investigation company whose main objective is helping people seek the truth. We are fully prepared to assist both the individual and companies, large or small, who seek our assistance. Our agency has the experience, technique, and strategy needed for all successful investigations. Regardless of size, all our investigations are executed with discretion, professionalism, and accuracy.

Although many private investigation firms have a law enforcement background, it may not be common that they have experience as a criminal detective. Out of the firms that have a detective background, how many have the experience conducting the type of investigation you require? Our agency was founded by a retired police detective that not only led complex, high intensity investigations, but supervised a criminal detective division. As a result, our agency understands the technicalities, risk, and liability involved in any type of investigation. We execute every case with professionalism, accuracy, and detail, no matter the size. Please refer to our List of Services for areas of expertise.
