Prompt reply to leaving a voice message and very professional when handling our case. Searching for a Seattle investigator was nerve-racking as there are many investigators to choose from, but speaking with Washington State Investigators made us feel at ease and they were empathetic to our needs. They provided exceptional customer service and professionalism even though our case took a few turns during the investigation. We would highly recommend Washington State Investigators to anyone who wants their case handled professionally. Thank you with much appreciation.
