Recent reviews from our SATISFIED clients

  • review rating 5  Nothing but praises for Chad at Assurance Investigations. He helped me get back stolen equipment. This equipment was my life line and can not make money without it. He knew exactly what needed to be done and got it DONE! You sir have a customer for life.

    thumb Jeremy Sandler
  • review rating 5  They did what they stated and brought me peace of mind. In a very hectic time for me. They put it in their hands to resolve some issues i had. If you need a private detective this is the choice I would recommend.

    thumb Amy Smith
  • review rating 5  I work for a law firm located out of state, and Assurance Investigations and Process Service were very quick and helpful with process service as I am not familiar with the metropolitan areas in CO. I appreciated that I could upload the service documents and pay online, and the return of service was emailed to me quickly (no mailing payments, having to wait for a quote, or waiting for a return of service to be mailed). Whenever I need to serve in CO, I don't have to think about which process server to use. Very fast, professional, and affordable.

    thumb Liz Hilst
  • review rating 5  Assurance has been our go-to process server for nearly as long as our firm has been representing clients in litigation. Assurance has a keen eye for detail, and we have had a number of legal issues that would not have been resolved in our favor without Assurance's astute affidavits.

    thumb Jordan Thomas
  • review rating 5  Amazing service, needed something served to protect my children and Chad went above and beyond to serve it in the same day. Highly recommend.
