Very easy to work with. Very professional, thorough, and understand. Definitely worth the time and money. We have used his services for nearly 2 years in a child custody matter. He saved us a lot of time heart ache and grief. He helped us realize that there are crooked people out there that need to be watched. If you need a great and experience private investigator this is the one for you. We would very highly recommend.

I found this detective online and hired their company. The owner being from law enforcement has a good background and was wonderful with respect to taking care of what we needed to succeed in winning our criminal case. Reasonable for the work completed and actually cheapest around.
