“Blackfish was really great to work with.  We had a very painful and complicated child custody case, but they advised us through the process, provided all the evidence we needed, and were there to support us in court.  Thanks to their efforts, our family is whole again."

Tom G.

“I was falsely accused of a serious crime, but Blackfish came in and took the time to do a complete, professional job, and discovered evidence that PROVED I was innocent.  All charges were dropped, which saved me a fortune, and now I can move forward with my life."

Raymond S.

“While it was devastating to learn that my husband was having an affair, Blackfish's investigators were very compassionate about my situation.  They documented his behavior, and put me in the best position to protect my assets.  I am so thankful for their work!”
