DO NOT HIRE ! Retained Mr Knopf to provide information about my grandson's foster care home. Asked for pictures about living conditions, interaction with foster parents to be able to contest placement in court. Mr. Knopf was given home address, day care provider, lifestyle info, including foster parent's work schedule. Mr. Knopf provided me with 3 pictures of a privacy fence around the address and told me it was the best he could do. He did not even attempt to get pictures of my grandson claiming he could not approach the child. That's what telephoto lenses are for. Any amateur could have done better. Knopf, you ripped me off and I am not amused!
