Daniel Hauff serves as Mercy For Animals’ Director of Investigations. Daniel earned his Bachelor in International Studies with a concentration in Human Rights and Social Justice from DePaul University. It was this passion for justice and compassion that eventually led Daniel toward advocacy efforts on behalf of abused and neglected animals.

Through his work with various local, national, and international animal protection organizations, Daniel has drafted a plethora of animal cruelty complaints on a broad range of issues, engaging law enforcement at the local, state, and federal levels.

Daniel works closely with attorneys, veterinarians and animal welfare experts to compile farmed animal cruelty cases, which have pressed for cruelty prosecutions, strengthened animal protection laws, and encouraged corporate policy changes.

MFA's undercover investigations department has gained national recognition for its extensive work to document and publicize the institutionalized mistreatment of factory-farmed animals. Investigations by Mercy For Animals have led to raids on factory farms, rescue of abused and neglected animals, passage of landmark legislation, corporate policy changes, and opening the hearts and minds of millions of consumers to the power of their food choices.
