Founder & Executive Director
Callum Rutherford
Callum founded Citizens Against DHMO in 2019 after a viral social-media thread documenting his discovery of the substance's presence in his children's bath water received 4.7 million views in 72 hours. A former senior policy analyst at a major environmental advocacy group, Callum has built the movement from a single Reddit post into a 47-chapter grassroots network. He holds an MA in Public Policy from a school he prefers not to name in advocacy materials.
“We are not anti-DHMO. We are anti-secrecy. Every citizen deserves to know what is in their water, their food, and their children's school cafeteria.”
