Brook Madera is a PDA (Pathological Demand Avoidance) advocate, author, and lived-experience consultant based in Oregon, who has built a following of over 22,000 as "No Pressure PDA" and founded a U.S.-based nonprofit supporting the PDA community. She holds a B.A. in Religious Studies and an M.A. in Human Services Counseling, and previously served as lived-experience consultant for PDA North America, where she has also spoken at the 2024 and 2025 annual conferences. Brook co-founded PDA Insiders alongside Sally Cat — a qualified person-centered counselor and fellow #actuallyPDA voice — with the shared mission of explaining PDA with a clarity that can only come from living it. Together they co-authored The Insider's Guide to PDA, widely recognized as the first PDA textbook written by #actuallyPDA individuals. Brook lives with her three PDA children and focuses particularly on helping families navigate PDA burnout, sibling dynamics, and comorbid conditions.
