“I am so pleased with our county’s Secure Medicine Return law and that we have a great state law now too. Margaret has been at the center of this effort as our policy expert and the tireless organizer of all the supporters.”

David Baker

“Margaret helped Washington stay focused and continue to push for powerful and meaningful drug take-back legislation in Washington State. She helped coordinate efforts across the state among a variety of stakeholders. Her leadership provided the necessary organizational structure to build a broad coalition of stakeholders necessary to pass this legislation. Robust legislation takes years to develop and pass. Her patience, perseverance, and leadership was essential for success.”
