“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.”
