Chrystine Zacherau is an advocate at heart who combines skills in opinion research, a calling as a nurse, and experience as a strategist. She built a career on listening to others—through formal research and other stakeholder engagement—to raise their voices and offer evidence that makes an impact on health. Chrystine is trusted as counsel to some of the world’s largest biopharmaceutical companies, health systems, provider and patient organizations and non-profits—and she is most proud of the work she does to recognize the integral role of nurses and the ability of patients to be active decision-makers in their care. Chrystine was a founding member of APCO Insight where she built a health-focused research capability. Chrystine continues her nursing practice through volunteerism in Guatemala with Mayanza, an organization focused on transforming communities by improving the health of school-aged children and their mothers. Also, she supports vaccine clinics run by her local public health department. Chrystine holds a BA in Political Science from Marist College, a BS in Nursing from George Mason University, a MA in Survey Research Methodology from the University of Connecticut, and a Public Health Certificate from Rutgers University.
