As co-President & CEO, Sara leads business development and strategy initiatives for Pro-Change Behavior Systems. She has also been instrumental in the implementation of innovative research and development opportunities related to best practices in behavior change. Sara brings to her role over 20 years of experience developing behavior change solutions in a variety of domains, including weight management, smoking cessation, medication adherence, and medical education.

She has been the principal investigator on over $4.7 million in National Institutes of Health grants to examine the effectiveness of Transtheoretical Model-based interventions. She is currently leading new research initiatives to integrate individual- and culture-level interventions to enhance well-being; increase engagement with evidence-based mobile apps that promote behavior change; and develop interventions for pain self-management, sleep, and financial well-being.

Dr. Johnson also serves as the Co-Editor of The Art of Health Promotion. She was named a Top 10 Health Promotion Professional in 2015 by WELCOA.
