Evidence-based health and well-being for entire populations.

Janet L. Johnson, Ph.D.

Senior Vice President of Innovation and Implementation


Dr. Johnson leads the development of our software reporting engine, oversees continuous quality improvements to our LifeStyle Management Suite, and manages relationships with some of our key partners. Dr. Johnson facilitates the translation of the science of behavior change into our technology for delivering our programs to both adults and adolescents.

She has worked on a variety of health projects covering a wide scope of health behaviors including smoking cessation, sun exposure, adolescent substance abuse, healthy eating, exercise, and decision making for health care and organ donation. Her research interests include methodology and statistics and use of technology in behavior change interventions.

Winner of the Peter Merenda prize in 2001 for outstanding student work in the area of statistics and research, Dr. Johnson received her Ph.D. in Experimental Psychology from the University of Rhode Island.
