Author
Zimmer Biomet Employee

Raven S.D. Lopez hails from the Midwest and received her bachelor’s degree from Indiana University. A former social worker, her cases involved everything from substance abuse to domestic violence to human trafficking.

It was through this work that Raven became increasingly interested in social determinants of health and public health policy.

Raven and her husband live in Indiana, catering to the whims of a bossy cat and ever-anxious Labrador. When she isn’t working you can find her hunting for the next great book to add to her library (she owns over 1,100 books!) or convincing her husband to start another home renovation project.
