She and her husband moved to Sarasota from the Washington, D.C., area in 2005.

We knew this was home.” Their daughters, Camille and Evangeline, were born in Sarasota in 2008 and 2013 respectively. Fluent in English and Spanish, Dr. Cotera enjoys traveling to new places, exercising, movies, music and spending time with her family.
