Mariana hails from Mexico City, but now lives in Guadalajara. She’s been a preschool teacher for 13 years and loves to volunteer. She started in 2011 with Operation Smile in Chiapas, where she was surrounded by great people who – like her – were just there to help someone in need. After her first stint with Operation Smile – seeing the little ones smile and being so grateful – she realized how lucky she is. Now, she always seeks to share herself and her time with others. To Mariana, the most satisfactory experience anyone can have is helping and giving.
