Silveira Elementary School, Miller Creek Middle School, and Terra Linda High School. She earned a Bachelor of Science in Biology Education from the University of Maryland and a Master's degree in English as a Second Language Teaching Methods from City University.

Sara loves gardening, hiking, walking her dog, caring for her chickens, getting a cup of coffee with a friend, and reading when she gets a chance.
