Let’s welcome our new leader for the 2026-2027 school year! 🌟
Congratulations to our returning Maria Baro on her appointment as principal to Arroyo Elementary School!
Maria Baro
Principal
Arroyo Elementary School
If Maria Baro’s name sounds familiar, it is because she returns to Simi Valley Schools after an almost 10-year hiatus. She started her teaching career at Atherwood Elementary School, followed by Garden Grove and Crestview elementary schools. She comes to us having served as a principal at Oxnard School District.
Ms. Baro received her Bachelor’s degree in Liberal Studies from California State University-Northridge, and her Master’s degree in Educational Leadership from the University of California Los Angeles. She said she went into education because she is a product of great educators.
“I know the power of a great teacher and a supportive school,” she said. “That experience shaped my purpose—to create schools where all students have access, opportunity, and the belief that they can succeed.”
Growing up, Ms. Baro was an English language learner who attended Title 1 schools, and that makes her work in education “deeply personal” for her.
“My hope is to create a school where our students see their language, their culture and their experiences as strengths, where bilingualism is celebrated and every child knows they belong and can succeed at the highest levels,” she said. “I want our students to leave not only academically prepared, but confident in who they are, proud of where they come from and equipped with opportunities that open doors for their future. That means maintaining high expectations, providing strong support and building meaningful partnerships with families.”
She will take the reins from Principal Aldo Calcagno, who retires this year after helping to found the District’s first Dual Language program at Arroyo. When she is not working, Ms. Baro enjoys reading, hiking and spending time with her loved ones.
