It is my honor and privilege to serve the students, staff, and families of the MIT learning community. I have held various roles in public education at the site and district levels. My educational career started as a high school English teacher. I also taught mathematics at both the middle and high school levels. I earned my administrative credential while serving as a curriculum and instructional coach and quickly transitioned into administration. After taking time off to be a mother, I returned as a classroom teacher. Before coming to GTA, I taught mathematics at a Marin County middle school for five years. I’ve had the opportunity to learn and work with different communities across the state of California. It has strengthened my resolve to serve a community through the lens of its people.
This is my 6th year as an administrator at GTA. I am circling back to serving both the middle and high schools. As the Director of Schools, my time is split between Mare Island Technology Academy (grades 6 - 8) and MIT Academy (grades 9-12). When I came to Griffin Technology Academies five years ago, it took me a bit of time to sort out the school names. The middle school was established in 1999. Its name is in long form with all four words spelled out. Even though it is confusing, I can appreciate how the high school took on a short and abbreviated form of the name to create a sense of belonging and ONE community. Of course, this is my interpretation. The founders of our charter schools are active members of the Vallejo community as well as within the GTA organization. I encourage all of us to ask questions and to learn more about our history.
In the spirit of “We Are One,” I am excited that we will all show up and take our seats at the table to design and build a 6-12 learning experience that fosters curiosity and a passion to pursue excellence. Our lived experiences shape our views of the past, our actions in the present, and our hopes for the future. Each of us made a conscientious and informed choice to be part of the MIT family. Voice and choice distinguish a public charter school from other public schools. You have researched our schools and are committed to our code of conduct:
- SAFETY: Practice patience and kindness. Do not hurt and harm.
- OWNERSHIP: Take responsibility for your actions. Be intentional and purposeful with your time.
- ACHIEVEMENT: Be persistent. Take initiative and have follow-through.
- RESPECT: Treat others as you would want to be treated. Walk in their shoes.
I frequently amplify the mantra, “You chose to be at MIT. This choice comes with a commitment to follow school policies and expectations.” We love that our students and families have chosen a school that focuses intensely on not only preparing students to be college-ready, but also giving students a college experience. We believe our students can and will earn. We kindly ask parents and caregivers to engage with their students and with us more than ever.
It was many years ago when I wandered around Merced Community College looking for a drinking fountain and happened upon a flyer and realized that I could sign up for college classes as a high school student. I managed to navigate through the college enrollment process without family support since my parents did not speak English. I started taking night and summer classes. I am thankful to the strangers who went above and beyond to help me out. Looking back in hindsight, I am amazed and awed that no one closed the door on me. Anyone of them could have just told that immigrant, refugee, and unaccompanied girl, “no,” but they did not. It is this level of humanity that drives me to give my best and to rally our team to give their best to each and every student. I invite you to learn and grow with us in supporting our students in and through college so that success is not by chance but by design.

It is a true privilege to serve as the Site Director of MIT High School. Education has been a cornerstone of my life’s journey, and I am deeply committed to fostering a school culture where every student is seen, valued, and empowered to reach their full potential.
My educational foundation includes a Master’s degree in Curriculum and Learning, which has equipped me with a deep understanding of instructional design, student engagement, and academic equity. This school year marks my fourth year as an administrator within the district. I’ve had the honor of serving in multiple leadership roles, including Director of Comprehensive School Improvement and Learning, Site Director, and Assistant Director. These experiences have given me a well-rounded perspective on how to support students, educators, and families across a variety of learning environments.
Growing up in a family of educators, I learned early the value of patience, encouragement, and holding high expectations. One of the most impactful influences in my life was having my mother as my third-grade teacher. That experience helped shape my belief in individualized learning and the importance of meeting students where they are, while supporting them in achieving new heights.
My leadership philosophy is rooted in the belief that every student has unique gifts. It is our collective responsibility as educators to help uncover and develop those talents. At MIT High School, I am dedicated to building a safe, inclusive, and academically challenging environment—one that equips students with both the knowledge and life skills they need to thrive in college, career, and beyond.
Outside of school, I enjoy spending quality time with my family, and engaging in creative pursuits that keep me balanced and inspired. My wife and I love discovering new places with our two Yorkies, and I remain actively involved in my church community. These passions keep me grounded and remind me of the value of creativity, balance, and connection.
I look forward to building strong, collaborative relationships with our students, families, staff, and community partners. My door is always open, and I welcome your ideas, input, and partnership as we work together to make this school year a meaningful and successful one for all.
