    Dr. O At Casa, we say “everyone has a place at the Big House”. At the heart of this motto is the belief that we are all unique, beautiful humans, who bring an incredible diversity and energy to everything we do, and to our incredible school, Casa Grande.   At Casa, we also say “it’s a Great Day to be a Gaucho” – a motto that always brings a smile to our staff and students, a rallying cry for perseverance and achievement, and a reminder of how important our time is together.  As Principal, I commit to making sure everyone believes they have a place at the Big House, and to making sure each and every day truly IS a great day to be a Gaucho.  I believe education flourishes with strong relationships.  Every day, I look forward to helping shape the direction and culture of our school – drawing from daily visits to classrooms, methodical research and data analysis, interactions with students and staff, and constant engagement with parents and the community to inform all decisions.  

    The culture and history of Casa is extremely inspiring to me and I am committed to fostering what I sincerely believe to be a truly phenomenal high school.  I look forward to every opportunity to serve an innovative, diverse, and rigorous comprehensive program that features a long and inspiring tradition of excellence.  My inspiration is rooted in a steadfast commitment to student voice, equity, and an accountability rooted in our school-wide mission and vision:  Upon graduation, all students at Casa Grande High School will be Broadly Literate, Highly Employable, Civically Engaged, and have a Personal Vision for their future.  This is the vision of Casa, and this is what I am committed to.

    Biography:  Raised in northeastern Oregon, I began my college career as a music major.  I concluded my bachelor's degree journey at the California Institute of the Arts in Los Angeles, where I finished a Bachelor of Fine Arts in Jazz Trombone with a minor in Composition.  For over 10 years I worked as a professional musician, composer, arranger, and producer throughout southern California.  During this time, I had the honor of performing and/or recording with many great artists.  I also won awards for original compositions, scored films, and produced many recordings.  Music will always be a strong and defining force in my life.  Along the way, I discovered that education is my life's work - informed significantly from my many years building community through music.  In 2010, I completed an MA in Education at Loyola Marymount University and in 2015, I completed a Doctor of Education (Ed.D.) degree from the University of Southern California, publishing a case study dissertation looking at how arts integration programming fosters English language development.  Dr. O lives in Petaluma with his wonderful wife, son Theodore, and their fluffy dog Owen.  He is often found hiking Mt. Tamalpais and enjoying the wonders of the north bay.

    Assistant Principal Lee I am honored to serve as an assistant principal at Casa Grande High School. I view my role as an administrator as a great responsibility and I strive to positively impact students, staff, families, and the community. I believe that students achieve more when they are surrounded by compassionate adults who can challenge them and support them as they learn and grow. To this end, I am looking forward to partnering with the other administrators and staff to give our Gauchos a high-quality, engaging, and rigorous education that will prepare them for success during and after high school.

    Biography: I earned my Bachelor's Degree in English Literature with an emphasis on Secondary Education at Sonoma State University. I also completed my Single Subject Teaching Credential in English at SSU. I later went on to complete a Masters's Degree in Educational Leadership and an Administrative Services Credential at San Francisco State University. I have served as a high school classroom teacher and administrator in Petaluma and Novato since 2011. No matter my role within the education system, I always return to my core values, including the belief that education is the great equalizer and an instrument to change the world. I go forward with this belief in the hopes of making a positive impact towards equity and excellence in our school so that our students are empowered to make their own positive and lasting impact on our world.

    I enjoy reading, traveling, and spending time with my family. I am excited to be serving the Petaluma community and look forward to working with the staff, students, and families of Casa Grande High School.

    Luis GarzaI look forward to being a member of the Casa Grande Gaucho family. As Assistant Principal, I will strive to ensure that all students are college and career-ready when they graduate. Additionally, I will encourage each student to cultivate a love of learning that will inspire them to grow personally and professionally after high school. By providing meaningful learning experiences for our students during these formative years, we can challenge them to think and act in ways that make the world a better place.  My work will be to help learners look at their place in the world in order to identify how they can be of service to others.

    Biography: I was born and raised in Bakersfield, California where I attended Garces High School and Bakersfield College. After two years in community college, I was the first in my family to attain an Associate's degree in Liberal Arts. In 1998, I transferred to San Francisco State University to study theater and education. I graduated with a bachelor's degree in Drama in 2000, and I obtained a teacher's credential in English a year later. 

    I wanted to explore the world and connect with my roots, so, in 2002, I moved to Xalapa, Veracruz, in Mexico. I lived there for a year and had an amazing experience. I explored the Americas and met my lovely wife. She emigrated with me upon my return, and we relocated back to the Bay Area.

    My first position as an educator was teaching English at Oakland Military Institute, a public charter school. I was placed as an English Language Development teacher. Because I wanted to learn more about serving English learners, I returned to San Francisco State University and received a master's degree in Teaching English to Speakers of Other Languages. Additionally, I became a national board-certified teacher of students studying English as a new language in 2015. 

    Recently, I finished my master’s in Educational Leadership and obtained my credential in administration. I decided to jump at the chance to come to Casa Grande as an Assistant Principal. The community here has been very welcoming, and I’m excited to start our future together.

    Erika Noone at her desk smilingI have been a Sonoma County resident for 35 years. I grew up in Sebastopol, and  I graduated from Analy High School. I attended the SRJC and Sonoma State, where I graduated with a Bachelors in Liberal Studies through the Hutchins Program. I then went on to earn my Multiple Subject Teaching Credential, also through Sonoma State. I started teaching in 2006 in Rincon Valley. I decided to pursue my Administrative Credential and Masters Degree in 2011 through the University of Phoenix. I wanted to complete my Administrative Credential before I had children. I finished my program in February and six months later, my son was born and two years later, my daughter was born. Now that my children are both in school, I felt it was time to start my administrative career. 

    In my free time, I love being with my husband and kids. I like to play games and go on walks. I enjoy music and singing karaoke when I can. I also love the water. My family has a boat that we take out to Lake Sonoma whenever the weather is nice enough. Right now, my family is in the midst of building a home in one of the communities affected by the Tubbs fire. We love to entertain and hope to create a home that is welcoming and warm.

    Please don't hesitate to contact us if you have any questions, concerns, or ideas about how we can improve our school.
