    1st Grade Teacher

    Hello families and visitors! My name is Rizelle Murallon, and I am so excited to continue my work with the High Tech High organization, this year as a first grade teacher! A little bit about myself: I grew up both in the Bay Area and in Sacramento, but always had a love for San Diego's beautiful weather and beaches. School and education have always been my passion, and after helping raise my little brother Liam (who is fourteen years younger than me), I always knew I wanted to work with children and be a part of their development and love for learning.

    When the opportunity came for me to pack up and make San Diego home in 2015, I took it! Transferring to SDSU, I later graduated in 2017, receiving a Bachelors of Arts degree in Liberal Studies with an emphasis in Elementary Education and Literacy. Throughout the 2017-2018 and 2018-2019 school year, I worked as an Academic Coach at HTe, Point Loma, in kindergarten and 1st grade classrooms. I completed my student teaching in a fifth grade and kindergarten classroom at HTeCV, receiving my multiple-subject teaching credential in May 2019. Currently I am working on my Masters in Teaching degree with Point Loma Nazarene University, and I'm looking forward to starting my third year with the HTH organization as a founding HTeM teacher.

    Outside of the classroom, a few of my favorite things to do are: eating really good food (noodles are my favorite!); planning and doodling in my Passion Planner; and I especially love being outdoors, it means I can spend some quality time in the sun with my husband Jimmy and our Olde English Bulldog Blu(berry) and French Bulldog Potato!

    I look forward to spending this year learning and growing with you!

    1st Grade Teacher

    I am so excited to join the first grade team at High Tech Elementary Mesa, because of my wholehearted passion to help young students learn and grow. After graduating from Wellesley College, I joined Teach For America (TFA) in Houston, Texas where I taught kindergarten at a KIPP charter school. After a few years teaching in Houston, I studied at the University of Texas at Austin in order to develop a better understanding of current and challenging education policy issues affecting students across our country. After my masters program, I worked at TFA as a development officer raising funds for teachers for three years. Last year, I returned to the classroom as a kindergarten academic coach at High Tech Elementary North County. In my classroom, it is my priority to build strong, trusting relationships with each one of my students while guiding them to fulfill their full potential. I look forward to this year at High Tech Elementary Mesa!

    2nd Grade Teacher

    I am very excited to be a founding staff member at HTeM as a 2nd grade teacher! I have recently received a multiple subject teaching credential as well as a special education teaching credential through Point Loma Nazarene University. I am currently pursuing my Master’s of Teaching through PLNU, as well. 

    I am originally from Columbia, Missouri and moved to San Diego in 2013 to attend the University of San Diego. There, I earned my Bachelor’s in Business Administration with a minor in Leadership Studies. After graduating, I spent time volunteering at the Monarch School as well as substitute teaching. These experiences grew my passion for teaching and empowering students. 

    Outside of the classroom I enjoy eating and making delicious food, shopping for new plants, and hanging out with my older brother (who moved to San Diego just last year)! 

    I look forward to growing and learning with you this year!

    3rd Grade Teacher

    I am thrilled to be a founding staff member of HTeM as a 2nd grade teacher. I’ve been an educator for 21 years. I graduated from Loyola Marymount University with a B.A. in Psychology, earned multiple subject teaching credential through Cal State San Marcos, and earned a Master’s in Education from Chapman University with an emphasis in reading instruction. This school year I am pursuing my Special Education credential through the HTH Graduate School of Education.

    I started my career in my hometown, San Diego, working in San Diego City Schools as an upper grade teacher and later as a literacy instruction peer coach where I served primarily emergent bilingual and refugee students. Afterwards I worked at an international school in Valencia, Venezuela for two years. It was during my time in Venezuela that I met my future husband, Robert. I made my way back to San Diego with Robert in tow, and luckily found a position working at High Tech High Explorer Elementary as an upper-grade teacher, where I worked for ten years. My family and I moved to Hawaii for the 2017-2018 school year to open up an elementary school at the Asia Pacific International School on North Shore, Oahu. After one enriching year in Hawaii, we made our way back to San Diego. My most recent work was with the HTH GSE’s Center for Research on Equity and Innovation.

    My teaching passions are rooted in pedagogy that is culturally responsive, project-based, and service oriented. I believe that developing students to be socially-emotionally skilled is critical to helping students become their best selves and to make a true difference in the world.  My hope is that all my students experience joy and feel a strong sense of belonging within our classroom community.

    Outside of school you will find me outdoors, practicing yoga, hiking, traveling, learning, being a mama to my 4th-grade son and 1st-grade daughter, and spending time with family and friends.

    STEAM Exploratory Teacher

    Hello students, families, and the community! My name is Tawny De Alva and I am thrilled to be a part of the launch of High Tech Elementary Mesa this year. I will be your child's STEAM exploratory teacher as well as an induction mentor for new teachers. This is very exciting-- all the creative tabs of my mind are open right now! 
    I was born and raised in San Diego, California, where I completed my undergraduate degree at UCSD, majoring in Sociology and minoring in both Teacher Education and Ethnic Studies. I have been teaching since 2005, where I have taught TK-2nd grade, with a long emphasis in Kindergarten. In 2013, I received my Master's of Art in Teaching at SDSU with a concentration in Language Arts Curriculum and Instruction. In my teaching career, I have been honored "Mama Cub of the Year" at King/Chavez Primary Academy in Barrio Logan, as well as served on the founding team of Hawking STEAM Charter Schools in Chula Vista. I hope you feel my passion in building kindness and empathy, transforming education, as well as connecting with your child, as we explore projects and STEAM together! 
    I have three children myself, and I know how much time, energy, and commitment it takes to fully prepare them for the world. Hats off to you, parents! In all honesty, a beautiful moment to me is enjoying a cup of coffee, fresh air, and laughter. A clean house and occasional shopping doesn't hurt either, right?  
    I am so privileged to work alongside this amazing team of educators, and I look forward to crossing paths with you on campus. Go Mesa!!

    Angel Mendoza
    Academic Coach

    Hello! My name is Angel Mendoza and I am extremely honored to be starting my new journey at High Tech High Mesa as an Academic Coach. It is truly amazing finding a community that is so passionate and determined to facilitate such a unique and empowering environment for all students. I am currently pursuing my M. Ed in Special Education with Multi-subject Credential at the University of San Diego. I graduated with a Bachelor’s degree in Sociology at National University. I am proud to say that I grew up experiencing the rich culture of Barrio Logan, where community, unity, and family, were constantly being celebrated.

    My biggest passion has to be living an active and healthy lifestyle. I grew playing soccer, football, and basketball with the neighborhood kids. I learned how to play the drum set, timbales, and congas to play at cultural events with my friends and family. When I got older I learned how to dance many Latin dance styles from Salsa, Merengue, Batchata, Cha Cha, Ballroom, and more. As I got older, I got into boxing, kickboxing, and rock climbing. However, Music was my main passion.

    It has always been a passion of mine to teach, guide, motivate, and inspire children. Becoming an educator helps me practice that every day. My goal is to look into the eyes of each student and reinforce the endless potential they hold within themselves. To show that education is a powerful resource that can truly empower them in the future. I aim to inspire their inner determination, tenacity, and innovation beyond their own expectations and break through any limitation they have set before themselves. As a teacher, I intend to model respect, compassion, and positive self-esteem every day with interpersonal connections and empathetic conversations. My hopes are to lay a foundation for a community based atmosphere. By creating an environment that facilitates personal growth, productivity, self-efficacy, and students can and will be equipped to be positive role models now and in the future.

    It is a passion of mine to create an inclusive educational system that is conducive to all students. To accommodate the diversity of needs, recognize the pace of development, and respond with flexible ranges of responses and recommendations. I want to identify barriers and aim to reduce or eliminate them. It is essential that all students invest in themselves, take pride in their culture, and find their own creative way to utilize education to make this world a better place.

    Bethany is the HTeM team as an Education Specialist supporting the K-2nd teams in her 8th year of teaching. Bethany is excited to continue to develop the culture of inclusion by providing specific structure and supports for learners to thrive in her 5th year within the High Tech High community.

    Bethany is one part, local San Diegan, and one part San Franciscan. Prior to joining the HTeM team, Bethany worked in the San Francisco Bay Area as a special education teacher of the upper elementary grades. She received her Masters in Special Education from Loyola Marymount University in Los Angeles, and her Bachelors of Science in International Studies from Point Loma Nazarene University. Through her formal education, Bethany has explored the characteristics of a successful school and community garden in San Diego, and San Francisco. She developed the conviction that experiential learning (and sometimes rolling up our sleeves and getting dirty) acts as the best medium for cultivating genuine engagement and intellectual growth when she established a school garden at an elementary school. She is passionate in supporting teachers with the implementation of Universal Design for Learning and is relentless about developing best practices for her field. She is a major proponent for the Zones of Regulation and Social Thinking programs. Bethany believes that fostering student self-advocacy is essential for transformative educational growth.

    Outside of HTeM, Bethany is finding the perfect cup of coffee, practicing yoga, playing a card game, training for the Rock and Roll Half Marathon, and planning a wedding.

    More than anything else, I feel my true calling is in the classroom with teachers and students. And it is this love for classroom teaching and learning that I hope to bring to my leadership role at HTe Mesa. Prior to joining the High Tech High community, I taught primary grades in New York City public schools for seven years and served as a literacy specialist for another ten years at the Columbia Teachers College Reading and Writing Project. In that role, I had the privilege of supporting teachers, coaches and administrators across the United States, and in international cities such as Paris and Shanghai. Wonderful as that work was, I missed being in a school community on a day to day basis––a yearning that led me to forge a role as an academic director and instructional coach at the Harlem Village Academy in Harlem, New York. This was a particularly thrilling role that allowed me to combine these administrative duties with daily teaching in a kindergarten classroom.

    I’m thrilled to be joining the Clairemont neighborhood and the greater High Tech High community alongside my husband and four children. We all look forward to making San Diego our new home.

    School Psychologist

    I have been working within the field of Education since 2009 in various roles: Teacher, Creative Arts Therapist, Researcher, and School Psychologist. I am a native New Yorker, who moved to Boston to pursue degrees in Child Development and School Psychology from Tufts University. Prior to working in the field of School Psychology, I was heavily immersed in the field of research for various institutes including Tufts University, MIT, and Tufts Floating Hospital for Children. My research projects included investigating resilience factors in students who participated in music programs, researching the benefits of neurofeedback programs in schools for children who were diagnosed with ADHD, and looking at brain development to identify early indicators of Dyslexia.
    I am passionate about Social Emotional Learning, Social Justice, collaborating with parents and advocating for all of our students needs.
    I recently presented at the National Association for School Psychology Conference (2019) on creating effective mental health systems within schools, and received the California School Psychology Award (2019) to implement Social-Emotional Curriculum within Schools.
    Outside of work I enjoy hiking, baking, reading, traveling and adventuring with my dog.
