Kindergarten Teacher
I was born and raised in San Diego, more specifically in the Southeast area of San Diego. I went to San Diego State University where I got my Bachelors degree in Liberal Studies with an emphasis in Elementary Education.

My parents are both from Guadalajara. My two siblings and I grew up speaking Spanish and embracing our culture by connecting with family and keeping our traditions alive.

This will be my 4th year at HTeX and my 2nd year teaching kindergarten. I’m a BIG family person so in my spare time I love spending time at home with my husband and our 1 year old son Jorge-Carlos. Pre-quarantine, we enjoy getting together with my parents and my in-laws (who only live minutes away from us) for weekly family dinners. I also enjoy getting outside and being active. My husband and I host Softball Sundays with our friends and family every month. When the winter season comes, we make our annual trip to Big Bear and spend our day snowboarding. Lastly, I am a huge Disney fan! It’s a love that my husband and son quickly (and involuntarily) grew to love as well :)

Kindergarten Teacher
I was born and raised in North Carolina and am from a big family of five kids! I went to college at the University of North Carolina at Chapel Hill, where I studied Spanish, psychology, and neuroscience. Before becoming a teacher, I also worked as a summer camp director, nanny, tutor and researcher.  All of these jobs helped me realize my passion for connecting with families and helping students learn and grow. I was so excited about project-based learning and the wonder of early childhood that I moved all the way to San Diego to become a teacher. 

This is my fourth year working in the classroom, and my second year teaching kindergarten. Last year, I earned my Masters of Education in Teaching & Learning through High Tech High's Graduate School of Education. For more information about me and my beliefs about teaching children, please check out my digital portfolio.

When I am not at school, I enjoy all things involving the great outdoors! I am a gardener, hiker, swimmer, and avid frolicker. Being in nature makes me feel energized and happy. I also love weightlifting, laughing, solving tricky math problems, and snuggling with my dog (Murphey).

Dana GaertnerDP
1st Grade Teacher

Hello! My name is Ms. Dana, and I’m excited for another fun year of teaching and learning together. I earned my Bachelor's degree in Human Development and Family Studies from the University of Wisconsin Stout. From there, I gradually made my way west, teaching and learning in large urban school districts in both Minnesota and Colorado.

I began my career in education as a Kindergarten and First Grade teacher under The New Teacher Project, and then worked on a team of instructional superintendents as a School Improvement Partner for several years in Denver Public Schools. While doing this work, I also attended graduate school for Educational Leadership and Policy Studies, focused on turnaround schools, at the University of Denver.

During that time, I came to visit the HTH system with my leadership cohort, and was immediately drawn to the joy, engagement, and rigor of Project-Based-Learning. After graduating, I moved to San Diego to work as a 3rd and 4th grade mentor teacher. It was there that I developed a love of engineering, and creating interdisciplinary projects for my students.

I currently live on a micro farm in Escondido, where we grow food for San Diego Co-Harvest, an organization that supports people who struggle with food insecurity. When I’m not working in the garden or taking care of our chickens, I love to design, create, and cook! I also enjoy snowboarding, traveling, and spending time at the beach.

3rd Grade Teacher
Hello all. My name is Anna. I was born in San Francisco with my twin sister, but I spend my first five years in Guangzhou, China. At age 6, I moved back to California where we were raised in Los Angeles. I  decided to move to San Diego to earn my B.A in Sociology at University of California, San Diego. After receiving my B.A  I brought my passion for teaching to the rural parts of South Korea to serve English language learners from K-6th grade. When I  finished teaching in South Korea, I decided to go back to UCSD to earn my Multiple Subjects Credential and Masters in Education Studies. During that time, I learned a great deal about bilingual education, so once I finished my Masters program I went abroad and taught 1st and 3rd grade in an International School in China. There I continued to work with English language learners and learn more about the Chinese language and culture. Although I love to travel, I am California girl at heart. After teaching in China, I moved to Berkeley, California, where I taught Kindergarten for the last two years.

In my spare time I like to spend time with my sisters and drink boba milk tea. I also likes outdoor activities such as hiking, running, and cycling. I  identify herself as a lifelong learner and enjoys taking professional development and binge on TED Talk videos. ​
