Allison Silvestri
 Dr. Allison Silvestri, Principal
I am a San Mateo native and returned to the Bay Area in 2001. I attended Boston College and completed my Bachelor of Arts in English and attained my credential before entering the Master’s program in the field of mild/moderate special needs. Following my time on the East coast, I spent a year volunteering in the small, rural village of San Blas, Costa Rica where I taught English as a foreign language. When I returned to the states, I landed a teaching position in the resource program at San Mateo High School. After a wonderful tenure, I left San Mateo High to pursue my love of travel and teaching abroad. I home-schooled two children in the South Pacific before becoming a scuba dive master in Thailand. Finally, I put my orange back on and taught English and Social Science to students in the Special Day Class program at Woodside High School. In the spring of 2010, I earned another master's degree from Notre Dame de Namur in the field of public administration. After three years as the Assistant Principal of Curriculum and Instruction at Half Moon Bay High School, I was named Principal in July 2012. As of July 1, 2014, I transitioned to a principal position at Acalanes High School in Lafayette. I joined the Grizzly community in San Lorenzo in 2016 and completed my doctorate from California State University, East Bay in Educational Leadership for Social Justice and Equity in June of 2018.  I am excited to join the founding members of TIDE and to collaborate with the team as we open the doors to this new, forward thinking school.

 Alanna Baumert, English Teacher
Alanna received a B.A. in English with a focus on Teaching English Literature from San Francisco State University in 2009. After obtaining her Teaching Credential from Mills College in Oakland, she went on to teach middle school Humanities in Berkeley and has spent the last six years teaching English and History in East Oakland. In 2017, she completed a Master’s in Teaching. Her research focused on effective reading strategy instruction for secondary students. She loves watching students develop confidence in their ability to communicate their ideas. Alanna feels that a child’s community plays an important part in their physical, mental, and emotional wellbeing. This connection to the environment has a direct impact on their ability to feel successful when learning. She believes a love of learning is developed over time, through honing diverse academic and social skills, tracking growth, as well as engaging in metacognitive reflection. Alanna is well known for being prepared for any outdoor adventure whether hiking in the mountains or taking road trips along the Pacific Northwest.
Ms. Cole
Cat Cole, Social Studies Teacher
Cat Cole was born and raised in San Francisco, where she grew to love learning. She adventured to the East Coast for her college years to attend Vassar, where she fell in love with historical research and changed her major from neuroscience to history. Following her passion for education, she completed her master’s in education at Lesley University and earned teaching credentials in social studies and English. From Oakland to Thailand, she has worked in different school settings. She loves to swim and go to Zumba classes for exercise. On the weekend she can be found taking beautiful walks along the ocean in Pacifica, where she now lives. At TIDE Academy, Cat cannot wait to lead historical inquiry that will help students understand who they are, why the world around them looks the way it does, and how the patterns and cycles of history continue to repeat themselves.

Jim Karditzas
Jim Karditzas, Mathematics Teacher
Jim Karditzas started life in Illinois just outside of Chicago and at 10 years of age his family moved to Florida. He was the first in his family to finish college graduating from The United States Military at West Point in 1981 with a Bachelor of Science in Electrical Engineering. After a 10 year career in the US Army as an Armor officer including completing a Master's Degree in East Asian Studies at USC in 1990, he resigned his commission to pursue personal goals. Leveraging his leadership skills and technical expertise he landed in high-tech sales in the Bay Area for 15 years. In the last years of his sales positions he was training non-technical sales professionals to sell high-tech components with both classroom and in-field co-selling appointments. His passion for teaching caused him to re-tool once again to pursue a Master's Degree in Education (Mathematics) to redirect his path of service to a career in public education. He has been teaching and coaching students and teachers in mathematics education for the past 14 years and is delighted to help in the launch of a new school. He brings energy and critical thinking to mathematics by integrating relevant instructional strategies that focus on developing student agency and authority as a mathematician.
