TIDE Academy - Simone Rick-Kennel

Simone Kennel, Principal

As a lifelong educator at heart, I am excited to serve as the Principal at TIDE Academy. The start of the 2021 school marked the beginning of my 29th year in education and my 20th year with the Sequoia Union High School District. Menlo-Atherton High School was my home for the last 19 years. I look forward to serving our collective community at TIDE, which is a very special, unique gem in the Sequoia Union High School District and one I am thrilled to be part of.
A little bit about me...
I immigrated to the United States when I was 9 years old from Johannesburg, South Africa. with my parents, brother and sister. My father was born in Zimbabwe (Rhodesia at the time) and my mother was born in Johannesburg, where they met.  I have had the parent experience of having a high schooler as my son is now in his Junior year of college.
I earned my Bachelor of Arts degree at U.C. Berkeley in English and continued to pursue graduate education, including a Master of Arts degree in Special Education and several teaching credentials. My career began as a middle school Special Education and high school English teacher. I also taught graduate-level courses at San Francisco State University. Since 2007, I’ve been in administrative roles including Dean of Students and Administrative Vice Principal, and for the last six years served as Principal. In 2020, I was selected as the Association of School Administrators (ACSA) Region 5 Principal of the Year.
I can wholeheartedly say it’s been a fantastic journey at TIDE  and I look forward to continuing to nurture our small public high school offering a STEAM-focused program via career technical education pathways and dual enrollment with Foothill College.

Tina Smith, Vice Principal

As a science teacher for 18 years, Ms.Tina Smith designed and implemented a Biotechnology program at Carlmont High School that included three courses of study.  Ms. Smith also was part of the team that founded the Biotechnology Institute (BTI), a cross-curricular, small-learning community where students take science-themed English and social studies classes as well as a series of courses in biotechnology. She has taken several classes in Costa Rica to help researchers collect data and protect Leatherback Sea Turtles as well as to aid in reforestation projects.  Ms. Smith discovered that she enjoys creating change in education. She wants relevancy for students, a way for students to link what they are learning with what they will do as a career. She wants every student to have access to entering their desired industry, regardless of having or lacking family connections. 

In 2018, Ms. Smith decided to leave the classroom and become the Career Technical Education (CTE) Coordinator for the San Mateo County Office of Education.  As a result, she was able to outreach to more districts, schools, and students across the county supporting the development of similar programs. 

Tina is now the Vice Principal at TIDE Academy. She is located at the first office on the second story of TIDE. While her door is always open, it’s best to make an appointment with Ms. Chavez to ensure Ms. Smith is not otherwise engaged.

John Allen, Spanish Teacher

¡Hola! Me llamo Señor Allen y estoy súper emocionado de trabajar aquí en la escuela de Tide Academy.
Mi historia: I have been a Spanish teacher for the past 16 years, and I have taught at both the secondary and university levels. This will be my first-year teaching at a STEAM school and I’m very excited! I have spent the majority of my career teaching high school Spanish at all levels (1-5AP). I am a reader for CollegeBoard, and every summer I grade the nation’s AP Spanish Language and Culture exam.
I received a BA in Spanish from WKU after which I pursued a Master’s degree in Bilingual Education with an emphasis in Spanish. Next, I taught undergraduate courses at Ohio University while pursuing another Master’s degree in Hispanic Literature/ Applied Linguistics. My study abroad experiences include studying abroad on three different occasions in my undergraduate study both in Mexico and in Spain. I was a student for about a year at two different Mexican universities, and one university in Spain.
Most recently, I have been a teacher at Los Gatos High School teaching Spanish 3 and Spanish 5AP. I have had a 100% passing rate for the students in my class taking the AP exam. I was awarded “Educator of the Year” for the school year 2019-2020. Outside of teaching, I started a Quiz Bowl team at Los Gatos, and we traveled and competed all throughout California. I was also the Speech and Debate coach at several schools where I have previously worked. I competed in Speech and Debate from middle school through the collegiate level and was on the National and International Championship team in college.
Mi filosofía: The best way to learn a language is to be immersed in it, so my classroom is, for the most part, an English-free space. Students are encouraged to take academic and personal risks, pushing themselves to listen, speak, read, and write in Spanish on a daily basis. Though taking academic and personal risks can be intimidating, those who give themselves permission to make and learn from mistakes will experience tremendous growth as hispanohablantes.
Learning a second language also requires significant self-direction, so students will be supported in developing strong executive functioning skills. From adhering to a variety of schedules to evaluating the effectiveness memorization strategies, students will build their executive functioning alongside their Spanish.

TIDE Academy - Jeff Weathers

Jeff Weathers, ENGLISH

I grew up in Nashville, Tennessee, the youngest of five kids, three of us being educators! I have lived in the Bay Area since '93 but was fortunate to spend a year and a half on Catalina Island working at a camp, and then snorkeling and hiking in the afternoons. I'm a musician and songwriter. I play guitar and piano and have over 60 songs that I'm proud of.
Currently, I am working towards my Masters in English and American Literature, excited to write my thesis in a year about one of my favorite books among many, The Catcher in the Rye! I love analyzing literature and movies, having taught both for over 23 years, with Brazil, Cool Hand Luke, and Harold and Maude being among my favorites. I'm naturally drawn towards collaborations and innovations as an educator, and thrilled to be joining TIDE Academy, being ready to change and grow through new challenges!
As an educator, my teachings are guided by the following sayings: "We see things not as they are but as we are" (attributed to several people - Anaïs Nin, Immanuel Kant, and others) and "One does not see anything until one sees its beauty" by Oscar Wilde. The first one makes me aware of my own perceptions. The second one is an inspiration to keep an open perspective and to look for the best in all people and situations. I'm still practicing!
