I am the Principal of Sylvia Mendez Elementary School and am greatly honored to have the opportunity to lead the school where I began my teaching career 20 years ago. I am greatly honored to return as an educator, but more importantly as a partner, leader, and parent for this school! I came to Sylvia Mendez in the 2023-24 school year with over 13 years as an administrator of our Early Childhood Education program (three preschools - Franklin, Hopkins, and King CDC) in our district and seven years of teaching experience at Sylvia Mendez, formally known as LeConte. At Sylvia Mendez, I taught first grade for five years, third grade one year, and a combo class for third and fourth grade another year.

On a personal note, I was born and raised in Berkeley. I began as a student at Franklin Preschool in the bilingual program. I then went to Thousand Oaks where I attended the Bilingual Program there as well, and finally graduated from Berkeley High. Thanks to my early years in bilingual education I was able to take AP Spanish classes which also helped me in my higher education. In addition to my bilingual education and upbringing, my husband and I want to also provide this experience to our three children, our eldest son who came to Sylvia Mendez and is now at Longfellow and our twins who are following his footsteps and are here in second grade. We truly feel blessed to have this community be part of our family and continue to grow together for all of our children and community!

Ely Amador (Room 7)

Hi, my name is Ely Amador and I have been a TWI teacher in Berkeley since 1999. I received my bachelor’s degree in Developmental Psychology from UC Santa Cruz and my Masters in Education from Mills College. I was born and raised in San Francisco. My parents are Nicaraguan and I grew up bilingually. My experiences in bilingual education sparked a passion in me for educating students to be bilingual, bicultural, and biliterate. I believe it is important to create a fun and safe classroom environment which fosters creativity, trust, self-confidence, and acceptance of individual differences. In my spare time, I enjoy being outdoors in nature, traveling, and spending time with family and friends.

Lourdes Rivas (Room 11)

My name is Lourdes. Students call me Maestre Lourdes. My pronouns are they/them. This is my 11th year teaching Kindergarten at Sylvia Mendez. I am dedicated to creating a safe and joyful classroom environment for all students to learn and thrive. I am passionate about Abolitionist Teaching pedagogy, stress relief running, staying caffeinated, training and co-regulating with my dog Monster. As a teacher, I strive to be the adult in kids’ lives that I wish I had as a kid: honest, patient, unapologetically pro-queer, and socio emotionally in tune to my students. Aside from being a teacher, I am also an author (They Call Me Mix), amateur photographer, newbie climber, and aspiring voice over actor.

Denisse Perez Estrada (Room 13)

Hi! My name is Denisse. Students call me Maestra Denisse or Denisse. My pronouns are she/her.  I love teaching Kindergarten. I firmly believe that everything you need to know you learn in Kindergarten. I am very fortunate to get to spend the day with 5 year olds who love fully and openly. I taught Kindergarten in San Francisco for 6 years and started teaching at Sylvia Mendez in 2021. Every morning I look forward to my first sip of coffee and really enjoy the coffee jitters. When I’m not working, I love reading and traveling with my wife and our four legged son, Remy.

I love our bilingual school community and I am proud of the willingness and passion of our staff to make our Spanish TWI Program better every year. I am a proud mom of a student entering Middle School!  I am passionate about teaching, learning, music, dancing, family, building relationships and community.

I grew up during the dictatorship and from a very young age believed in the importance of human rights, social and environmental justice, and the importance of being allies. I have worked in the field of human rights- including indigenous, LGBTQ, domestic violence and immigrant rights. I began teaching when I was 19, in public education for over 2 decades, and at Sylvia Mendez since 2014. I feel very lucky to be a teacher. I have always been a bookworm, love spending time with my family, plants, being in nature, and laughing. I love to laugh with my students.

I am looking forward to an amazing year!

Greg Martin (Room 5)

Hello. My name is Greg Martin and I have been teaching for a really long time! The fact that I am still teaching after well over 30 years is a testament to how much I love it. I am thrilled to be starting a new year as part of the Sylvia Méndez staff. Our shared goal of developing bilingual students with deep multicultural understandings and sensitivities is so essential during these complicated times. I also feel lucky to have the opportunity to teach, learn and laugh alongside my students during the year. I am also so excited to be job-sharing with Maestra Lupercio. I think we will make a great team to support our students’ growth. 

When I'm not teaching, I enjoy going on new adventures with my wife both locally and abroad.  Both of my beloved daughters are now graduated from college and living their “adult lives” in San Diego. I look forward to the new adventures this year will bring.

I am a proud daughter of immigrant farm workers. I was born in Guadalajara, Mexico, but I was brought here as a little girl. School was not always easy because I was learning English and my teachers did not speak Spanish. In college, I had to re-learn Spanish when I realized I was no longer strong in my language.   

As a child, I collected postage stamps from all over the world. I would dream of one day traveling to all of those countries. My dream came true when I got the opportunity to study abroad in college.

I currently reside in Oakland with my three beautiful children (Jason, Quetzali and Itzel) all of whom attended or have attended Sylvia Mendez. I love teaching at Sylvia Mendez because it is an especially diverse and warm and welcoming community. I am passionate  about art in all its aspects (music, visual and performing).  I feel that when we encourage children to be creative we make way for the expression of the love inside their little souls. Outside of school, I enjoy spending time with my family and friends, going on hikes, taking trips, movie nights, impromptu family dance parties, cuddling with my little ones, and doing art.

Lucero Lupercio (Room 8)

I have taught at Sylvia Mendez Elementary since 2013 and I love it here! Students recognize me by my participation in our socio emotional assemblies. I believe that all students benefit from socio-emotional learning.  I hope that each student leaves third grade having learned the standards as well as with a sense of pride about their families and themselves. I grew up and studied in the California central valley, California State University Stanislaus. My parents are from Tlaquepaque, Jalisco. I love traveling to Tlaquepaque with my daughter and husband during the summers! Additionally, I love going on hikes, playing, and reading with my daughter, Romina.

Sandra Loza (K–5 Full Inclusion)

I was born and raised in Hayward and as a child I was in a TWI program which I loved. I instantly fell in love with Sylvia Mendez Elementary because of this connection. As a bilingual child, being in a TWI program was so crucial for me & it gives me great joy to now be a part of it as an educator. This is my 5th year at Sylvia Mendez as the full inclusion specialist. Many of you might be familiar with the learning center which is my office space, and most importantly a safe space for students when they are having a tough day. The biggest and most special change in my life is that I am now a mother to a beautiful baby girl, Olivia Rose!!

Cat Castillo, Mild/Mod Inclusion Teacher

Hi, I am so excited to join the Sylvia Mendez community! Students will call me Maestre Cat and I use they/them (occasionally she) pronouns. This is my first year in Berkeley Unified and I am coming from Bridges Academy and Melrose Leadership Academy in Oakland Unified where I taught for 3 years. I have lived in the Bay for almost 5 years, I was born and raised in Laredo, a bordertown in South Texas. I am very proud of my Chicano heritage and love being able to embrace that part of me as a bilingual educator. As a neurodiverse educator, I strive to create affirming and fun environments for learning for all students! Additionally, as an individual whose own schooling was not accommodating and/or affirming of my neurodiverse mind, my goal is to be the teacher I needed for every student I am privileged to teach. I studied Anthropology and History at the University of Texas at San Antonio and completed my masters and Education Specialist credential program at Alder Graduate School of Education here in the Bay Area. I currently live in Oakland with my partner and our 4 cats!

I believe every child has the right to access the world of books and that children of all ethnicities and children all along the gender spectrum should see themselves represented in books. I am passionate about working with our most vulnerable students to support them in achieving access to the curriculum, particularly reading. My greatest hope for this school year is that all our students rise to meet the challenges ahead to becoming confident bilingual, bi-literate scholars.

Jennifer Yuen (ELD Teacher)

Hello, my name is Jennifer Yuen! I'm very happy to join the Sylvia Mendez community as an ELD teacher.  I was born and raised in the Bay Area. For all of my 19 years in education in Fremont, Castro Valley, and now in Berkeley, I've worked in an ELD classroom with multilingual learners.  I was immersed for so long at the middle school level that I wanted a new challenge and fresh energy of teaching at an elementary school. 

Working with MLLs is one of my educational passions. I learn so much from them and their unique stories. After graduating from UCLA, I even taught English in China where I tried out teaching for the first time and learned more about my family heritage.  Aside from teaching, I love traveling, baking, exploring the arts, being in nature, and learning about different cultures--- in fact, one of my biggest hobbies for 16 years has been dancing in a ballet folklorico group.

I'm looking forward to a wonderful year working with the students, staff, and families at Sylvia Mendez!
