Mindy Shelton, Principal

  • I started teaching 24 years ago at the elementary school I attended as a child. I taught kindergarten for a year and then 5th grade for 12 years before becoming a TOSA (Teacher on Special Assignment) focusing on school climate and wellness. I love helping students (and teachers!) discover new ideas that help them to be their best selves.
  • I love that 4th and 5th graders are able to think big and are beginning to understand so much more about the world around them. They really start to develop their own sense of identity and values.
  • I live with my husband and 2 sons (ages 12 and 17). I love to travel and spend time with friends. I'm a huge fan of musical theater and I love to listen to audiobooks and podcasts.



Tracey Olazar, Administrative Assistant

  • I have worked as a Para Educator and Administrative Assistant for the San Carlos School District for 6 years. I have worked at Arroyo, Brittan Acres, Central Middle School, and Tierra Linda.
  • In the 4th grade, we used to do a fun rainy day activity call Chicken Fat. It was a fast, fun exercise and we would all end up laughing.
  • I live with my husband, three daughters (16, 20 & 24), and our favorite family member Zoey, our black lab. I love to vacation with my family and friends. I enjoy music, the beach, horseback riding, boating, and camping.

4th Grade Teachers:


Jamie Skinner, 4th Grade Teacher

  • I have been teaching in the San Carlos School District since 2007 and have taught all grades 1st-5th. While I love teaching, I particularly love sharing my passion for learning with my students. We are all lifelong learners and one of my goals is to instill or grow the spark of passion for learning into every student in my class. Watching them make connections to the curriculum and then observing them putting learning into action is always exciting.
  • Fourth grade was the year I first truly realized that the world was so much larger than my little town of Steamboat Springs, CO. It was also the year I became consumed with learning everything about pioneer life and Westward Expansion. I love teaching 4th grade because I am passionate about our country's fascinating history and particularly interested in all things pioneer related. In 4th grade, students are making many cross curriculum connections and for me that is very exciting.
  • My family lives on a small ranch in Loma Mar, right next to where 5th grade goes for Outdoor Ed. It is a true treasure in the heart of the redwoods. My husband and our three daughters love taking care of our 50+ chickens, many goats, ducks, guinea fowl, and assorted cats and dogs. We have three daughters that we are very proud of; Hayley who is at UCSC, Bella who is at Cal Poly SLO and Rori-Kate who is a senior in high school. All three girls attended school in San Carlos, attending both Heather Elementary and Tierra Linda Middle School. Some of my most favorite things to do are cooking or gardening, and I especially love going on traveling adventures with my family. Together we have climbed 5 volcanoes and we are looking forward to climbing many more!

Kirsty Mooney, 4th Grade Teacher

  • I have taught for 16 years, Kindergarten through sixth grade. I love teaching because I get to be part of students' building of confidence and knowledge of who they are and what they are capable of, their excitement of a good 'I wonder' and 'ahha' moments, their stretch and beam of pride when they meet and or exceed their goals, and how enriched my life is in learning from my students.
  • My favorite thing about teaching 4th grade is teaching ALL the curriculum areas, seeing students connect cross-curriculum ideas and reach deeper understanding of the world around them and their potential.
  • I have been a San Carlos Citizen for 30 years (less 2 years and 3 summers spent in Arizona). I live with my husband Tim, and our mutt Ellie. I have three fabulous, grown up children Patrick, Moira and Sarah. I love spending time hiking, going to the beach, being in nature, visiting museums, and spending time with the people I love-family and friends.

Nicole Murray, 4th Grade Teacher

  • I received my teaching credential in 2005 and have been teaching in San Carlos for 5 years. I have taught K-2 and 4-8 in varying capacities. Being a teacher has been my dream since I was a little girl, and I am lucky enough to be living it!
  • My favorite thing about 4th and 5th grade is that they are old enough to engage in higher-level thinking, but young enough to give you a hug everyday.
  • I have a husband, two children, and a dog. When I have free time, I enjoy yoga, running, weight lifting, reading, and sleeping!
T, Lamb

Talia Lamb, 4th Grade Teacher

  • This will be my 12th year teaching! I have taught 5th, 6th, 7th, and 8th graders (primarily 6th and 7th grade) at Central Middle School for the first 11 years of my teaching career. I love teaching because every day is new and exciting - there is so much to learn between students and teachers!
  • I have really great memories of my 4th and 5th grade classes, the teachers, the projects, and the books we read during the read-alouds after lunch. My parents like to remind me how I did my mission project on Mission Santa Barbara, which they believe later inspired me to go to UCSB for my degree! I'm really looking forward to teaching the 4th grade curriculum and getting to know my students across different curriculums!
  • I live locally with my husband and two kids, my son (3) and daughter (1). We love our weekend and summer adventures around the bay, going to the mountains or the beach, trying new restaurants, and cruising around town on our bikes.

Sheila Sevilla, 4th Grade Teacher

  • I've been in the SCSD since 2001 and am starting my 24th year teaching. I've taught 4th grade, as well as 1st, 2nd, and 6th grade. I enjoy sharing my enthusiasm for learning with students and helping them get excited about learning as well! I find the 4th grade curriculum very interesting and I love to share my passion for the "Story of California" with my students.
  • It's funny because honestly, my two favorite teachers were, in fact, my fourth and fifth-grade teachers! My 4th-grade teacher, Mr. Schulman told lots of corny jokes and would throw a rubber chicken in the air if someone answered a question correctly. My fifth-grade teacher, Mr. Boudett did a lot of current event competitions and if you won you could pick a prize from items that he brought in from his house! Both teachers connected with their students and left impressions on me that have influenced me as a teacher.
  • I live with my husband and two daughters (11 and 14), as well as our senior dog (18). I enjoy anything outdoors, some favorites are: trail running, hiking, and bike riding. I love spending time with my family (especially in the mountains), traveling, and reading!

5th Grade Teachers:


Marianne Cheatham, 5th Grade Teacher

  • I've been teaching on and off for 27 years. I have taught 1st thru 5th grades. I love seeing the lightbulb go on in the students minds when they understand a new concept and learning about all the different personalities in my class each year.
  • I love going to Outdoor Ed with the 5th graders. It's such fun to see the kids outside of the classroom. You really get to see their personalities shine.
  • I am married and have 3 daughters and a dog. My girls all went through the San Carlos schools (WO and Central), and are now in college and at Sequoia HS. Outside the classroom I enjoy spending time with my family and friends. I love reading, listening to music, baking, and being outdoors.


Jennifer Crettol, 5th Grade Teacher

  • I started teaching 5th grade in 2007 at Central Middle School. I taught 5th grade for nine years at Central, then transferred to Arroyo in 2016 to continue teaching 5th grade.
  • I remember going to Outdoor Ed when I was in 5th grade ~ beach day was my favorite day!
  • I am a Disney fan! I love all things Disney, especially going to Disneyland with my three children!!!

Shelli Murphy, 5th Grade Teacher

  • I have been teaching for 21 years, 20 of which have been in San Carlos. I taught Kindergarten for one year, before finding my sweet spot teaching upper elementary students. (5th and 6th grade)
  • I moved to a new school when I was in 5th grade, and it was one of the most important moments of my life! I'll never forget how welcoming everyone was at my new school, and have tried to carry that spirit with me throughout my teaching career.
  • I'm someone who is constantly on the go, and thrive on being active. Spending time with my family fills my bucket! We have two boys, a junior in high school, and a 7th grader. I'm a devoted hockey mom, and my husband and I love nothing more than watching our boys play.

Angela Naughton, 5th Grade Teacher

  • My teaching career began in 2003, in Arusha, Tanzania, where I volunteered in a K-1 classroom. Since then, I have taught grades 2-8, as a classroom teacher and Resource Specialist. My favorite part of teaching is how every day is different, and brings both triumphs and challenges. Teaching also allows me to be a perpetual "student", as I am continue to learn new things every day!
  • My favorite thing about 5th grade is how it acts as a bridge to middle school. The students are learning to navigate their way to becoming young adults, and show a tremendous amount of growth as they finish their elementary school years.
  • I enjoy reading, writing, exploring new parks and trails, and spending time with my family in San Francisco and Lake Tahoe.

Michelle Robinson, 5th Grade Teacher

  • I started my teaching career in 1997.
  • I have enjoyed teaching both in the middle school and elementary level -  8th, 5th, 4th and 3rd grade.
  • Hobbies: I LOVE laughter and enjoy spending time with family and friends. My favorite place to be is the beach. When I’m not teaching, I love to read and spend time with my family.

  • My favorite things about 4th and 5th grade is that the students are more independent, funnier, and even more kind and thoughtful beings.
  • My favorite things to do are spending time with my family and friends, reading, and volunteering. 
Jade McMahan
Jade McMahan, School Psychologist

  • I have been a Speech Language Pathologist for 17 years, including 6 years in San Carlos, where I have served preschool through 8th grade students.  I am passionate about my profession as working with kids brings me continuous joy.
  •  I live in San Francisco where I met my husband playing kickball in Golden Gate Park. We have an eight-year-old daughter and are all obsessed with our eleven year old French Bulldog, Kezar.
  • This summer I enjoyed working as an Assistant Facilitator for Virtual Camp Shout Out for Kids Who Stutter.  Previously, I loved attending the Michigan based camp in person and now take my own daughter to Mother Daughter Camp at the YMCA every chance we get.  It’s one of our favorite activities.

  • To this day I still remember my 5th grade teacher. Her enthusiasm and love for her students had a very positive impact in me.

Katie Gotelli, Para Educator

  • I have worked in education for over 10 years. This will be my first year as a Para Educator at Arroyo. My first two years at Arroyo we’re spent teaching Makerspace.
  • 4th and 5th grade is such a unique time. I’m glad our students have a special school catered just for them.
  • I have two sons, a 7th grader at Central and a 4th grader at Arroyo. My boys love to play baseball and we love to go to baseball games together.



Veronica Rossi, Special Education Educator
  • Five years ago, I was encouraged to return to the classroom after a 30-year stint in the business world. Initially I supported students from Central’s day class pushing into gen ed courses and the extraordinary teachers who welcomed these students into their classrooms. Working as part of a team to increase students’ self-esteem and academic skills was a joy! I worked with students in grades 5 through 8. Fifth grade seemed to be a pivotal year to me. So, when Arroyo opened, I followed some of my colleagues across campus. I have had the pleasure of working with an amazing fifth grade team for the last three years.
  • Fifth grade is a pivotal year on several levels. Course work is more rigorous, so academic stamina needs to be encouraged. Hormones enter the picture causing big changes physically and emotionally. It’s a confusing time. All students and especially sped students need a little extra attention. I am happy to be part of the team that provides this additional support.
  • Education is a family affair! My older daughter, Dr. Loraine Rossi de Campos is principal of Westborough Jr. High. Our son-in-law, José Campos is the coordinator of the Business Tech Academy at Woodside High School and my husband, Mike subs in grades PK -12 in our hometown of Half Moon Bay. The two outliers in our family are my younger daughter Margaret Widlund and our son-in-law Justin Widlund. They are attorneys and live in the Seattle area. We all enjoy hiking and traveling.
School Counselor:
Julie Jobak, Counselor 40%
  • I have been a teacher for 18 years and I have taught 4-8th grade. I love helping people.
  • The students are so nice and cute and small.
  • I like hiking and spending time with my friends.
Exploratory Wheel & Enrichment:

Colyn Fischer, Orchestra and Music Fundamentals

  • I've been teaching music since 2005, starting in my native Pennsylvania and since 2008 here in San Carlos. Before that I was a professional violinist in Pittsburgh and Chicago.
  • I've been playing violin since 1980 and after school I put my musician cape on and try to make the world a little more awesome with my fiddle!
  • I have a cat named "Petunia" with lots of whiskers and personality who likes to sing at night.
  • Hobbies: Hiking, camping, travel, reading, writing, listening to good music and making art!!!

Sarah Moulder, Director of Bands

  • I have been teaching middle school band and orchestra for ten years. I love this age group. Students at this age group are excited, eager to learn, and full of curiosity. Nothing is better than those light bulb moments!
  • This is my first time teaching 5th grade music! I'm excited for the challenge!
  • I love to play in pit orchestras for musical theater and to spend time with family and loved ones.

Heidi Geiges, Makerspace Teacher

  • I have been teaching since 1999, all in the San Carlos School District. I've taught 3rd, 4th, and 5th grades and have worked at Brittan Acres, Central (when it used to be where Arroyo is now), Heather, and Arroyo. Last year I worked at Mariposa setting up and starting their Makerspace for the 5th graders while also running the Arroyo Makerspace for both 4th and 5th graders. This year, in addition, to teaching Makerspace at Arroyo for fourth graders, I will be teaching Design/Innovation (7th/8th graders), Technology Skills (6th graders), and Computer Science (7th/8th graders) at Central Middle School.
  • My sweet spot in teaching is definitely 4th and 5th grade, which is obvious from my experience. My favorite things about 4th and 5th grade are the students are learning new responsibilities, being accountable for themselves, and discovering who they are as people as they get ready for their next big transition, middle school.
  • I am a born and bred New Englander, originally from Connecticut. I love going to the theater, art museums, and listening to live music. Some might call me a "concertaholic!" I also enjoy being outdoors hiking and exploring the many vineyards in the Bay Area!
Staci K

Staci Kavanagh, Art Teacher

  • I have taught high school students art for over 10 years. I love guiding the students through the creative process and helping them create something that they are proud of.
  • My favorite thing about teaching 5th graders art is that they do not have the self doubt of older children. They believe that they can do anything and their creativity is boundless.
  • I have two boys that are in 3rd and 5th grade. We like to do art projects and bake together but most of my time is spent taking them to sports and piano practices and coaching sports teams. I have coached my son's baseball team since he was in kindergarten.

Gustavo Romero, Head Custodian

  • I have been working for SCSD for 4 years.
  • In 4th/5th grade, I enjoyed recess, especially playing football on the blacktop.
