Arroyo School is proud to have an excellent team of educators. A full list of the staff and email addresses can be found on the Contact Us page. 

Mindy Shelton, Principal

  • I started teaching 27 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. 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 9 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, 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.

Julie Jobak, Counselor, Shared with Central

  • I have been a teacher for 21 years and I have taught 4th-8th grade. I love helping people.
  • The students are so nice and cute and small.
  • I like hiking and spending time with my friends.


Katie Hultgren

Katie Hultgren, Librarian

  • I started as the Central/Arroyo librarian 9 years ago, when both my kids were students here. I enjoy being a school librarian because I love getting kids excited about reading! The part of the job I like best is making the Library a fun space that belongs to all the Arroyo and Central students.
  • My favorite thing about 4th and 5th graders is how interested all of you are in exploring the world and new ideas. 
  • My husband and I have a son and a daughter who are now young adults. In my free time I like to walk the neighborhood with my dog, Maysie. I also love doing word games, baking bread, and going out to coffee!

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. 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!
Nicole Murray

Nicole Murray, 4th Grade Teacher

  • I received my teaching credential in 2005 and have been teaching in San Carlos for 6 years. I have taught K-2nd and 4th-8th 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 15th 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, son and daughter. 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.

Michelle Sales

Michelle Sales (formerly Michelle Pastor), 4th Grade Teacher


  • I started my career in education in 2008 as a preschool teacher. I studied and moved to Italy to teach English as a Foreign Language and taught EFL for a few years. In 2013, I decided to go back to school for my Master of Arts in Education. I love being able to guide and encourage our future change makers to be humans this world needs.
  • My favorite thing about 4th grade is how intuitive these scholars are at this age. 9- to 10-year-olds are so observant of the world around them and what better way to discover their strength and abilities than in a community that fosters their curiosities, their identities, and their voices. 5th graders, honestly, never cease to amaze me.
  • I truly believe I am solar powered and one with the ocean — I love paddle boarding, hiking along the coastline, and reading somewhere outdoors. My husband and I are also avid Disneyland attendees and can’t wait to be annual pass holders again!

Sheila Sevilla, 4th Grade Teacher

  • I've been in the SCSD since 2001 and am starting my 26th 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 enjoy spending my free time outdoors trailing running, hiking, bike riding, or exploring new places.  I also like reading, baking, and being with family, friends, and my two dogs.

5th Grade Teachers


Marianne Cheatham, 5th Grade Teacher

  • I've been teaching on and off for 30 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). 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 24 years, 21 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. 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-1st 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.

  • I have taught high school students art for over 13 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. 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.
