Stephanie Brickman

4th Grade Teacher

I’m so excited for another school year to begin! This is my 10th year teaching, and my 8th year teaching 4th grade in San Carlos! I love being an educator because I get to work with such creative, thoughtful, curious kids everyday! I strive for my students to feel like an important part of our school community, be proud of who they are, and build their love of learning.


My favorite things about 4th grade are bringing the class together with Morning Meetings, diving deeper into engaging chapter books, and learning through various cross-curricular projects collaboratively! I love how 4th graders are ready to build their critical thinking skills (along with the 5Cs) through PBL, integrating technology, STEM Challenges, and more.


In my free time, I love being around my family, my cat, and my close friends. My family’s newest addition is my adorable 1-year-old nephew (who I am absolutely, hands-down obsessed with). I’m sure the class will hear all about him! (Update: He is crawling everywhere, and almost walking on his own!) Growing up in a large family, I’ve learned to value coming together amidst our busy schedules. On my own time, I love curling up with a good book, working out to 90s pop music, and tending to my flowers and succulents.


I can’t wait to see my students light up with enthusiasm this year and learn so much with me!

4th Grade Teacher

I began teaching in 2005 here in San Carlos - this is the start of my 19th year with the district. I have been teaching 4th grade for 17 years, wow! I taught at Brittan Acres for 12 years where I primarily taught 4th grade (with one year teaching 3rd/4th combination and one year teaching 3rd). I love having the opportunity to be collaborative as a teacher, and was lucky enough to convince Jen Heinschel to jump on board to 4th grade. She and I have been teaching partners for the last eight years. We get the opportunity to share students and meet our students’ needs with a rich and team-focused learning environment. Teaching brings me the most joy when I see kids realize their potential is limitless - that’s when magic truly happens!


Fourth grade has been my absolute favorite grade level to teach. Kids make so many strides academically in 4th grade, their creativity is astounding, and the curriculum is challenging but also a lot of fun to teach!


My husband and I are peninsula natives! Together we have two kids - my son is in 6th grade and my daughter is in 3rd grade. We love having time together going for walks with our dog, playing at the park, riding bikes, and swimming. I love to be outdoors enjoying some beautiful scenery and the warm sunshine. When I’m not in mom and teacher mode, I try to get some exercise in, read a book that has been on my long overdue list, or catch up on a Netflix series.


The start of a new school year brings a lot of excitement and wonderful, fresh experiences.



Jennifer Heinschel 

4th Grade Teacher

This is the start of my 21st year of teaching - I started teaching in the San Carlos School District and I’ve never left! I taught 3rd grade at Brittan Acres for about 10 years (with a 2/3 and 3/4 combination class thrown in there) and then transitioned to 4th grade where I was able to partner with Kelly Earlywine. We’ve taught 4th grade collaboratively for the last ten years and we love working together to meet the needs of our students. It’s the absolute best when you see the ‘lightbulb’ go on when you’re teaching, and when you see students start to nurture different passions within their own lives.


Fourth grade was one of my favorite years as a student in school (but, wow, I sure I wish I had learned math the way we teach it now!) and it’s by far my most favorite grade to teach! Students are really starting to develop their independent thinking and take their ideas to a higher level. There’s a wide variety of interests and skills - and 4th graders are just plain fun to talk with! I majored in journalism in college and love to teach writing and share my love of all things grammar to my students (they don’t always share my enthusiasm!). Reading is one of my absolute favorite ways to spend time, and you’ll find me ready to talk Harry Potter any time, any day.


My family is the most important part of my life. My husband and I have two kids. My daughter is 14 and my son is 12. While I can’t believe that my daughter started high school and my son is going into 7th grade, they make me proud every day. We have a dog (a result of me chaperoning my daughter’s Girl Scout troop to Pets in Need a few years ago) and a cat (who doesn’t really like the dog), a rabbit (thanks to a persuasive, researched presentation by my kids), and two birds. Yes, it’s a zoo! We love to spend time in our backyard barbecuing by the creek.


Ever since I started school, I’ve always loved the beginning of each year. School supply shopping was a favorite, with new pencils, a binder, folders, and erasers being just about the best thing ever. There’s something special about a fresh, new start every year - for both teachers and students.

4th Grade Teacher
This is my sixth year teaching in the SCSD and I have loved working with my students and collaborating with the fourth grade team at Mariposa. Previously I have worked for many years with different learners in various Special Education settings for about 10 years. I am also a SCSD parent and have great gratitude and appreciation for all of our educators, staff, school Board, and administrators.    
4th Grade is the sweet spot, the best! My favorite thing about 4th grade is building authentic connections with my students(and their families)and being inspired by their enthusiasm to learn and grow.   
My husband and I have 2 daughters, Gabi-17  and Elisa-13 who keep us on our toes-daily! They are both fun to be around and have a good sense of humor. Gabi is the Varsity goalkeeper for her high school team and soccer club and loves music. Elisa likes theater and music. My husband John was born and raised in San Carlos and is a Critical Care Transport pilot in CA. Our entire family enjoys the outdoors, spending time with family and friends, game nights, and challenging puzzles. I also love to read, listen to music, and visit the SC farmer’s market on Sunday. Each summer we look forward to hiking, biking, and camping in the Yosemite Valley with family friends and enjoy rafting and floating in the Merced River. We hope to win the Yosemite High Sierra Camp lottery someday!  I look forward to the new school year with my students mostly because I know how much growth, confidence, and independence will be happening. I’m amazed at what my students accomplish throughout the school year and am truly grateful for and inspired by them.

I’m so excited to be joining SCSD and to begin teaching at Mariposa! My teaching career began in Cupertino Union School District in 2006. Since then I’ve taught 3rd and 5th grade as well as 4/5 combo. I’ve loved my time teaching in Cupertino, and I’m ready now to join a new community that’s closer to my home in Redwood City where I live with my wife, Tristan, young sons, Piers and Reed (10 and 8), and Champers (adorable).
I’m a Bay Area native having grown up mostly in Portola Valley. I was also lucky enough to live in Brussels and Geneva for several years. Having always been engaged with music and the arts, I attended Rhode Island School of Design where I majored in film and video but also spent time working with 2D and 3D mediums as well as making music in a band. I still enjoy making art and music as well as spending time outdoors (hiking, camping, fishing, skiing, and surfing). My older son Piers is becoming an avid surfer and is a great surf buddy!
I went into teaching for the same reason as most: to make a positive difference in the world. Education is a wonderful field because success isn’t measured just by personal accomplishment. It’s measured by others’ success - students’ success! It’s this sense of shared accomplishment that motivates and inspires me to teach from the heart and be a lifelong learner. I can’t think of a better place to continue on this path than Mariposa!

4th Grade Teacher

I am so excited for another school year! This will be my 7th year teaching and my 1st in San Carlos! I am so thrilled for this opportunity and to get to know this community! I've always known I wanted to be an educator ever since I was in the 5th grade. I loved going into the kindergarten classes and helping out the teachers at my school! I love being a teacher because of the relationships we build within the classroom and I get to see the amazing progress these kids achieve every day! 


I love teaching 4th grade because the kids are so courageous and creative at this age! I was also born and raised in the Bay Area, so I love being able to teach about our Golden State. I love how conversations are deeper at this age and how collaborative the kids can be. I also enjoy teaching SEL and implementing projects throughout the year. I’m excited to see what this year will bring! 


When I’m not teaching, I love being with my friends and family, especially with my godchildren! I am a huge fan of watching the Warriors, Giants and Niners. After school, I am most likely at Orangetheory or in Hot Yoga. I also love being near the ocean, trying different foods, reading and traveling!

Room E

I began teaching in 2002 and have taught Pre-K through 5th grade.


I absolutely love connecting with the families and watching the students grow and persevere. Each year is an amazing new start with endless possibilities. I am so thrilled to welcome back our school family along with our amazing paras, Mr. Jones, and Ms. Jonah. We will continue to make wonderful memories in Room E as we journey through a year of hands-on experiences and small groups.


I enjoy spending time with my husband and seven year old son. We love time in the city exploring all of the wonderful restaurants.
