Mrs. Huynh

Melodie Huynh


Welcome to the 2018-19 school year! 


My name is Melodie Huynh, and I have been the Principal here at Hidden Hills for the past four years. 


I have been in the field of Education for the past twenty-one years.  After graduating from the University of Victoria, I began my career teaching middle school on Vancouver Island.  I then moved from Canada to California and started teaching high school Special Education at Castro Valley High School.  After that, I taught in the elementary grades for ten years (mostly at 5th grade).  I was then asked to lead our Summer School program and become the Principal of Palomares Elementary.  After multiple years in this role, I took on the added responsibility of serving as a Curriculum Coordinator at the district level.  My last few years in Castro Valley were in the role as Principal of Jensen Ranch Elementary.  I have been very fortunate to serve in exceptionally high-performing schools where academics are a priority, and families are involved and invested . . . not only that, but we have great kids!


I have two children of my own, Ethan and Matthew.  Ethan is starting his first year of college this fall, and Matthew is starting his first year of high school.  Lots of new beginnings in our household this year; did I mention that we are moving the weekend before school starts?  I have also submitted my application to begin a doctoral program this year.  I love to learn, and I hope to instill this passion in our students every day!


My door is always open.  Please let me know how I can make this year the best ever for you and your children!

I am looking forward to another great year at Hidden Hills as a teacher and a TSA. This is my 14th year teaching, and my 10th here at Hidden Hills. I am excited to be part of such a wonderful and dedicated school community!


I am a California native, originally from Orange County, but now I love living in the Bay Area. I received my bachelor's degree in Communications/Public Relations from Cal State Fullerton. During college, I had the opportunity to work at The Happiest Place on Earth!  Maybe you've seen me on Submarine Voyage, Matterhorn, or giving guided tours.  After graduation, I moved to San Francisco to work for a public relations agency. After a year, I realized that I wanted to do something more fulfilling and rewarding. I received my teaching credential from Cal State Hayward and taught second grade for four years in Richmond.  Here at Hidden Hills, I've taught 2nd, 4th, and 5th grades.


When I'm not working, I enjoy running, traveling, reading, eating, friends and family. 

Mrs. Reed

Donna Reed

Office Manager

I have been with the San Ramon Valley School District since 2008 and at Hidden Hills since 2011.  My previous experience includes Special Education, Educational Transcribing, Office Management, as well as having an Elementary teaching credential.  It is all of these experiences that I bring to my new position of Office Manager in order to work closely with the Administration, Staff and Parent communities.

In my free time I enjoy spending time with family.  If I am not at a Cross Country or Track meet, watching a Phillies or an Eagles game (yes, I grew up in the Philadelphia area!) or chatting with family members near and far, you can usually find me relaxing with my family, or in the kitchen with my daughter who loves to bake!  I also have a son in college at NAU. Thank you for welcoming me to your wonderful school and community!

Mrs. Scherer

Rebecca Scherer

Resource Specialist

I am so excited to be working at Hidden Hills! I have taught in other districts, but I couldn't wait to come back to the district that I went through as a student! I grew up in Danville and love the area and everything it has to offer.

I received my bachelors in education and special education at Chico State. I also received two teaching credentials from Chico State. 

Teaching is my passion and I feel lucky that I am able to be apart of the Hidden Hills community! I love being able to work with all grades and all students. I believe that every child deserves the very best education, and I am here to help support all our wonderful teachers and students here at Hidden Hills!

 I'm the Hidden Hills Library Media Coordinator. I was raised in Moraga and after living as an expat in Japan and Puerto Rico for 5 years my family returned to the area and we have lived in Danville for the past 17 years.  I received my Bachelor’s Degree in Business Management from St. Mary’s College and spent 10 years as a Marketing Communications Manager before beginning my second career, my “give back” career as the Library Media Coordinator for Hidden Hills.  I have worked for the San Ramon Unified School District in various roles for the past 10 years and am thrilled to have opened this school and developed our library program in 2004.  Working with the students, teachers and the community is truly a labor of love and I am so happy to share the joy of reading with our students.  My goal is to instill a love of reading that will last a lifetime for each and every child!

 I am excited to be part of the community because Hidden Hills' parents recognize that science plays a critical role in their child's education. I share my love of science with students through hands-on labs, show what we learn in class have real-life applications and how fun science can be at the same time. The goal is to awaken their enthusiasms, curiosities and fire their imaginations.

After moving to the States from Hong Kong, I studied zoology and nuclear medicine. I worked in both government and private sectors until my husband and I settled down in the valley to raise our two daughters.

Most evenings, you will find me reading either at the computer or with my nose in a book.  Weekends are time for family and friends while enjoying home cooked meals.  I am as thrilled as my students when summer rolls around.  That's when I explore new places especially museums and cuisines.
