Dawn Murray-Sibby
TVHS - Email Dawn

I am Dawn Murray-Sibby, 25-year teacher with Temecula Valley Unified School District. I arrived in Temecula when I was 14 years old, before the city incorporated, as a freshman at Temecula Valley High School where I teach today. After graduation, I attended Cal State Fullerton where I received my B.S. in Child Development; I then received my teaching credential through Chapman University. Because I worked in banking during college, all of my undergraduate hours for graduation (120 hours) were achieved on a volunteer basis at TVHS. I received my Masters in Education, Curriculum, and Instruction, in 2001, also from Chapman University.  I teach in the Social Science Department; I have taught Geography, Psychology, World History, Fastrack-ASC freshman study skills, U.S. History, Child Development Program (CTE), as well as my current teaching assignment, Government and AP Psychology.

I became involved with TVEA many years ago as a site representative after telephone banking and precinct walking as a member starting in my first year of teaching,1995.  I Co-Chaired Organizing Committee that planned the first annual Fun 2B Fit Event.  I am now looking forward to supporting high school site representatives throughout our district, as the High School Area Representative.

I am married to Edward Sibby, former TVEA President 2008-2010, now CTA Communications Staff for our region in CTA, Region 4. We have four daughters and a new granddaughter born in July of this year.   We have TVUSD-TVHS graduates who went on to Berkeley and UCSD.

1st Vice President
Edgar Diaz
GMS - Email Edgar


¡Saludos! to all of my colleagues. 

Edgar is currently in his 20th year of teaching, He's not quite sure how it has passed so quickly.  He grew up in Whittier, a community outside of Los Angeles.  Edgar graduated from U.C. Berkeley with a major in History, intent in teaching at the high school level in a disadvantaged area. 

As it turned out, he was hired for a 5th grade teaching assignment in Fremont, California at the dawn of class size reduction.  He knew that he wanted to help underachieving students connect with the community around them, but didn’t realize he would enjoy accomplishing this with children at this age level. 


In 2004, he and his wife made the heartbreaking decision to leave the Bay Area and move closer to family with their own growing family.  For 7 years he enjoyed working with the dedicated staff and motivated students of Vail Elementary. Now he's made the jump to exploring topics in U.S. History with 8th grade students at Gardner Middle.  

Currently Edgar is our 1st Vice President for TVEA.  Although time consuming, he takes great pride in giving back to the profession he loves, and allowing his colleagues to focus on what matters… teaching.  

Edgar now has a family of 6.  His wife Yolanda works at Elsinore Middle as a 7th grade RSP teacher.  You might see Edgar's children as they follow him from meeting to meeting.  He is usually coaching soccer recreation teams, so that he can spend time with his kids and work with players on running, tackling, and developing toughness.  What a break from the modern classroom!

Elementary Area Rep
Karie Shorack

VHES - Email Karie

My name is Karie Shorack.  I am your newly elected Elementary Representative.  This is a new role for me and I am looking forward to working with the Executive Board, Leadership Council, and individual members to give support anyway I can. 


This is my 19th year teaching in TVUSD.  I taught Kindergarten for 12 years.  Currently, I am starting my seventh year in 4th grade.  I received my teaching credential from CSUSB.   In addition, I completed a Master’s Degree in Curriculum and Instruction in 2012.  

Temecula has been my home for 21 years.  I live with my husband of 36 years and my dog Kashi (yes, like the cereal).  Kashi is a Sheltie.  My two adult sons are Ted and Wesley who live in Oregon.  They both graduated from CSU San Marcos and are successfully navigating their 20's - Hooray! 

 I have been involved with TVEA as a member for 19 years, Site Representative for 5 years, and Elections Chair for 1 year.  I have learned a lot through my involvement.  I feel that communication and knowledge is powerful.  After becoming more involved, I realized that TVEA Leadership strongly advocates for its members, strives to communicate and educate its members, and holds OUR best interests in mind. 

As Elementary Representative, I hope that I can be helpful and supportive to  members by engaging and facilitating each of us so that our voice is strong and represented.  One of our goals is to meet more regularly with members to listen to concerns and have a successful year in TVUSD. 



Middle School Area Rep
Lauren Davis

DMS - Email Lauren


My name is Lauren Davis and I am excited to be in a more involved TVEA role as your Middle School Area Representative. Like many members I started as a Site Rep., then last year upped my commitment by participating in the LCAP Committee. I learned a lot through this committee and the education and involvement from this committee inspired me to take on a more active TVEA role. I hope to unite the middle school Site Representatives as a collective powerful voice and improve communication amongst us.

I began my teaching career at TES in 2003 after spending my first career as a Technical Sales Rep. After three years as an elementary teacher, I moved to DMS and have been here ever since! I currently teach Computer Science (CTE) and Science. Although I have taught a few different subjects and grade levels over the year, Science continues to be my most favorite.

In the last five years, I have earned my master’s degree, my CTE Industrial Arts and Technology credential, and am finishing up my Single Subject Biology credential now. School, school and more school! In addition, I saw my oldest son off to the Navy and graduated two other kid’s from High School. My youngest is a sophomore at TVHS (empty nest is in sight!).

Thank you for the opportunity to serve as your Middle School Area Representative on the Executive Board!
