My journey here at Palomar College began as a student right after high school.  Once I completed my GE and first Child Development course, I transferred to Humboldt State University and earned my BA in Child Development.  After returning to the San Diego area, I earned my MS from National University.

I have been working in the field of Child Development since 1986.  Over the years, I have worked in just about every setting, from a licensed family child care, a before and after school program, Head Start, a private for-profit center, and a state funded center.   I have had just about every position available in the field from aide to director.

I began my work career at Palomar College in January of 1995 as a teacher of the 2-3 year olds at the ECE Lab School on campus.  While at the Lab School, I was a teacher, site supervisor, and coordinator.  While at the same time, I began teaching as part-time in the Child Development Department in 1996 and became full-time in 2000.  I have also served as Department Chair.  One of the best parts of my job is not only to teach Child Development classes, but to also be the ECE Lab School Liaison.  I have been the Liaison since 2003.  I am the link between the Center and the administration on campus.

On a more personal note, I met my husband while taking a communications class here at Palomar.  We were married in 1995 and have a wonderful teenage son, who is always challenging me to use my education and experience.  I was born and raised in Escondido and live there with my family.  When I have some free time, I enjoy photography, needle work, gardening, and doing anything hands-on.  Even as the years go on, each and every day I am thankful for all that Palomar College has given to me.

My name is Tamara Holthaus and I am the Early Childhood Education Lab School Coordinator. I have been an early childhood professional for forty years, twenty years as a teacher, and twenty years as an administrator.  I am also an instructor at Mira Costa, where I teach night classes for the Child Development Department.  I have three adult children, and we are all happy residents of Oceanside, California.

I have a passion for this field and believe that all young children should have access to a high quality program.  Our program demonstrates high quality in every way and in every classroom.  I feel very privileged to be part of the ECE Lab School team; it is an honor to work in a program with such high standards.  I would like every parent to know it is my goal for all Lab School children in our program to develop a lifelong love for learning.  This can only be achieved by providing children positive guidance and meaningful learning experiences.  It is our mission to strive to meet the needs of every child and family in our program.

I have “grown-up” professionally at the Palomar College Early Childhood Education Lab School (formerly Child Development Center- CDC). My journey began in 1994, as a Palomar College Child Development student doing observations at the CDC.  Shortly after, I started working as a Teacher’s Aide and continued to be promoted within the program.  In 1997 I earned my Bachelor’s degree from CSUSM in Liberal Studies and was promoted to the Master Teacher position. I was thrilled to begin the next phase of my professional career.  I thoroughly enjoyed teaching toddlers and learned so much from the seasoned teachers in the program.  In 2003 I resigned from my position and for the next 11 years, was fortunate to be able to stay home and educate my own children.

In May 2014, I started back at the Early Childhood Education Lab School working part-time. Currently, I hold a Director Permit through the California Department of Education. As of January 2017, I have a full-time position as a Site Supervisor-Leadership position. In this position, I wear many hats-from enrollment specialist, to oversight of the food program, maintaining our website, keeping our wait-list data up to date, creating and disseminating promotional materials, organizing, designing, and distributing the monthly newsletter, and assisting in the classroom as needed. I enjoy the opportunities to assist our families and build relationships with them. I am always excited to share our program with families and watch the children grow and develop a love for learning at an early age.

When I am not working, I can be found playing games with our three children, enjoying one of my husband’s culinary creations, spending time outdoor with my family, taking photos, cross-stitching, baking, or working on a digital art/design project.  One of my passions is giving back to the community; my family and I are involved in a few community programs/clubs for youth.

It has always been a passion of mine to work with young children. Seeing their growth and development over a short period of time is extremely rewarding and fulfilling. It is my pleasure to work at the ECE Lab School as a Site Supervisor.

I began my career working with children in 2007 at a small preschool in Escondido. After gaining experience, I moved to a larger preschool within a school district setting out on the coast. There I was a lead classroom teacher, office assistant, and an after-school headteacher/enrichment coordinator. I am very excited to be a part of the leadership team here at the ECE Lab School.

My education journey started in 2007 when I began taking Child Development courses here at Palomar College. In 2010, I transferred to Cal State San Marcos where I received my BA in Human Development with an emphasis in Children’s Services. After a brief pause, I returned to school at Pacific Oaks College and achieved my MA in Early Childhood Education in 2014.

While taking classes at Palomar College in 2008, I met my husband Jose. We got married in 2011 and have 2 dogs, and 1 cat. In 2016 we moved from Escondido to Temecula, CA, and love it! We are very excited to have welcomed our first child in February 2019! In our spare time, we enjoy off-roading in the desert, camping in the mountains, and creating DIY projects around our house.
