Rebecca HardestyDSC_8087
Executive Director

Hello, my name is Rebecca Hardesty and I have been working with Smart StartCreative Learning Center since Newark opened in early 2010. I was introduced to Smart Start when my own son, Caleb, was 2 years old and attended the first Smart Start preschool.

I have been married to my husband Grant for 17 years and we are blessed with 3 children who keep us very busy. Caleb is 14, Connor is 13 and Olivia is 11.I have a Bachelor’s degree is Early Childhood Education and Master’s degree in Clinical Psychology. I have had the opportunity to work in many diverse settings, including Belmont Hills Psychiatric Hospital, San Mateo County Youth Diversion program, and several youth and family service organizations. I have over 18 years experience including my current position as Director for the past 6 years, teaching preschool, and providing counseling services to children and their families. In addition, I spent several years teaching Parenting Classes working for the reputable organization “the Parent Project”. Weekends we spend most of our time attending all the sporting events our kids are involved in. Soccer, Basketball, Cross Country, track etc., multiplied times 3 kids equals lots of running around from one thing to the next and traveling. I am incredibly grateful and thrilled to be involved with this program. Smart Start offers a unique learning environment that provides children opportunities to learn at their own pace in a joyful, fun and very creative environment. The teachers at Smart Start give 110% everyday and make sure each interaction with every child is meaningful. Smart Start staff challenge one another and your children to be the best they can be every day. I feel so fortunate to be a part of this exceptional program.

Hello, my name is Ms. Taylor. I have been fortunate enough to be with Smart Start since January of 2021, working in Stingrays and Tadpoles. I grew up in a large and blended family, helping raise my siblings alongside my single parents. I started working with children while attending Livermore High School, interning at a preschool. At age 21, I rejoined the child care/education world, working at a Dublin preschool for 2.5 years until I found Smart Start. I am currently working in the Tadpole classroom, ages 1.5 to 2.5. I also have done nannying for multiple families. I was born and raised here in Livermore and currently still reside here, so I am very familiar with my hometown. I live with my amazing husband, Curtis, and our two lovely stepchildren. Our off-time consists of hiking, traveling in our big truck, biking, playing with our kids, and watching old movies. I have completed 18 ECE units at Las Positas College and have years of experience working with children. What I love most about working with children is seeing their individual growth as tiny humans and being able to document and communicate that growth to parents. I aim to help create caring, honest, and confident Americans, I mean after all they are the future of our world! I look forward to what my career working with children has in store for me.

Hello I’m Alexsandra, but at Smart Start, I’m always hearing, “Ms. Sandra!” and that’s just the way I like it. I love being a teacher and I’ve always known I’d work with children. In 2015 I found myself in a classroom and never looked back. I’ve been taking classes and furthering my education through workshops and other outlets ever since. I recently obtained my AA in Early Childhood Development and will be working on obtaining my BA. Children learn through various methods Children are unique, so I enjoy creating activities that are playful, hands-on and expand the five major developmental domains in a unique way. This is why in 2019 I joined the Smart Start team because their school principles align with my own. I look forward to meeting you and getting to know your little one.
