My journey, since I was a young girl, I enjoyed building relationships.
Coming from a military background and having the opportunity to travel, developed a passion for learning and teaching others about celebrating diversity. Little Angels was created with this purpose in mind. Our curriculum was inspired by "Reggio Emilia Approach", therefore, we look forward to being co-learners together in developing our projects. I consider myself a lifelong learner. In 2020 | completed my Bachelor's Degree in Human Development at Pacific Oaks College. Throughout the years, there has been a shift in Careers, first my intention in becoming a Lawyer, then joining Chevron Corporation with a concentration in finance. Once my children entered high school I was able to pursue my new goal of opening a Center in 2001. My desire is to continue to support and guide family and community. As we begin this journey together, the key thing you should know about me is that I am 100% invested in your child success, so please don't hesitate to reach out to me if you have any questions, comments, or concerns, particularly if you have something personal you'd like to discuss with me Please feel free to contact me via email with any questions or support. We invite families to address any issues and concerns in writing. We value your thoughts, respecting that we are all unique individuals. Best practices, building trusting relationships with families is an essential component in providing a "High Quality" program. We look forward to growing and learning together!!! Building a true sense of community. Together we are stronger! Our Little Angels, Families and Staff look forward to an exciting year Ms. Estella Director, Owner I was born in Mexico, came to the United Estates when I was 9 years old. I grew up here in Antioch along with my brother and sister and cousins. I graduated from Antioch High School. I went to Los Medanos College to start my General Education. When I took a Child Development class I fell in love and wanted to look more into it. I met with the First 5 counselor, and she guided me to which classes to take. After I had my son, back in 2014, I took a break from school and working at a Grocery store was just not it for me. I quit my job and in Fall 2014 l started working at Los Medanos College Child Study Center in the 2-year-old classroom. After Spring 2016 l decided to focus on school and my son. In January 2017, l started my journey here at Little Angels Country School. In Fall 2024 | finally completed my AA in Early Childhood Education.
