Hacienda Montessori
Where Children Learn and Discover

Hacienda Montessori Academy
Welcome to Hacienda Montessori Academy. We opened our doors for services in July 2010, and the program was received warmly by the residents of Hacienda Heights. It is one of only two Montessori based schools available in Hacienda Heights. We offer both private and State Preschool services for preschool ages two through entry into grade school.
We are proud of our beautiful campus and we take pride in our classroom environments which offer a variety of equipment and materials that are not commonly found in other Montessori classrooms. Apart from offering an authentic Montessori environment our classrooms also have materials and equipment which follow the principals and practices of Early Childhood Education. This philosophy is popular in American culture and utilizes the High Scope curriculum, Creative curriculum and the Environmental Rating Scale (ERS). The combination of both of these philosophies applied through their individual practices and unique equipment and materials creates a unique and rich environment for your child unlike that found in most preschool environments.

Our team of teachers are dedicated to providing your child a solid foundation for future success based on our set of goals and objectives designed for your children to express their creativity, unique individuality and achieve success in their daily work and play. They work one-on-one with children to ensure they strike the right balance between adult interaction and guidance and independent activity and free choice.
The Staff
We have a dedicated group of teachers there who have grown to love the community and believe it is their responsibility to prepare its young preschoolers with a wealth of knowledge, skills and confidence to be successful in the years ahead in grades school and beyond.
Our site supervisor has Montessori training, a bachelor’s degree in Child Development and well over ten years experience in working with preschool aged children in various child development settings. She is resolute in her dedication to preserving the Montessori Method, our mission, goals and objectives for our children and the unique combination of our curriculum, Montessori environment and vision for the children we serve. She is further characterized by her intelligence, kindness, caring and patient attitude and demeanor and willingness to work with families from all walks of life that are interested in enrolling their children in our program.


Meet the Site Director – Kit del Rosario MA
My name is Kit, also known as Miss Kit to many. I have been an Early Childhood Educator for over 30 years, earning a Bachelor’s degree in Social Science with a concentration in Education and a Master’s degree in Teaching and Learning with Technology, with an emphasis on Early Childhood Education. Throughout my career, I have embraced various roles—assistant teacher, teacher, lead teacher, master teacher, program lead, site supervisor, and director. Each position has deepened my understanding of early childhood development and strengthened my commitment to creating nurturing, engaging, and enriching learning environments for young minds. Beyond my professional journey, I am a proud mother of two—Mitchell, an honor student who is now a successful cybersecurity professional, and Megan, also an honor student and currently an undergraduate at UCLA. Watching them grow and succeed has reinforced my belief in the power of education and the importance of fostering a strong foundation in a child’s early years. My teaching philosophy is shaped by my diverse experiences, including my background as a musician and piano instructor, as well as my time as a ballet performer with The Royal Academy of Dancing. I have also found joy in baking and dessert styling, a creative outlet that has taught me patience, precision, and the beauty of craftsmanship. As I step into my role as the new Site Supervisor and Asst. Program Director at Hacienda Montessori Academy, I do so with a deep sense of responsibility and dedication. I am committed to supporting our team, partnering with families, and most importantly, nurturing each child’s natural curiosity and love for learning. I believe that every child deserves to be seen, heard, and inspired, and I am excited to contribute my experience, passion, and heart to this wonderful community.
