About the Instructor


Welcome to my Kumon Center of Ladera Ranch!

My name is David Holcberg and I would be honored to be entrusted with your child’s supplemental education in Math and Reading.

Whether you are looking to help your child catch up in school or surge ahead, I am here to help you achieve your goal.

My center offers a quiet, comfortable and disciplined study environment where your child can focus on completing his or her academic assignments independently or with the help of a teacher, in an accurate and timely manner.

I pledge to work with you and your child to create an individualized lesson plan within the Kumon curriculum that fits your child’s needs, and that aims to build a strong foundation in math and reading comprehension that is crucial for success in school and life.
