About the Center


Welcome to the Kumon Center of Lake Grove! We are located on the west-side of Lake Oswego on Boones Ferry Road. We are now accepting new students. There is no charge for testing, please use the scheduling app on the website.

Students attend online sessions twice per week and receive daily homework. We operate on 30 minute appointments and work closely with every child.  Mrs. Debbie Siegel is the Center's owner/director and supervises the work and instruction of each student. She has four assistants who all work one-on-one. Our goal is to teach and guide students the skills needed to become independent, confident learners.
