Ms Holly

Holly Geiger, Center Director/Owner

Holly studied Biology with an emphasis in ecology and conservation at the University of Washington.  She took a job in the Information Technology field, which became her unintended career path for 15 years. Holly left the long hours and travel demands to raise her daughter. 

The parent of a student frustrated each night with math homework, Holly sought out resources to help.  After being referred to Mathnasium by a teacher, researching the Mathnasium method and seeing the positive influence it made in the lives of students, Holly decided to open a Mathnasium in her neighborhood. Now a whole community of 1st grade – College students can benefit from learning math in a way that makes sense to them, in addition to providing a resource for parents to stop the math homework struggle.

Mathnasium has hundreds of amazing success stories across the country as a result of the Inspiring Learning Environment, Teaching Style and Curriculum at Mathnasium! Let Mathnasium help your student begin their success story today!

Larry Martinek, Creator of the Mathnasium Method

Larry has spent his entire career finding a better way to teach math. From inner city public schools, to acclaimed magnet schools, to leading private and parochial schools, Larry has served as both a classroom teacher and as an educational consultant. He has designed curriculum, teaching strategies, and teaching materials to help students and teachers learn math more effectively. He has trained teachers in the art and science of boosting students' ability to “do” math, thereby increasing students' math scores and feeling of self-worth. Larry is the developer of Mathnasium’s educational program – one of the most comprehensive and innovative curriculas ever produced for teaching math.

While Larry is not an Instructor at our Center, he is a valuable asset we can call on to ask about specific students' scenarios for guidance and advice. This has helped to make visits more productive and enjoyable for many of our students.
