Did you know Prime Numbers was founded by local educators Rena Pitasky and Martha Swallow?

Rena is the former Secondary Math Specialist for Issaquah School District.  She is also a National Board certified middle school math teacher who taught at Pine Lake Middle School for many years.

Martha is a former private school administrator and past president of Sunny Hills PTA.  She is a highly respected education consultant in our community.

Both Rena & Martha saw the need for high quality math support and enrichment in the Issaquah/Sammamish area, and decided to open Prime Numbers.

Stop by to visit our beautiful classroom space in the Discovery Heights neighborhood of Issaquah Highlands and learn how we can help support your middle or high school student with math.

Teaching math for understanding.
