While there, he attended Franklin Elementary School, Roosevelt Middle School, and Port Angeles High School.
He then attended Whitman College in Walla Walla, Washington. At Whitman he earned an undergraduate degree in Mathematics and Physics and a Classics minor. He then completed a Masters' degree in Mathematics at Purdue University in West Lafayette, Indiana.
