Cooper Jansen was born and raised in Whatcom county and grew up playing baseball in Ferndale. He stared playing competitively when he was 10 and after years of playing in Cal Ripken, Pony, and Babe Ruth leagues he then played for Ferndale High School. A pitcher, first baseman, DH, and occasional outfielder Cooper was apart of multiple teams that were at the top of the northwest conference. He played for the senior legion Bellingham Post 7 baseball team the summer after his senior year and enjoyed playing with other ball players all across the county. After that he got the opportunity to play at Everett Community College and was lucky enough to be apart of the 2013 NWAACC championship team his Freshman year. He also played for The Everett Merchants, a summer team for college baseball players in between years at Everett. During this time, Cooper became a pitcher only and did not play any positions in the field anymore in order to focus on pitching. With that, the amount of innings spent on the bench/in the bullpen went up which allowed him to strengthen his knowledge of the game eventually motivating him to coach.
After Everett, Cooper accepted a scholarship to a small division 2 school in Oklahoma City, OK. He played one year there, but decided it was not the right fit and made the decision to move home to attend WWU and focus on his education with the goal of graduating with a business management degree. This also allowed Cooper the free time to coach so last year he was an assistant coach on the 13u green crush team. He loved every minute of last years experience and is back to continue coaching and preparing ball players to achieve their goals whatever they may be.
