Bethany Bos

Bos attended Spring Arbor University from 2015 to 2019, where she was a four-year starter on its varsity soccer team. The Cougars advanced to the NAIA Final Four every year and won two national titles with Bos on the team. She was named the NAIA national player of the year three times and first-team All-American all four years. While in college, Bos played as an amateur with senior teams over the summer. She led Grand Rapids FC to a United Women's Soccer championship in 2017 – scoring hat-tricks in five straight matches – and played with Seattle Sounders Women in the Women's Premier Soccer League the following year winning the WPSL championship.

Seattle Reign

Bos was invited to the Reign FC preseason training camp prior to the 2019 NWSL season and subsequently earned a contract on the club's supplemental roster. She was the first NAIA player to sign with an NWSL club and only the third NWSL player to previously play collegiately in the United States and finish their collegiate career with a non-NCAA D-I institution. Bos made her NWSL debut coming on as an 86th-minute substitute at the Houston Dash on April 14, 2019. A week later, she made her first start in Reign's home-opener at Cheney Stadium. Curling a shot from the edge of the penalty area into the far corner of the goal, she scored her first-ever pro goal in the 21st minute against Orlando Pride in a 1–1 tie. It was also the first home goal scored in the Reign's first season in Tacoma, Washington. She scored her second goal in her second home start, sixth appearance on May 27, 2019, in a 2–1 win against the defending champions North Carolina Courage. Her 13th-minute header from the edge of the box crashed off the underside of the bar to give her side an early lead. Her third goal occurred in the next game in her third home start against the Houston Dash. On a breakaway she picked up a deflected through ball from Darian Jenkins and slotted right-footed past the keeper for the first goal of the game in the 32nd minute, Houston tied in the 90th to split the points. At the end of the season, she was awarded the 2019 Rookie of the Year Award. Bos…

Bos grew up in Hudsonville, Michigan and attended Unity Christian High School, where she played varsity soccer and basketball. She is the fourth of five children.
