Joanna Fennema

College Fennema attended the University of North Carolina. In her first year with the Tar Heels she made 23 appearances all as a substitute. In 2014 she started in all 20 of her appearances. In 2016 she took a red-shirt season in order to recover from back-to-back ACL tears in both knees. She returned for her senior year in 2017, helping the team win the 2017 ACC Women's Soccer Tournament and was selected to the All-ACC Second team. Her college coach Anson Dorrance said Fennema was "technically my most gifted player. Even if you look at our entire history of our brilliant technicians she ranks right up there with the Tobin Heaths and the Meghan Klingenbergs and some of the best technical players that we've ever had here at UNC." but the team folded one week later. She was picked up in the third round (25th overall) of the 2018 NWSL Dispersal Draft by the Chicago Red Stars. She spent the 2018 season with the team's reserves in the Women's Premier Soccer League.

Orlando Pride Fennema joined Orlando Pride for the 2019 season, signing to their supplemental roster on April 10 after impressing new head coach Marc Skinner in preseason. She made her debut on April 14 in the team's season opener at home to Portland Thorns. On June 15, she scored her first goal for the team, a free kick in a 2–2 draw against Houston Dash.

Fennema retired from professional soccer after suffering a back injury on February 28, 2020.

In 2014, Fennema was called in regularly to train with the U-20 squad but was one of the final cuts before the 2014 U-20 World Cup. Previously she was the Assistant Soccer Coach of Columbus State Cougars from 2020 to 2023.
